EASA has published a Notice of Proposed Amendment to its Certification Specifications for Standard Changes & Standard Repairs (CS-STAN) that is intended to allow a simpler process for the design and embodiment of some changes and repairs when applicable to certain aircraft (airplanes up to 12,500 pounds MTOM, rotorcraft up to 7,000 pounds MTOM, and most sailplanes, balloons and airships).

The concept of Standard Changes and Standard Repairs was introduced with Regulation (EU) No. 748/2012 (paragraphs 21A.90B and 21A.431B). In order to use these concepts, the establishment of the related Certification Specifications (CS-STAN) by the European Aviation Safety Agency was required.

This NPA contains a first proposal (phase 1) on CS-STAN. In the future, CS-STAN could be enlarged based on experience and with new proposals provided by affected stakeholders (phase 2).

The proposed changes are expected to reduce the regulatory burden for the embodiment of simple changes and repairs in certain aircraft when fulfilling the acceptable methods, techniques and practices included in CS-STAN. It is expected this will have a positive impact on the operation of the affected aircraft in Europe, promoting general aviation. Additionally, the existence of 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 may encourage the installation of safety equipment.

Comments must be received by January 6, 2015.
