I have been following this with interest. IIRC the 330 gearbox mounting is the same as the early 332 before the strut. In 1978 we used to, and I believe they still do, wrack our Pumas around Northern Norway in the middle of solid high pressure systems at minus 26 degrees. We lost a Puma at Bodo in an in-flight break up with three fatalities. The reason was put down to a main door detaching and colliding with the tail rotor plus all that entails. The door concerned was suspect before the accident but one wonders whether a divergent ocsillation was ever set up which may have caused the door to detach.
