Aircraft Accident/Incident Report

Delta Junction, Alaska 99737
Sunday, April 29, 2007 13:00 AKD

NTSB Narrative Summary Released at Completion of Accident

The pilot was conducting off airport landings in a tundra-tire equipped airplane under Title 14, CFR Part 91. During a telephone conversation with the National Transportation Safety Board investigator-in-charge on April 30, the pilot reported he had flown the airplane for about an hour since his previous off airport landing. He said when he touched down, unknown to him, his right main landing gear tire was flat, and due to its large size, he was unable to maintain directional control on the ground. The airplane exited the intended landing area into rough and uneven terrain. He reported airplane nosed over, and the left wing lift-strut was bent. The pilot said when he examined the deflated tire he found a stick imbedded in the tire, which he believes was from his previous landing.

NTSB Probable Cause Narrative

The damaged and deflated over-sized tire on the main landing gear, which precipitated a loss of directional control during landing.
