It is very important that inspectors observe the requirements diligently and note it is a signed requirement on the BGA GMS (267 task 35). The design code CS-22 specifies the colour but does not state a shade. It is possible that this had been interpreted too liberally. Dark Blue for air brakes and Dark Green for trimmer are not acceptable and also add to confusion when next to a black landing gear retract/extend handle. The colours must be bright and easily identifiable in poor light. 8 Buying and Selling Sailplanes The BGA has published revised and expanded guidance on what to do when buying and selling your aircraft taking into account the changed EASA requirements. http://www.gliding.co.uk/bgainfo/technical/documents/buyingselling.pdf Compliance Statement: All mandatory inspections and modifications have been included up to the following: CAA CAP 455 Airworthiness Notices, Version September 2009 CAA CAP 747 Mandatory Requirements for Aircraft, issue: 3 amendment: 2010/06 State of Design Airworthiness Directives review date: 23 December 2010 For reference: FAA Summary of Airworthiness Directives.
