due to the organization which had prior custody of the aircraft not carrying out a mandatory inspection before hand-over which would have discovered a stabilator spar crack
A long time ago and the memory may be a tad deficient .. I don't recall that that was the case (a good mate did the last inspection prior and he was a bit of a stickler for detail) and, if my recollection be correct, there was a subsequent inspection which was deferred ?
djpil's recollections may be better than mine ...
