Aircraft Accident/Incident Report
Evanston, Wyoming 82930
Tuesady, June 10, 2008 10:30 MDT
NTSB Narrative Summary Released at Completion of Accident
The pilot reported that he extended the landing gear while on approach for landing and got a "gear unsafe" red light indication. He recycled the landing gear and the gear light went out. The pilot called the local fixed base operator on the field and requested a flyby to confirm that the landing gear was down. Ground personnel indicated that the gear appeared to be down. The pilot accomplished the final pre-landing checks and landed the airplane. The landing gear collapsed immediately after touchdown. Postaccident examination of the airplane by a mechanic revealed that two wing skins and a metal tubular former in the belly needed to be replaced. The mechanic who inspected the landing gear stated that the gear collapsed because the over center tension for the nose wheel landing gear down locks was not properly adjusted.
NTSB Probable Cause Narrative
A collapse of the landing gear due to improper maintenance.
