Can you give me the name of Part 145 (MOA) organisations in [EASA member state]?
According to the Part 145.1 EASA is the competent authority for organisations located outside the EU territories. Within the EU Member States each National Aviation Authority (NAA) is the competent authority.
In accordance with above specified regulatory paragraph, EASA publishes the list of valid and non-valid Foreign EASA Part-145 approvals located outside of the EU Member States which are issued by EASA.
Following the same reference each EU NAA is tasked to issue a similar list of approvals granted on its own territory. Unfortunately not all EU NAA do have such a list of national approvals or even a website.
For the moment we can provide you with the list of EASA member states on our website.

For submissions of applications via email and provided that the application is complete, we will acknowledge receipt within two working days and provide you with the EASA project number.
As soon as your project has been allocated either to an EASA PCM or externally, you will receive the EASA Acceptance Letter providing you with the contact details of the PCM. The technical investigation may begin. Below please find the administrative milestones for your application:
I am applying from a non-EASA Member State, what requirements are there?
As per the Technical Implementation Procedure (TIP) with the FAA (US) and TCCA (Canada), applicants applying to EASA have to submit their EASA application via their local FAA/TCCA office and request that their application be forwarded to EASA. The FAA/TCCA will forward the complete application package to EASA together with the FAA/TCCA concurrence letter. Applications that have not been forwarded via the FAA or the TCCA are considered incomplete and cannot be registered.
I am a US applicant, what are the benefits of the recent TIP revision 6?
Please note that TIP revision 6 has been published, please click here.
This Revision of the TIP is the first milestone of the implementation of the validation improvement roadmap signed between EASA and FAA in February 2016. All design changes now have common approval path:
- Accepted (The approval or certificate issued by the certifying authority are automatically accepted by the validating authority)
- Streamlined validation (Basic) (The validating authority issues its certificate on the basis of the certificate issued by the certifying authority without technical involvement)
- Technical Validation (non-Basic) (The technical validation is performed by the validating authority according to a work plan focused on safety emphasis items)
This revision extends to all repair design their acceptance by the validating authority, removes the last restrictions to the acceptance of ETSO/TSO approvals and introduces the concept of Basic Type Certificates (limited to piston engines and propellers). It will enter into force 6 months after its signature on 22 September 2017 in order to train EASA and FAA personnel.
I am a BASA applicant (US/CAN/BRAZIL), how do I use the EASA Applicant Portal?
The bilateral applicant will complete the application data in the Applicant Portal and press “Submit”.
The Applicant Portal will send an email to the applicant with the application data summary document (Application Acknowledgement, FO.APMAN.00046) attached to it.
The applicant forwards the document to their National Aviation Authority in lieu of a completed EASA application form.
Meanwhile, EASA will change the application status in the Applicant Portal to “Waiting for FWD Letter – Eligibility Check” .
The National Aviation Authority reviews the application and forwards it together with the forwarding letter to EASA.
EASA performs the full eligibility check and, if applicable, changes the application status in the Applicant Portal to “Registered”.
The technical checks and investigation can start upon formal EASA acceptance.
Can a US applicant use the EASA Applicant Portal?
The US applicant can indeed submit the application online to EASA via the portal.
An online application document is then generated, which replaces the current application forms as you know them.
In order to stay in line with the bilateral procedures, the US applicant will send the online application document together with the requested data for the validation request to the responsible FAA ACO which will forward the complete validation request to EASA along with the FAA concurrence letter.
EASA ensures that only once the FAA letter is received along with the application summary document and the requested data for the validation request, EASA will further proceed with the application registration.
The EASA Applicant Portal simply logs the application, which is held pending until the FAA has reviewed the application and provided EASA with a concurrence letter. It is not required for US applicants to upload supporting documents for the validation request to the EASA Applicant Portal.
The EASA Applicant Portal is currently set up to only provide the applicant with an acknowledgement message, not the FAA. As can be seen in the illustration, it is incumbent on the US applicant to actually notify the responsible FAA ACO of their EASA application by providing the online application document to the FAA. Once notified by the applicant themselves, FAA can initiate the review of their submission and only then can the FAA provide EASA with the required concurrence letter.
Once EASA receives the FAA concurrence letter, which confirms that the FAA has conducted their review of the application, only then will EASA perform their full eligibility check of the application, and once eligible, the EASA task number is assigned and the technical checks and investigation will start.
For further information, please consult the extensive EASA Portal user guide.
The purpose of this message is to clarify to FAA certification staff and US applicants the use of the new EASA Applicant Portal.
The new EASA portal is an alternative to the previous procedure of having to use MS-Word forms when submitting applications for design approval to EASA.
