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.

Narrative: on December 10, 1996, at approximately 3:00 p.m., Mr. Burnham (the pilot) experienced a malfunction of the flight controls. The malfunction occurred while practicing power-on stall recoveries with a student. During the recovery, the student used forward pressure on the flight controls, right aileron, and right rudder. When the ailerons were moved to the neutral position Mr. Burnham realized the flight controls would no longer move to the left, however, he had complete right aileron control. An emergency was declared at this time. Mr. Burnham spent approximately five minutes practicing maneuvering the aircraft. Using left rudder and differential power, Mr. Burnham landed the aircraft safely and without further incident. An inspection revealed that a coaxial cable had become entangled in the control linkage behind the instrument panel. The coaxial was then properly routed and secured by a mechanic, to prevent its further interference. This is a final report.
