Aircraft Accident/Incident Report

Salina, Kansas 67401
Tuesady, August 15, 1995 9:30 CDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that the flight entered into a light overcast layer and light rime ice began to accumulate on the windshield and leading edge of the wing. He turned on the deicing heat to the windshield, pitot tube, vents, and propeller. Approximately one-half hour later, the airplane suddenly began to shudder and buffet. The pilot stated that the airspeed then began to decrease, and he assumed the pitot tube was block. After he advised air traffic control of a problem and requested a lower altitude, the airplane rolled to the left and entered into a spin. The pilot was able to regain control of the airplane after losing 5,000 feet altitude and landed at the nearest airport. The airframe sustained substantial structural damage during the recovery. The pilot stated the flight 'entered area with increased ice accumulation and [I] didn't notice.'

NTSB Probable Cause Narrative

the pilot's inattentiveness to the severity of the weather conditions, and his failure to maintain airspeed. Factors in the accident were: the icing conditions, airframe ice accumulation, and the design stress limits of the airplane being exceeded by the pilot during recovery.