Applicants can easily register to the EASA Applicant Portal by sending a simple email to Applicant [dot] Portal [at] easa [dot] europa [dot] eu.
Please find below an explanatory note on how the submittal process for US applicants works in order to stay in line with TIP procedures:
While the MS-Word forms are still acceptable, online submittal of applications over the Applicant Portal is now the preferred method by EASA for receiving applications.
The overall application process to EASA under the TIP remains essentially the same.
Can a Canadian applicant use the EASA Applicant Portal?
The new EASA portal was introduced under TIP Rev. 2. It is an alternative to the previous procedure of having to use MS-Word forms when submitting applications for design approval to EASA. The applicable TIP provision citing use of the Application portal is provided below:
2.3.1 Submission of an Application
(i) For EASA: Application Forms
Questions have been raised, suggesting the new on-line portal deviates from the TIP procedures that requires TCCA office submit the application to EASA. Use of the new EASA Application portal puts the applicant directly “submitting” an application before TCCA has the chance to review and endorse such application.
You will find below an illustration explaining the process and sequence of the new portal. The use of the new portal (which is an on-line application) replaces the previous filling of MS-Word form. Once the on-line application is filed, the Canadian applicant will receive an acknowledgement message that an application has been filled. This on-line application will not be processed yet nor validated outright. It simply logs it, and is held pending until such time TCCA has reviewed the application and provided EASA with a forwarding letter.
The EASA Applicant Portal is currently set up to provide the applicant only with an acknowledgement message, and not the TCCA. As can be seen in the illustration, it is incumbent on the Canadian applicant to actually notify TCCA of their EASA application by providing the Applicant Data Summary (FO.APMAN.00046) to TCCA. Once notified by the applicant themselves, TCCA can initiate the review of their submission and only then can TCCA provide EASA with the required forwarding letter.
Once EASA receives the TCCA forwarding letter, which confirms TCCA has conducted their review of the application, only then will EASA perform their full eligibility check of the application, and once eligible the EASA task number is assigned and the technical checks and investigation started.
The EASA Portal guide can be accessed at the following link: EASA Portal guide
If a Canadian applicant elects to use the MS-Word forms, the forms cannot be electronically submitted via the portal. The MS-Word forms have to be filled by the applicant and a copy submitted to TCCA, who in turn will file the application to EASA. While the MS-Word Forms are still acceptable, EASA prefers the transition to using the on-line application portal due to the efficiencies brought to the process (drop down boxes ensure the correctness of Applicant information, EASA product list, etc.).
The new Applicant Portal requires our applicant to notify TCCA that they have filed an application to EASA that without such notification, their application will not be processed further by EASA.
The overall application process to EASA under the TIP remains essentially the same.
Am I eligible to apply for an STC, Major Change or Minor/Major Change to STC?
Major Change approvals can only be applied for by the Type Certificate holder.
For minor or major changes to an existing STC only the STC holder is eligible to apply (EASA FO.CERT.00031 and FO.CERT.00032).
Alternatively, you may apply for your own STC using EASA form FO.CERT.00033 but need to demonstrate part 21 eligibility i.e. be a Design Organisation Approval holder if you are an EASA Member State applicant. Alternatively, you may contact a DOA of your choice.
Part 21.A.14(c) provides the possibility for any natural person to apply for an STC on an ELA 1 aircraft by demonstrating capability through a certification programme. Alternative procedures are not necessary. ELA 1 is generally defined as aircraft with a max MTOW of 1200kg or less, including balloons up to 3400m^3 and sailplanes.
ELA1 aircraft’ means the following manned European Light Aircraft:

Non-EU applicants do not need to demonstrate part 21 eligibility if a Bilateral Agreement/Working Arrangement is in force.
For further information on Design Organisation Approval (DOA) and Alternative Procedure for Design Organisation Approval (AP DOA), please refer to the following FAQs.
How much does my application/certificate cost?
Can a DOA with low STC activity decide not to implement LOI processes and continue to operate as before?
No, LOI will become mandatory through the amendment of Part 21 and applies to all projects but an applicant’s proposal is required for major changes, major repairs and STCs.
If there is an automatic validation of (E)TSO/STC, will there still be an EASA reference and FAA reference for the same modification?
No, only the primary certification authority’s reference.
Does LOI only apply to major changes and major repairs on aircraft for which the DOA is not the TCH?
No, LOI applies to all projects but an applicant’s proposal is required for major changes, major repairs and STCs.
Is there a Part 21 Light (DOA\POA) for STC holders for production of low volume STC and limited failure effects (non HAZ/CAT) planned (not only for GA)?
