Aircraft Accident/Incident Report
Lapeer, Michigan 48446
Tuesady, May 21, 2013 14:00 EDT
NTSB Narrative Summary Released at Completion of Accident
The pilot was conducting a postmaintenance test flight with the owner acting as copilot. During the landing roll, the pilot’s seat came loose and slid full aft. The right wing came up while the pilot’s hand was still on the flight controls. He instructed the copilot to take the controls and keep the airplane on the runway. The left wingtip and aileron sustained minor damage during the incident sequence; however, the damage was not discovered until 3 weeks after the incident. An examination of the seat-latching mechanism revealed that the metal rod that locked the seat in place was bent. When aft pressure was applied to the seat, the bent rod released from the latch hole in the seat track, which allowed the seat to slide.
NTSB Probable Cause Narrative
The malfunction of the pilot’s seat-latching mechanism due to a bent rod, which allowed the seat to come loose and slide full aft and resulted in a temporary loss of airplane control.
