Tiivistelmä
In 2020, a Finnish aircraft manufacturer Atol Avion Ltd started working on a modification project considering certain Cessna 150 aircraft models. These modifications had to be approved by the European Aviation Safety Agency, EASA.
The purpose of this thesis was to study the fundamental aircraft type certification authorities and processes, and in addition, to describe guidelines on how to proceed with the application process itself. The information would be used to advance the Atol Avion project. This thesis was conducted partly as a literaturebased study and partly as a documentation of an engineering project.
The basics of aircraft type certification, along with respective terms, are explained in this thesis. EASA Part 21, an annex of European aviation law focusing on aircraft type certification, is heavily featured. Methods regarding how to comply with EASA regulations are also addressed.
The information gathered for this thesis was successfully used during the supplemental type certificate application of Atol Avion’s modification project. Therefore, it could also be used to help other small engineering organisations to achieve type certification for their aircraft or aircraft-related parts. The Cessna project of the company is used as an example throughout the thesis, naturally pushing its focus towards general aviation aircraft.