Yes, see rulemaking task (RMT).0018 (former task number 21.026). The “Part 21 light” concept is a concept related to the GA Roadmap Project and as such will be applicable only to the low-end General Aviation. The question seems related to STC applicable to all products, but considered as simple. This can be addressed today in the context of the actual regulation. The scope of the DOA can be limited to this kind of activity, and the limited scope would lead to a simplified investigation and surveillance activities. Furthermore, the concept of Level of Involvement (LOI) could allow the product certification team to reduce their level of involvement if the level of criticality is low and if the DOA is performing well.
Regarding the abandoned and surrendered STCs, will EASA follow the same guidelines as FAA 8110-120, especially regarding the requirements for Freedom Of Information Act FOIA?
The FAA 8110-120 does not apply to EASA. Even if there is no extensive series of examples regarding surrendered or abandoned STC, the Agency principle, similar to the TC case, is that in case of surrendered STC, the Agency keeps the responsibility on the TCH holder and will ensure, in the framework of the Continued Airworthiness, the highest level of safety of the products. The EASA role is strictly limited to CAW oversight.
Moreover, EASA is not bound by the FAA Guidelines 8110-120, regarding FOI. EASA is bound by regulation (EC) 1049/2001 on access to documents, which foresees that any member of the public with residence in the EU (but in practice anyone) can request access to documents held by the Agency. The Agency can then decide whether such access might be granted (there are exceptions foreseen in article 4).
Such regulation applies only to already existing documents that the Agency holds (either because EASA is the author or because they have been received by EASA in the framework of its institutional activities).
This regulation does not apply to request for information where the Agency has to compile a new document to put together the aforementioned requested data and/or info.
Where can I find a list of Supplemental Type Certificates (STC) approved by EASA?
EASA publishes a list of its approved STCs on the EASA website.
The EASA STC list compiles Supplemental Type Certificates issued by EASA since 03/06/2004 and is updated on a weekly basis.
STCs issued before this date or grandfathered STCs are not included in the list.
Why can't I find an STC on the EASA STC List?
The Agency applies its best efforts to ensure completeness of this list.
The EASA STC list compiles Supplemental Type Certificates issued by EASA since 03/06/2004. All EASA STCs are published except:
- 'Grandfathered' STCs issued by the EU Member States prior to 29/09/2003.
- STCs issued by Switzerland (FOCA) prior to 2007
- Recently issued STCs may not yet appear on the list
Should you discover missing data or for any other question, we kindly request you to contact the following mailbox STC [at] easa [dot] europa [dot] eu
What are grandfathered approvals?
Any STC approved or validated by an EASA member state before the establishment of EASA is deemed to be approved under Regulation (EC) No 1702/2003 Article 2a. This covers all previous approvals from Minor Changes to Major Changes, STCs and complete aircraft, both certifications and validations with the exception of products of the former Soviet Union. It also covers the Flight Conditions approved for aircraft operating under national Permits to Fly issued before 28 March 2007.
How do I know whether an STC has been grandfathered?
Any STC approved or validated by an EU member state before the establishment of EASA is deemed to be 'grandfathered' under Regulation 1702/2003 Article 2 (3)(a). Unfortunately, a central repository of such approvals does not yet exist. Please contact the STC holder directly or review the websites of our member states' national aviation authorities.
How do I know whether an FAA / TCCA STC has been validated by EASA?
An STC can be considered to be EASA approved if it satisfies one of the 2 following conditions:
- It has been validated by EASA after the 27 September 2003 (ref. Regulation 1702/2003). In this case, the corresponding validated STC should be published on the EASA website.
- It has been validated by an EASA member state before the 28 September 2003. The Agency does not currently hold a record of all STCs that have been validated by local European National Aviation Authorities before the 28 September 2003.
In any case and in order to verify whether a foreign STC can be considered EASA approved, we suggest that you contact the STC holder.
Should you require the EASA validation of a foreign STC, which does not fulfil any of the two conditions above, please request the STC holder to apply using EASA form FO.CERT.00033 available on the EASA website. Alternatively, you may apply for your own STC using EASA form FO.CERT.00033 but need to demonstrate part 21 eligibility i.e. be a Design Organisation Approval holder if you are an EASA Member State applicant. Alternatively, you may contact a DOA of your choice. If you require further guidance regarding the application process related to the validation of STCs, please contact the following mailbox: stc [at] easa [dot] europa [dot] eu
How can I know if an STC is still valid? How can I know if an STC has been revoked, suspended or surrendered?
EASA certificates are valid unless otherwise revoked, suspended or surrendered. In such cases, a related Certification Information will be published on the EASA website.
