According to the pilot, the airplane was traveling approximately 180 mph, at 2300 rpm and 20-23 inches of manifold pressure (mp), in a wings level descent. While descending through 2,500 feet, the pilot felt a minor vibration in the yoke and rudder pedals, which persisted between three and five seconds. The pilot reduced power (approximately two or three inches of mp), the airplane decelerated to 160 mph and the vibration ceased. The airplane's never exceed airspeed (Vne) is 202 mph, and the maximum cruise speed (Vno) is 176 mph. Examination of the airplane revealed that the aft fuselage sustained damage between the FS 233.5 and FS 256.9 bulkheads. The lower longerons were buckled. The belly skin located at FS 256.9 bulkhead was separated from the fuselage. The damage was consistent with symmetric downward overload. The ruddervators were checked and determined to be properly balanced.
