Aircraft Accident/Incident Report
Chevak, Alaska 99563
Tuesady, January 12, 1999 10:50 AST
NTSB Narrative Summary Released at Completion of Accident
The certificated commercial pilot reported that during his initial descent to the Chevak Airport, the airplane became 'heavy to control' while flying through snow showers mixed with rain. He stated that while on a left base for landing on runway 14, the airplane failed to respond to left control yoke movements. He said that he was able to turn the airplane slowly to the right, 270 degrees from his original heading, and align the airplane for landing on runway 14. He stated that while on short final over the threshold of the runway, he again applied left control yoke movement to correct for a 12 to 15 knot, left crosswind. The control movement again failed to have any effect, and the airplane drifted to the right, touched down to the right of the runway, and nosed over. The pilot stated that a postaccident inspection revealed ice formation on the airplane's wings, struts, and fuselage. The airplane sustained substantial damage to the wings and fuselage.
NTSB Probable Cause Narrative
The pilot's continued flight into adverse weather conditions. Factors associated with the accident were freezing rain, an accumulation of ice on the wings and ailerons, and diminished directional control.
