Well I said I was always in failure escape mode and today the old Beaver suddenly dropped from 2200rpm after toff to 1900rpm and I noticed it at max gross. Climbed straight ahead along the river just in case the floats needed to get wet suddenly and made sure I had plenty of room between me and the ground before making my turn over land.
It certainly can happen at any time but I fly expecting it so like today, no great shock. Meant a landing and cowls off to sort out the problem which turned out to be quite minor. But bobbing around in the sea trying to remove cowls etc is not fun!
