Question for Paul McBride, the General Aviation News engines expert: I have been maintaining a 1953 T-34 (Beech A45) with a Continental O-470-13 engine installed (original) for the last couple of years. The ownership group has been reporting a loss of propeller control after about 20 to 30 minutes into their flight, however it was happening intermittently and now it is happening almost every flight.
