HC - Hi. The latest AAIB report says that no EC225 shaft had covered 4000 hours and that the shaft fitted to CHC's machine had 3800 or so. (sorry don't have the report to hand to give exact number). So on the basis nothing has got to 4000 and the one in the sea in October was 3800...
One thing I find incredible with story is how some of these odd decisions are almost accepted.
You have some guy fly a Gazelle into a hill or some private owner suggest a new crazy scheme and everyone scoffs or calls everyone involved stupid etc.
Yet here you have one of the biggest manufacturers make at best questionable decisions with so far little insight to what testing has been done and the silence is deafening. I mean the latest AAIB report suggests part of the ongoing investigation is around the suitability of the material selected.. Really?!
