I work for a large european aircraft manufacturer (part 145 organisation) and we are having some lively debate on regulations
If I recieve an assembly, for instance a brake maniolfd from a manufacturer with its corresponding EASA form 1
I then fit said assy onto an aircraft and find that a componant malfunctions, lets say a servo valve. I then trouble shoot and diagnose a faulty servo valve on said assy.
If I change that componant, do I then invalidate the EASA form 1, requiring the assy to be replaced?
Please bear in mid that this is not part 21 organisation further the aircraft maintenance manual lists the componant as a replacable part with a procedure to do so.