If you require confirmation regarding the validity of a particular STC, we kindly suggest that you contact the STC holder.
I am an EU aircraft owner/operator and would like to apply for validation of an FAA STC installed on my aircraft?
EASA has put a new procedure in place to allow EASA member state aircraft owners/operators to apply for the validation of an FAA STC for a single aircraft serial number if certain conditions are met.
The scope of fixed wing aircraft to which this process can be applied is limited to:
- Small Aeroplanes ≤ 5 700 kg MTOW
- Very Light Aeroplane
- Light Sport Aeroplane
- (Powered) Sailplanes
The applicant is required to submit an application form for EASA validation of FAA Supplemental Type Certificate classified as Basic and limited to one serial number(FO.CERT.00134) and to declare that the below conditions are met:
- FAA STC has been installed for a long time with no known continuing airworthiness issues;
- FAA STC holder either not able or not willing to apply for EASA validation;
- A checks against the latest EASA-FAA Technical Implementation Procedures (TIP) provisions confirmed that the FAA STC is classified as “Basic”;
- Confirmation that the applicant has access to design data and instructions for operations and continued airworthiness;
- Acknowledgement of the applicant’s obligations as Holder of the STC in accordance with Part 21, point 21.A.118A
Please note that High Performance Aircraft and any change impacting noise requirements are excluded from this process and is valid only for Fixed Wing aircraft STCs.
The subsequent validation will be limited to a single aircraft serial number to allow the aircraft to be imported and to be issued a Certificate of Airworthiness. This validation is not transferrable to or amendable with another serial number.
EASA will charge this activity in accordance with Commission Regulation (EU) No 319/2014 and the applicable fee is set at one working hour per application.
Download application form FO.CERT.00134 - Application for validation of FAA STC classified as Basic and limited to one s/n
What is the procedure for validations of FAA STCs classified as basic?
A fast track procedure is in place for validations of FAA STCs classified as basic. According to the revision 5 of the Technical Implementation Procedure (TIP), basic STCs are accepted by EASA without further technical review. However, the issuance of the EASA STC can take place only after the FAA STC has been issued and the complete technical data package has been submitted to EASA including the FAA concurrence letter classified as basic.
When do I need to apply for an AMOC approval - and what do I need to do?
All applications for 'Request for acceptance of Alternative Methods of Compliance (AMOC) with Airworthiness Directive (AD)' must be submitted to EASA using EASA Form FO.CAP.00042 duly completed and signed. It should also be noted that every AMOC application request should relate to one AD only. Below you will find the link to the application form as well as to additional information regarding AMOC.
How can I find out if I need to apply for “Forwarding Letter only - without need for technical support” or for “Full EASA Validation Support - with need for technical support”?
Please send an email to Validation [dot] Support [at] easa [dot] europa [dot] eu. We will investigate and confirm if you need to apply for Category 1 or Category 2:
“Forwarding Letter only”: For third countries that have neither a Bilateral Agreement nor a Working Arrangement with EASA in place.
“Full EASA Validation Support”: For third countries that have a Bilateral Agreement and/or Working Arrangement with EASA in place, i.e. USA, Canada, Brazil, China, Japan, and Russia.
What is a financial estimate?
The financial estimate is for information purposes only and is not mandatory for the applicant and aims at increasing the transparency on costs before the project starts.
It is a first estimation of working hours given by the technical section, before starting the technical investigation. The financial estimate is provided to the applicant upon request and only once the financial estimate is confirmed by the applicant an EASA Project will be created.
In case the foreseen working hours are not sufficient, the financial estimate may be revised and submitted to the applicant for acceptance. Please note that financial estimates are valid 3 months only.
The validating authority is asking for a re-classification to Category 2. What do I need to do?
In case the technical investigation is more complex than foreseen in the beginning, the validating authority may ask for a re-classification from Category 1 to Category 2. In order to reflect this re-classification in our EASA system also for invoicing purposes, we would need your active involvement and kindly ask you to submit a revised EASA form FO.CSERV.00041 to Validation [dot] Support [at] easa [dot] europa [dot] eu. On the 3rd page, please delete box 5.2.2 and replace it by box 5.2.3.
Which types of approvals can be validated in Third Countries?
The following approvals can be validated in Third Countries: Type Certificates (TC), Major Changes, STCs, AFMs and ETSOAs (European Technical Standard Order). Please send an application to Validation [dot] Support [at] easa [dot] europa [dot] eu.
ETSO-Applications please send to ETSOA [at] easa [dot] europa [dot] eu.
Approvals may be validated in third countries with which EASA has no Bilateral Agreement and/or Working Arrangement with EASA (category 1) or in third countries having a Bilateral Agreement and/or Working Arrangement with EASA (category 2)
Please also refer to the question on category 1 or 2.
