Minchumina Airport
Aircraft Accident/Incident Report
Lake Minchumina, Alaska 99575
Monday, July 2, 2001 8:50 AKD
NTSB Narrative Summary Released at Completion of Accident
The crew of the arriving cargo flight flew over the airport to inspect the runway conditions, and subsequently elected to use runway 20, a 4,200 feet long, 90 feet wide, gravel runway. The crew noted that the runway surface had a number of frost-heaves that had developed during the past winter. During the initial landing touchdown, the airplane "skipped" as the main wheels touched on the crest of one of the frost-heaves. The airplane became airborne, floated slightly, touched again about 750 feet beyond the approach end of the runway. During the second landing flare, the main landing gear wheels touched on the downhill side of a second frost-heave, which allowed the tail of the airplane to contact the gravel runway. The captain characterized the second touchdown as within acceptable limits, but with a slightly nose high attitude. A postflight inspection by the crew discovered a 4 feet by 2 feet puncture on the belly of the airplane, just forward of the main cargo door.
NTSB Probable Cause Narrative
The flight crew's improper recovery from a bounced landing. Factors associated with the accident were the selection of an unsuitable landing area, and a rough/uneven landing surface.
