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) Untermeyer stated that he completed an IFR flight from kpne and was downwind on a visual approach for runway 24 at mvy. He reported that he was asked by the tower if he wanted to land runway 15 which he accepted, turned onto final, stabilized his approach and was slowing the aircraft for landing. He stated that his approach speed was approximately 90 knots. The pilot reported his left wing dropped and he was unable to control the aircraft. He stated that the control wheel was operable but the ailerons were ineffective. The pilot reported there were no cockpit indications of a stall. The aircraft departed the runway heading 90 degrees to the left and struck a tree top approximately 30 feet above AGL, continued to roll and the right wing contacted the ground 50 feet from the initial impact point leaving a 17 foot ground scar. The propeller separated from the engine when it impacted the ground and was located 40 feet from the ground scar. A ground scar from engine impact was approximately 8 feet from the propeller. The engine separated from the aircraft and continued forward along the impact path and coming to rest 6 feet forward of the fuselage both approximately 138 feet from the initial point of impact.
