FAQ n.22058

What is the EASA administrative validation of the FAA Basic STCs for second hand aircraft, serial number specific?


This is a simplification of the EASA validation process for the cases where the US STC Holder of a FAA STC classified as Basic is unwilling or unable to apply for EASA validation.

The scope is limited to the following product categories and installed engines, if applicable:

  • Aeroplanes ≤ 5 700 kg MTOW
  • Very Light Aeroplanes
  • Light Sport Aeroplanes
  • Powered Sailplanes
  • Sailplanes
  • ELA 1 Balloons or Airships
  • ELA 2 Balloons or Airships
  • Small Rotorcraft (i.e. Part 27 aircraft with MTOW ≤ 3 175 Kg and limited to 4 seats, including pilot)
  • Very Light Rotorcraft

Please note that STCs that involve changes which impact the aircraft’s noise characteristics are excluded from this simplified process.

Please note that High Performance aircraft and commuter are excluded from this simplified process as well as external installations STCs applicable to VLR or Small Rotorcraft.
