Thanks Rb,
For Rotor craft EASA made this as a MAJOR mod, But there is no reference for small Aircraft. It is very old aircraft so no reference in Certification basis. I Think the go fwd is to discuss with EASA.
HI,
My company is doing a Cockpit and Flight Data Recorder Installation of a FAR/CS 23 Airplane.I couldn't find any EASA guidance on this Classification to determine this as a MAJOR or MINOR mod.
Many Thanks
