CRD 2014-24

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

This rulemaking activity 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) and when in compliance with CS-STAN.

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 Agency had to publish the related Certification Specifications (CS-STAN). The package now released is the first phase of this rulemaking activity (see ToR RMT.0245 (MDM.048) Issue 2) and contains a first Decision for the initial issue of CS-STAN with additional AMCs, mainly to Part-M.

In the future, CS-STAN will be further supplemented (Phase 2).based on experience 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 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. Additionally, a simplified procedure for the embodiment of Standard Changes and Standard Repairs could limit the illegal practices of some owners who have not followed the applicable rules when modifying the aircraft and may encourage the installation of safety equipment.

This CRD contains the comments received on NPA 2014-24 (published on 6 October 2014) and the responses provided thereto by the Agency.

Based on the comments and responses, Decision 2015/016/R was developed.
