A/C 7 showed no signs of wear on the splines - and we're over 100 hours even on ours.
There was bound to be a few teething troubles. I was in at the start of the 332 in Aberdeen with BHL in the early 80s. The first couple of Tigers seemed to have a large number of MGB changes. We won't dive too far into the very close call of a spindle nearly letting go a blade on the NW Hutton - well done to that crew.
Lets go easy on the verbal sparring and wait for the facts to come out along with the fix which will no doubt appear very soon.
