Hello
I was offered to make a research and analysis for AW139 avionic systems reliability as my thesis due to the reason that some operators have weird avionic problems with this certain chopter. For example blinking displays, windshield heater malfunctioning, sx16 searchlight malfunction, some kind of problems with MAU and NIC, external power CB popping out, weird CAS messages during flight etc. I have helped to fix some of problems and many more on a few AW139's (except the "problems" that Agusta claims not to be a problem at all
).
I would appreciate if you could tell what kind of problems have you came across associated avionics (both in the air or on the ground). If here is anybody who is an avionic then I would like to know if it's common for this specific chopter that wiring diagrams don't match with the aircraft.
If anybody knows somebody who I could directly discuss this subject with (in maintenance field) I would be greatful. Somehow I couldn't find anybody's contacts in the web who works in maintenance although I have found at least a hundred operators.
So far I have managed to gather detailed history for only a few AW139's but I hope get some more information about them.
Thank you and have safe flight.
