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.

During takeoff pilot aborted approx 1900 feet down a 3700 foot runway with a load of chemical. The pilot reported no mechanical problems with aircraft and that it did not feel like it was going to fly. During abort pilot stated he used reverse thrust after braking only would not stop aircraft prior to end of runway. Pilot stated he may have got on reverse to hard and went into a 180 degree ground loop to the left substantially damaging the right wing. The pilot stated he used the first mark of flaps which is marked on the left flap. This is to be verified upon wing repair when marks can be inspected. First mark would be consistent with 10 degrees of flaps which is what AFM suggests be use to take off with a load in hopper. This report will be amended if needed to document.
