Good to know

An AMOC application should relate to one AD only.

Before applying, please check if you meet the following requirements for automatic acceptance:

According to TIP 4.4.2.2 an FAA AMOC to an FAA AD is automatically accepted when

  1. The AD was issued against a US approved design and EASA has adopted the AD
  2. The AMOC was issued to a US design change approval holder
  3. Compliance to the AD is affected by the design change approval
  4. The intent of the AMOC is to provide the necessary adaptation to the AD compliance method

A typical example is that of an STC holder of a Freighter Conversion that requires an AMOC for the modified aircraft for ADs applicable to the baseline aircraft. 
In line with the agreed interpretation of TIP 4.4.2.2., the AD is applicable to aircraft converted by the STC, and AMOCs issued to the US STC holder can be considered to fulfil the conditions of para 4.4.2.2 and be automatically accepted when they aim at adapting the method of compliance to the AD for the modified aircraft.
If you have any questions related to this interpretation you are welcome to contact the Agency through our general AD enquiry e-mail address adsupport [at] easa.europa.eu

Fees and Charges: In accordance with Commission Implementing Regulation (EU) 2019/2153, the Agency levies fees and charges for all its certification and approval activities. The applicable table for your application can be found in Part II of the regulation.
