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.

A flight instructor and a student were practicing touch and go landings on runway 31R at Hillsboro airport. They flight instructor stated he had made 2 landings previously and on their third landing they conducted a go around. As the student added power the engine began to run rough and began to backfire. The student closed the carb heat and had full throttle and mixture rich and the airplane was still running rough and backfiring. The instructor tried to reduce the throttle to idle and then add power again but the engine continued to run rough, especially at high power settings. The CFI stated the RPM was lower than usual, the engine did not seem to develop full power and the aircraft was losing altitude. The CFI elected to land straight ahead off the end of the runway. They landed on the main wheels and initially the aircraft was on its main gear but as it slowed down the nose dug into the ground and the airplane flipped over upside down. The pilots evacuated the airplane and sustained no injuries.
