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 accident ocurred at the end of a 2.9 hour flight that started and ended at Nampa Municipal Airport (man). The flight began with an aerotow to 4,000 MSL (1500 AGL) and covered an area between Nampa, Idaho and ontario, Oregon. Soaring flight altitudes varied from release to around 8,000 MSL.the decent to landing commenced from 8,500 MSL at a position 4.5 miles southwest of Nampa (man). The downwind was entered at 3,800 MSL at 55 KTS., turned base leg at 3,000 MSL at 50 KTS. And final at 2,800 MSL at 50 KTS.on final the flaps were set 40 degrees. As the approach continued the pilot felt he was going to land further down the runway than desired so more flap was added. The sink rate suddenly increased and then available energy was depleted causing the aircraft to land short of the runway. The hard landing off runway caused the landing gear to collapse then resulting in the right wing contacting the ground. The aircraft then yawed severely finally making contact with the runway and sliding approxamatly another 50 feet. Upon exiting the aircraft the pilot realized the flaps had been extended to the 90 degree position. This was 30 degrees more than intended.

As the FAA filed it

THE ACCIDENT OCURRED AT THE END OF A 2.9 HOUR FLIGHT THAT STARTED AND ENDED AT NAMPA MUNICIPAL AIRPORT (MAN). THE FLIGHT BEGAN WITH AN AEROTOW TO 4,000 MSL (1500 AGL) AND COVERED AN AREA BETWEEN NAMPA, IDAHO AND ONTARIO, OREGON. SOARING FLIGHT ALTITUDES VARIED FROM RELEASE TO AROUND 8,000 MSL.THE DECENT TO LANDING COMMENCED FROM 8,500 MSL AT A POSITION 4.5 MILES SOUTHWEST OF NAMPA (MAN). THE DOWNWIND WAS ENTERED AT 3,800 MSL AT 55 KTS., TURNED BASE LEG AT 3,000 MSL AT 50 KTS. AND FINAL AT 2,800 MSL AT 50 KTS.ON FINAL THE FLAPS WERE SET 40 DEGREES. AS THE APPROACH CONTINUED THE PILOT FELT HE WAS GOING TO LAND FURTHER DOWN THE RUNWAY THAN DESIRED SO MORE FLAP WAS ADDED. THE SINK RATE SUDDENLY INCREASED AND THEN AVAILABLE ENERGY WAS DEPLETED CAUSING THE AIRCRAFT TO LAND SHORT OF THE RUNWAY. THE HARD LANDING OFF RUNWAY CAUSED THE LANDING GEAR TO COLLAPSE THEN RESULTING IN THE RIGHT WING CONTACTING THE GROUND. THE AIRCRAFT THEN YAWED SEVERELY FINALLY MAKING CONTACT WITH THE RUNWAY AND SLIDING APPROXAMATLY ANOTHER 50 FEET. UPON EXITING THE AIRCRAFT THE PILOT REALIZED THE FLAPS HAD BEEN EXTENDED TO THE 90 DEGREE POSITION. THIS WAS 30 DEGREES MORE THAN INTENDED.
