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.

The CFI was demonstrating a stabilized approach to landing to the pilotprivacy data omittedof the aircraft during a training flight. The landing was to a hard surfaced runway (2701'X60').the CFI was sole munipulator of the controls during the landing demonstration. The CFI reported calm winds and no turbulance during the approach to the runway. The CFI articulated that the touchdown was normal with no bounce but slightly left of centerline. Soon after touchdown the aircraft began a slight turn to the right as the CFI retracted the flaps. The CFI stated that the right turn continued after completion of the flap retraction and the CFI then made more aggressive control inputs attempting to correct the right turn. The right turn progressed to an approximate 180 degree rotation and the aircraft departed the runway surface toward a parallel taxiway. During the right turn the left wingtip "dipped down" and made contact with the hard surface taxiway. The throttle was at idle power prior to and during the loss of directional control and the aircraft was traveling below take-off speed. The aircraft came to a complete stop in a dirt portion of the airport. The NTSB determined that the damage to the left wing tip and left aileron was substantial.

As the FAA filed it

THE CFI WAS DEMONSTRATING A STABILIZED APPROACH TO LANDING TO THE PILOT^PRIVACY DATA OMITTED^OF THE AIRCRAFT DURING A TRAINING FLIGHT.

THE CFI REPORTED CALM WINDS AND NO TURBULANCE DURING THE APPROACH TO THE RUNWAY. THE CFI ARTICULATED THAT THE TOUCHDOWN WAS NORMAL WITH NO BOUNCE BUT SLIGHTLY LEFT OF CENTERLINE. SOON AFTER TOUCHDOWN THE AIRCRAFT BEGAN A SLIGHT TURN TO THE RIGHT AS THE CFI RETRACTED THE FLAPS.THE CFI STATED THAT THE RIGHT TURN CONTINUED AFTER COMPLETION OF THE FLAP RETRACTION AND THE CFI THEN MADE MORE AGGRESSIVE CONTROL INPUTS ATTEMPTING TO CORRECT THE RIGHT TURN. THE RIGHT TURN PROGRESSED TO AN APPROXIMATE 180 DEGREE ROTATION AND THE AIRCRAFT DEPARTED THE RUNWAY SURFACE TOWARD A PARALLEL TAXIWAY. DURING THE RIGHT TURN THE LEFT WINGTIP "DIPPED DOWN" AND MADE CONTACT WITH THE HARD SURFACE TAXIWAY. THE THROTTLE WAS AT IDLE POWER PRIOR TO AND DURING THE LOSS OF DIRECTIONAL CONTROL AND THE AIRCRAFT WAS TRAVELING BELOW TAKE-OFF SPEED. THE AIRCRAFT CAME TO A COMPLETE STOP IN A DIRT PORTION OF THE AIRPORT. THE NTSB DETERMINED THAT THE DAMAGE TO THE LEFT WING TIP AND LEFT AILERON WAS SUBSTANTIAL.
