Exactly backwards actually. While there have been a few pre 1966 V-Tails and Debs reported to have a spar web crack, most of the cracks ha...
exactly the opposite. The short body jobs almost never need the doubler.
F33As past serial number CE-1192 (~1987/88 model year) are NOT affected by the spar AD. Beech finally made the structural changes required to account for the heavier aircraft. Yes, they are heavier than the earlier aircraft, but they also have a better autopilot, zinc-chromate as standard, more sound insulation and a better interior than the old models.
In my opinion, if you dont need the payload of an old model and you dont need the room of an A36, a '87-'94 F33A with a IO550 conversion and updated avionics is probably one of the best personal aicraft there is. Very few were made in those years and the prices paid reflect the value.
