Narrative:About five minutes after takeoff, at 6,500 feet, the 1947 model airplane was cruising at 160 to 165 knots, when it encountered turbulence and experienced an airframe vibration. The pilot reduced airspeed, which eliminated the vibration, then he landed without further incident. Subsequent examination revealed that the fuselage station 256.9 bulkhead, located directly below the leading edge of the V-tail, was cracked at all four corners. Further investigation revealed that the airplane's ruddervators had been removed in 1995 for reskinning due to corrosion. Reskinning was accomplished with Beech factory replacement skins, and the ruddervators were then painted with several layers of paint. This necessitated the installation of an additional one-pound (lead) weight on the outboard tip of each ruddervator to achieve correct control surface balance. Also, the pilot stated that he could not be sure whether the station 256.9 bulkhead was damaged in flight, or when the ruddervator contacted a hangar support beam as the airplane was being pushed in a hangar.
Probable Cause: failure (cracking) of the aft fuselage bulkhead for undetermined reason(s).
