One single safety authorisation valid in 32 EASA Member States, including the United Kingdom which remains a member state with all the rights and obligations set out in the treaties and under EU law.
Europe has centralised the process to authorise third-country (non-EU) operators performing commercial air transport operations into the EU, thereby replacing various schemes of the EASA Member States previously in place. Instead, a single safety authorisation is issued centrally by the European Union Aviation Safety Agency (EASA). The TCO application form can be found here.
The European Parliament and the Council tasked EASA to manage a single European system for vetting the safety performance of foreign air carriers. In doing so, EASA issues safety authorisations to foreign air carriers when satisfied that they comply with minimum international (ICAO) safety standards and applicable airspace user requirements in EU airspace.
Applicability of Part-TCO
Any third-country operator that intends to perform commercial air transport (CAT) operations into, within or out of any of the following territories requires a TCO authorisation issued by EASA:
- the Member States of the European Union
- the 4 EFTA States (Iceland, Liechtenstein, Norway and Switzerland)
- the following territories in which Regulation (EU) 2018/1139, the so called “Basic Regulation” applies: Gibraltar, Åland Islands, Azores, Madeira, Canary Islands, Guadeloupe, French Guiana, Martinique, Réunion, Saint-Martin, Mayotte
A TCO authorisation is not required for operators only overflying the abovementioned territories without intended landing.
One-Off notification flights
A regulatory provision (TCO.305 Non-scheduled flights – one off notification) is available to allow certain flights to be operated without a TCO Authorisation. This provision is solely applicable to the following cases:
- air ambulance flights, and
- non-scheduled flights “to overcome an unforeseen, immediate and urgent operational need”. Such flights should be performed in the public interest and where the urgency of the mission justifies by-passing the regular TCO assessment process, e.g.humanitarian missions or disaster relief operations.
EASA employs a risk-based approach for TCO assessments in that credible data sources are continuously being analysed. The lower EASA’s confidence in a foreign operator’s safety performance or the less credible data available for an operator or the State in which the operator is certified, the more comprehensive the assessment. For operators with high confidence level, a simple and fast desktop review of completed questionnaires and material evidence is sufficient, whereas operators with lowered confidence levels will be assessed more diligently. Where necessary, EASA will invite operators for a technical meeting in Cologne, or EASA will request to perform a TCO audit on site.
Following its TCO assessment, EASA validates the foreign Air Operator Certificate (AOC) by issuing an EASA TCO Authorisation accompanied by Technical Specifications, setting out the scope of operations authorised in the EU. The status of authorised aircraft is reflected in a dedicated electronic publication (TCO web-interface).
The TCO Authorisation process consists of three distinct phases: Application, Evaluation, Authorisation. All TCO Authorisation holders are subject to EASA continuous monitoring of their safety performance, which includes periodic file reviews. A dedicated web-based software application supports communications between EASA and the operator.
For the vast majority of Third Country Operators (TCOs), the process to obtain an EASA TCO Authorisation is entirely free of charge. According to the criteria set in the TCO Regulation and following a risk based approach, EASA may decide to organize technical meetings and on-site visits as part of the process. In this case a flat fee applies.
The EU "Air Safety List"
The EU Air Safety List mechanism pursuant to Regulation (EC) No 2111/2005 is governed by the European Commission in Brussels. EASA and the European Commission ensure that both instruments are closely coordinated. Notwithstanding, air carriers subject to a ban or operating restriction under the EU Air Safety List mechanism remain eligible to apply to EASA for an assessment under Part-TCO.
A section containing Frequently Asked Questions and additional information is available to stakeholders.
Commission Regulation (EU) No. 452/2014 as amended by Regulation (EU) 2016/1168 lays down technical requirements and administrative procedures related to air operations of third country operators. Annex 1 (Part-TCO) contains the requirements for the operator, while the authority requirements regarding the authorisation of foreign operators are laid down in Annex 2 (Part-ART).
EASA has published associated Acceptable Means of Compliance (AMC) and Guidance Material (GM). This document is available in the document library (Part-TCO/ AMC/GM) of our website.
How third-country operators should apply
- Study the Commission Regulation (EU) No. 452/2014 and Acceptable Means of Compliance (AMC) and Guidance Material (GM).
