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) Right main gear collapsed after touchdown at mmu. Owner stated she had a green light and had a visual gear down on the left side of the aircraft. After touchdown the right main landing gear collapsed, and the aircraft spun around to the left on the runway damaging right wing/right horizontal stabilizer and elevator. (.4) the pilot stated that she received her approach clearance about 12 miles from the airport. At that time, she lowered the landing gear and performed a 'gumps' check which included checking the gas, undercarriage, mixture and propeller. After lowering the landing gear, she observed a green landing gear light. The landing seemed normal, and the pilot did not hear a gear warning horn. The right main landing gear collapsed and the airplane spun 180 degrees on the runway. Examination of the wreckage by a federal aviation administration inspector, and a local mechanic, did not reveal any pre-impact mechanical malfunctions.
