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.

Put on full flaps on final. Rolled left and crashed. (.4) the pilot took off in the experimental, homebuilt airplane, for a planned series of approaches to explore the airplane's operating envelope. The first approach was performed without use of the wing flaps, and no anomalies were reported. During the next approach, the pilot fully extended the flaps. The airplane entered a left turn which, according to the pilot, could not be stopped. The pilot lost control of the airplane, it descended and collided with two unoccupied airplanes. The accident occurred during the 7th hour of the flight test program. There were no reported mechanical problems. (-23) pilot reported he was on a test flight of an experimental aircraft. While attempting to land with half flaps, the aircraft became uncontrollable. The pilot stated that upon applying full power, the nose of the aircraft pitched up and yawed left. He then lost control. The aircraft descended to the left, striking two parked aircraft and coming to rest upside down.

As the FAA filed it

PUT ON FULL FLAPS ON FINAL. ROLLED LEFT AND CRASHED. (.4) THE PILOT TOOK OFF IN THE EXPERIMENTAL, HOMEBUILT AIRPLANE, FOR A PLANNED SERIES OF APPROACHES TO EXPLORE THE AIRPLANE'S OPERATING ENVELOPE. THE FIRST APPROACH WAS PERFORMED WITHOUT USE OF THE WING FLAPS, AND NO ANOMALIES WERE REPORTED. DURING THE NEXT APPROACH, THE PILOT FULLY EXTENDED THE FLAPS. THE AIRPLANE ENTERED A LEFT TURN WHICH, ACCORDING TO THE PILOT, COULD NOT BE STOPPED. THE PILOT LOST CONTROL OF THE AIRPLANE, IT DESCENDED AND COLLIDED WITH TWO UNOCCUPIED AIRPLANES. THE ACCIDENT OCCURRED DURING THE 7TH HOUR OF THE FLIGHT TEST PROGRAM. THERE WERE NO REPORTED MECHANICAL PROBLEMS. (-23) PILOT REPORTED HE WAS ON A TEST FLIGHT OF AN EXPERIMENTAL AIRCRAFT. WHILE ATTEMPTING TO LAND WITH HALF FLAPS, THE AIRCRAFT BECAME UNCONTROLLABLE. THE PILOT STATED THAT UPON APPLYING FULL POWER, THE NOSE OF THE AIRCRAFT PITCHED UP AND YAWED LEFT. HE THEN LOST CONTROL. THE AIRCRAFT DESCENDED TO THE LEFT, STRIKING TWO PARKED AIRCRAFT AND COMING TO REST UPSIDE DOWN.
