Aircraft Accident/Incident Report

Davis, West Virginia 26260
Tuesady, May 12, 1998 10:57 EDT

NTSB Narrative Summary Released at Completion of Accident

The airplane was cruising on a southerly heading at 13,000 feet, in instrument meteorological conditions, when, over a 23-second period, it turned toward the west, descended about 1,200 feet, then broke up. The last 3-point smoothed ground speed calculation for the airplane indicated 242 knots. Winds aloft were from the east, about 10 knots. The airplane's maximum operating speed was 167 knots indicated, and maximum maneuvering speed was 141 knots indicated. At the time of the accident, the airplane was in conditions conducive to icing. The airframe anti-icing system was inoperative, and it was undetermined whether the engine and pitot ice protection systems had been activated. The horizontal stabilizer and the wings exhibited markings consistent with downward overstress separation. The flight originated from Hamilton, Ontario, and stopped at Buffalo, New York, before continuing. An AIRMET, calling for icing, was in effect, but not mentioned during the Ontario weather briefing. In Buffalo, no flight service station services were requested or provided. Flight into icing conditions in the accident airplane was prohibited, and the procedure was to turn back or change altitude to escape the icing.

NTSB Probable Cause Narrative

The pilot's spatial disorientation, his subsequent loss of control of the airplane, and his overload of the horizontal stabilizer during a recovery attempt. Factors include the pilot's continued flight into icing conditions, his lack of airspeed control, and the lack of an AIRMET advisory from the weather briefer.
