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.

Instructor and student were in level flight at approximately 2500 feet and about to begin practicing stalls when they heard a loud bang. Oil spattered the windshield. The instructor pilot executed an emergency landing on the beach below the training area. There was no additional damage to the aircraft after landing. Investigation showed two holes in the engine case. Further investigation revealed a broken connecting rod bolt which caused the piston rod to penetrate the engine crank case and engine failure.
