Just a spotter,
WAnt to pull you up on your reasons for the crash of EI-AOF June 22, 1967. This was, of course, the Aer Lingus Viscount on a training flight.
"The accident report blamed corrision around the tail and higlighted issues with the then Aer Lingus maintenance procuedures."
According to my source on this crash, Michael O'Toole's excellent book on Irish air crashes, Cleared for Disaster, the probable cause was the possible incapacitation of the training captain, the only qualified pilot aboard, perhaps due to a heart attack, and the inability of the trainees to find the airport in the overcast conditions, and to land the airplane. The main safety recommendation was that a second qualified pilot should always accompany the training captain.
I know corrosion was examined in the Tuskar Rock crash (the subject of this thread) but this has always been an inconclusive investigation.
