Analysis

The airplane was being operated by the commercial certificated pilot as a visual flight rules (VFR) personal cross-country flight under Title 14, CFR Part 91. During an off airport landing on a gravel airstrip the left main landing gear collapsed. The pilot said an inspection of the gear revealed that the landing gear attaching bolts had sheared, and that the left wing and stabilator were damaged when they struck the ground. He said there were no mechanical anomalies with the airplane prior to the accident. Due to the remote location, the NTSB did not examine the airplane.

Factual narrative

On May 19, 2007, about 1030 Alaska daylight time, a Piper PA-32 airplane, N4025W, sustained substantial damage when its left main landing gear collapsed during landing on a gravel airstrip, about 21 miles west of Kenai, Alaska.

The flight departed the Palmer Municipal Airport, Palmer, Alaska, about 0915.

During a telephone conversation with the National Transportation Safety Board (NTSB investigator-in-charge (IIC) on May 20, the pilot said when the airplane touched down on the gravel airstrip the left main landing gear collapsed.