I would like to apply for Certification Support for Validation in Third Countries – what do I need to do?
You need to fill in the EASA form FO.CERT.00041 which can be found here.
There are two different scenarios:
Forwarding Letter only - without need for technical support (category 1): Your EASA approval and related documents will be only forwarded together with an EASA Forwarding Letter to the validating authority. There is no technical support foreseen. This EASA service is free of charge.
Full EASA Validation Support - with need for technical support (category 2): Your EASA approval will be forwarded to the responsible technical section. An EASA PCM will be allocated your task and will prepare the EASA Forwarding Letter. The Applicant Services Department will then submit the EASA Forwarding letter and its related documents to the validating authority. This EASA Service is charged on an hourly rate. Please consult the EASA fees and charges regulation Commission Regulation No 319/2014 for the applicable hourly rate. A financial estimate may be requested at submission of your application and prior commencement of work.

What does the Rotorcraft MTOW 50% rule mean?
For all post-TC design applications the applicable F&C category is based on the type level and corresponds to that category in which more or equal to 50% of the models are within a given type.
This change was introduced by the EASA F&C regulation (Commission Regulation (EU) 319/2014) as of April 2014 and changed the previously applicable rule that the highest weight category was applicable, even though it might have been only connected to one of the models.
In accordance with PART V/Explanatory Note (4) of EASA F&C regulation, the MTOW of the initial TC and subsequently of the majority of the related models covered by this Type Certificate (i.e. more than 50 %) determines the applicable MTOW category.
Should the number of models in both the higher and the lower MTOW categories being equal, the higher MTOW category applies. Once the MTOW category has been determined at the product type level, it is to be consequently applicable for all related applications, e.g. for minor changes, STCs, etc.
Why is my small rotorcraft charged as medium rotorcraft under F&C?
Commission Regulation (EU) No. 319/2014 establishes the EASA Fees and Charges and defines in Part V point (2) the following categories of Rotorcraft Products for this purpose (only):
- Large Rotorcraft refers to CS 29 and CS 27 cat A;
- Small Rotorcraft refers to CS 27 with Maximum Take Off Weight (MTOW) below 3 175 Kg and limited to 4 seats, including pilot;
- Medium Rotorcraft refers to other CS 27
According to EASA TCDS R.008, the AS350 rotorcraft is a CS27 rotorcraft with MTOW below 3 175kg and a seating capacity of 6, including the pilot. Hence it must be classified as Medium Rotorcraft as per the above definition.
According to EASA TCDS R.146, the AS355 rotorcraft is a CS27 rotorcraft with MTOW below 3 175kg and a seating capacity of 6 (or 7, if an optional two-place seat is installed), including the pilot. Hence it shall be classified as Medium Rotorcraft as per the above definition.
See in particular the EASA Product List – Rotorcraft.
What is the status of my project?
If you wish to enquire about the status of your project, please contact directly your project certification manager (PCM) by quoting the EASA project number. The contact details of the PCM are sent to you with the EASA Acceptance Letter once your project has been allocated.
Alternatively you may send an email to new [dot] applications [at] easa [dot] europa [dot] eu
My project is re-classified, what implications are there?
Fees & charges category re-classification
Your project may be reclassified to a higher or lower category, e.g. from Simple to Standard, based on certain criteria that are defined in Commission Regulation (EU) No 319/2014. As a re-classification to a higher category leads to a higher fee, we will contact you first for your acceptance before taking any further action.
In case of re-classifications to a lower category, a credit note will be issued, if applicable.
For further information on the different fees & charges categories, please consult the tables sorted by application type provided in the Annex of the fees and charges regulation Commission Regulation (EU) No 319/2014.

I want to apply for approval of flight conditions - what do I need to do? I want to apply for Permit to Fly - what do I need to do?
The European Aviation Safety Agency (EASA) is responsible for the approval of flight conditions. Such an approval is the basis on which a Permit to Fly (PtF) can be issued by the Competent Authority of the State of Registry, or of the State prescribing the identification marks of an aircraft.
A PtF is generally issued when a certificate of airworthiness is temporarily invalid, or when a certificate of airworthiness cannot be granted, but the aircraft is nevertheless capable of performing a safe flight.
Please use EASA Form FO.CERT.00037 (with EASA Form 18B in the annex) to apply for approval of flight conditions at EASA. With the approved flight conditions (EASA Form 18B) you can apply for a Permit to Fly at the local national aviation authority the aircraft is registered.
More information can be found in the fact sheet on Permit to Fly which is published on the EASA website. Please click here.
