Aircraft Accident/Incident Report

Nampa, Idaho 83687
Wednesday, August 20, 2003 12:30 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that he verified that he had a three green indication for the landing gear prior to touch down. During the landing roll, and having decelerated to about 10 miles per hour, the right main landing gear began to collapse. As the aircraft departed the right side of the runway, it impacted a runway light. The nose gear collapsed and the propeller struck the ground. During a post-accident inspection of the landing gear system, no evidence of a mechanical failure or malfunction was found.

NTSB Probable Cause Narrative

Landing gear collapse for undetermined reasons during the landing roll. On ground collision with a runway light was a factor.
