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.
During an experimental test flight to test a new non-certified powerplant and propeller, the aircraft had a sudden and uncommanded nose down pitch approximately 200 feet above ground level during the approach phase of the landing that resulted in a hard landing causing the left main landing gear a-frame to break off and allowing the propeller to contact the ground.
