Hey Helldog....let me know...by PM if you wish......what the failure actually was, Ive been speaking to a couple of PT6 spanner monkeys and they all have different opinions...the smart money is on the compressor turbine making mischief..and fouling up the gearbox works etc.... They are also scratching their heads as all 3 of them reckon this kind of failure shouldnt happen without clear maintenance indications before hand.
Let me know when you know
Cheers
