From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23) During landing roll the aircraft bounced hard over ruts in the dirt airstrip. The pilots seat slid back causing the pilot to lose control of the aircraft. The aircraft veered left off of the strip. Left wing tip struck a tree branch and the aircraft ground looped into the trees snapping off the right main gear and crushing the right wing. (.4) according to the pilot, as the airplane accelerated for the takeoff, the landing gear rolled over a rut in the runway surface and the airplane bounced. When the airplane bounced, the pilot reported that his seat moved rearward, he could not reach the flight controls, and he lost control of the airplane. The airplane veered off the left side of the runway and collided with trees. An examination of the runway surface revealed that the clay and gravel runway had ruts in the center of the takeoff area. The examination of the airplane seat assembly revealed that both the seat rails and the seat locking pins were in serviceable condition.
