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.

(-23) The accident aircraft and crew were engaged in what was the students second instructional flight. After completing an uneventful portion of the flight which incluced upper air work such as straight and leel flight, turns and acceleration/deceleration manuvers the crew returned to Hanscom field (kbed) to conduct some practice of hovering flight prior to concluding the flight. The hovering practice started over the har surface customs ramp but moved to a grass area nea airport taxiways when a medical flight approached the customs ramp for landing. Once the aircraft was established over the grass the instructor had pointed the nose of the aircraft towaards the air traffic control tower (the tower would be used a visual reference to maintain the hover position) and asked the studen to maintain the nose of the aircraft pointed at the tower. Shortly after this the instructor added control of the collective lever to the students control. See continuation sheet.
