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 pilot stated "in the landing configuration I entered a wing low approach with right aileron and left rudder. I was in perfect alignment with the runway and the wind was steady. As we entered ground effect everything

Felt solid. I kept a little power in for a wheel landing and the right, main gear wheel touched gently down. As the tail stayed up the left, main gear wheel settled to the grass runway. I reduced throttle and felt the tail wheel start to settle and I brought the stick back to pin the tail wheel down. As the tail wheel settled, the wind started pushing the tail hard to the left causing me to nose right. I attempted to correct with differential left braking as the airplane continued to lose speed on the ground. The nose continued to come around to the right until we were

Perpendicular in the runway but still within the runway threshold limits. As we slowed we skidded sideways down the runway and were nearly at a stop when the airplane tilted left causing the left wing to drop and strike the ground on the left side of the runway. I kept the stick back and the nose stayed up preventing a prop strike. As the left wing hit the ground, evidently

The left elevator also struck the ground as the airplane pitched left. We came to a stop and the

Airplane settled on both main wheels sideways on the runway.

As the FAA filed it

THE PILOT STATED "IN THE LANDING CONFIGURATION I ENTERED A WING LOW APPROACH WITH RIGHT AILERON AND LEFT RUDDER. I WAS IN PERFECT ALIGNMENT WITH THE RUNWAY AND THE WIND WAS STEADY. AS WE ENTERED GROUND EFFECT EVERYTHING

FELT SOLID. I KEPT A LITTLE POWER IN FOR A WHEEL LANDING AND THE RIGHT, MAIN GEAR WHEEL TOUCHED GENTLY DOWN. AS THE TAIL STAYED UP THE LEFT, MAIN GEAR WHEEL SETTLED TO THE GRASS RUNWAY. I REDUCED THROTTLE AND FELT THE TAIL WHEEL START TO SETTLE AND I BROUGHT THE STICK BACK TO PIN THE TAIL WHEEL DOWN. AS THE TAIL WHEEL SETTLED, THE WIND STARTED PUSHING THE TAIL HARD TO THE LEFT CAUSING ME TO NOSE RIGHT. I ATTEMPTED TO CORRECT WITH DIFFERENTIAL LEFT BRAKING AS THE AIRPLANE CONTINUED TO LOSE SPEED ON THE GROUND. THE NOSE CONTINUED TO COME AROUND TO THE RIGHT UNTIL WE WERE

PERPENDICULAR IN THE RUNWAY BUT STILL WITHIN THE RUNWAY THRESHOLD LIMITS. AS WE SLOWED WE SKIDDED SIDEWAYS DOWN THE RUNWAY AND WERE NEARLY AT A STOP WHEN THE AIRPLANE TILTED LEFT CAUSING THE LEFT WING TO DROP AND STRIKE THE GROUND ON THE LEFT SIDE OF THE RUNWAY. I KEPT THE STICK BACK AND THE NOSE STAYED UP PREVENTING A PROP STRIKE. AS THE LEFT WING HIT THE GROUND, EVIDENTLY

THE LEFT ELEVATOR ALSO STRUCK THE GROUND AS THE AIRPLANE PITCHED LEFT. WE CAME TO A STOP AND THE

AIRPLANE SETTLED ON BOTH MAIN WHEELS SIDEWAYS ON THE RUNWAY.
