What happened
On September 24, 2011, a Beech 36, registration N7549N, was involved in a landing gear collapse at Riverton, Wyoming. Following the completion of the landing, the pilot accidentally moved the main landing gear lever to the retract position instead of the flap lever. This action caused all three landing gear components to collapse, resulting in substantial damage to the aircraft's undercarriage. There were no injuries resulting from the incident.
The investigation
The investigation reviewed the pilot's account of the event. The pilot reported that the aircraft was operating normally prior to the incident and that no mechanical anomalies were present that would have prevented normal operation.
