ED Decision 2015/016/R

CS for Standard Changes and Standard Repairs (CS-STAN) – Phase 1

This Decision addresses a proportionality issue: it will allow a simpler process for the design and embodiment of some changes and repairs when applicable to certain aircraft (aeroplanes up to 5 700 kg MTOM, rotorcraft up to 3 175 kg MTOM, most sailplanes, balloons and airships).

The concept of Standard Changes and Standard Repairs was introduced with Regulation (EU) No 748/2012 (21A.90B and 21A.431B). In order to use these concepts, the establishment of the related Certification Specifications (CS-STAN) was required by EASA. The package now released (Phase 1) contains a first Decision on Certification Specifications CS-STAN with additional AMCs to Part M, mainly.

In the future, CS-STAN will be further supplemented (Phase 2) based on lessons learned during Phase 1 and with new proposals provided by the affected stakeholders.

The proposed changes are expected to reduce the regulatory burden for the embodiment of simple changes and repairs in/on certain aircraft when fulfilling the acceptable methods, techniques and practices included in CS-STAN. It is expected that this will have a positive impact on the operation of the affected aircraft in Europe, thus promoting General Aviation (GA). Additionally, a simplified procedure for the embodiment of Standard Changes and Standard Repairs could limit the illegal practices of some owners that have not followed the applicable rules when modifying the aircraft and encourage the installation of safety equipment.
