Loss of VH-RMI
Fantome, if your post alluded to my previous we are looking at two different accidents. Below the "Copy and Paste" from the notes of Frank Yeend, one of the Accident Investigators into the loss of VH-RMI.
"In the latter stages of the flight, the fire and smoke on the port side of the aircraft became visible from the cabin, but by this time the softening of the wing spar would have progressed to the point where a catastrophic failure was imminent.
The attachment of the No. 2 blower oil metering unit was effected by 5 threaded studs in the body of the unit upon which five castellated nuts held secure a cover plate. In turn, these castellated nuts are secured by a copper locking, wire passing through each to prevent unwanted rotation of the nuts or the studs. In the wreckage examination only one stud remained and none of the nuts, but obviously there was a strong presumption that, although there was a severe vibration set up by the blower lobe failure, the loss of the studs and nuts probably occurred because the required locking wire had not been put in place during the last overhaul of the blower".
