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.

Gear collapsed on touch down. (.4) during final landing approach the airplane touched down hard resulting in substantial damage. The pilot was demonstrating a power off landing. During the landing flare, he noticed that his 'aiming point' was 'moving in the wrong direction.' He 'immediately tried to add power and as [he] was doing this [he] arrived at the ground - 3 pointed the aircraft, which resulted in damage.' The pilot stated that the runway had 'a large drop from about 50 percent of the length to the north.' He further stated that he thought 'the gradual loss of headwind when [he] descended below the crest of the runway, and the resultant loss of translational lift, allowed an increase in descent rate that went undetected until the flare.' (-23) pilot stated that while demonstrating a power off landing, the descent rate increased. The pilot failed to arrest the descent resulting in a hard landing. The aircraft received substantial damage to the firewall, landing gear, propeller and left wing.

As the FAA filed it

GEAR COLLAPSED ON TOUCH DOWN. (.4) DURING FINAL LANDING APPROACH THE AIRPLANE TOUCHED DOWN HARD RESULTING IN SUBSTANTIAL DAMAGE. THE PILOT WAS DEMONSTRATING A POWER OFF LANDING. DURING THE LANDING FLARE, HE NOTICED THAT HIS 'AIMING POINT' WAS 'MOVING IN THE WRONG DIRECTION.' HE 'IMMEDIATELY TRIED TO ADD POWER AND AS [HE] WAS DOING THIS [HE] ARRIVED AT THE GROUND - 3 POINTED THE AIRCRAFT, WHICH RESULTED IN DAMAGE.' THE PILOT STATED THAT THE RUNWAY HAD 'A LARGE DROP FROM ABOUT 50 PERCENT OF THE LENGTH TO THE NORTH.' HE FURTHER STATED THAT HE THOUGHT 'THE GRADUAL LOSS OF HEADWIND WHEN [HE] DESCENDED BELOW THE CREST OF THE RUNWAY, AND THE RESULTANT LOSS OF TRANSLATIONAL LIFT, ALLOWED AN INCREASE IN DESCENT RATE THAT WENT UNDETECTED UNTIL THE FLARE.' (-23) PILOT STATED THAT WHILE DEMONSTRATING A POWER OFF LANDING, THE DESCENT RATE INCREASED. THE PILOT FAILED TO ARREST THE DESCENT RESULTING IN A HARD LANDING. THE AIRCRAFT RECEIVED SUBSTANTIAL DAMAGE TO THE FIREWALL, LANDING GEAR, PROPELLER AND LEFT WING.
