blackburn,
Yes, that is correct, found the right log book, it was indeed BSL. Have to agree with your findings of Ken, a real gentleman. Those PA22's were really built to last!!
Last time I heard of Ken, heard through the grapevine many years ago, he was P1 on a Air Pacific BAC1-11 that had an explosive decompression between Nandi and Auckland. Cant remember the details, maybe some one in the forum can recall.
