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.

The first pilot, seated in the front seat of the public use airplane, was banking the airplane to the left while flying in close proximity to the ground over an open field in pursuit of running coyote. The first pilot was in the second phase of an agency training program. The second pilot, acting as a part time instructor pilot/gunner and seated in the rear seat, was pointing a shotgun outside the airplane in an attempt to kill the coyote as per the agencys aerial hunting program. The airplane aerodynamically stalled during the maneuver and entered an uncontrolled descent. It impacted the ground in a near vertical inverted altitude and was destroyed. An examination of the airframe and engine did not reveal any evidence of preimpact mechanical malfunctions. The airplane was about 75 punds over its published maximum gross weight, and the density altitude was about 6500 feet during the accident. Unapproved modificaitons to the airplane and inadequate maintenance record keeping by the operator were found during the investigation. The second pilots throttle handle was not installed in the throttle control at the time of the accident.
