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) Student pilot on first solo cross country. During cruise flight he dropped an object in the cockpit and, while recovering it, he unknowingly engaged the 2 axis autopilot. He experienced what he thought to be a runaway elevator trim. He did not recognize that the autopilot was operating. After gaining control of the aircraft he contacted the hnl afss for an assist to the nearest airport which was lny. He overrode the autopilot for the 12 miles to the airport and made an uneventful landing. He contacted the flight school. A technician and the student's instructor were dispatched to lny. It was determined that the autopilot was engaged. After disengaging the autopilot the aircraft was flown to hnl by the student and his instructor with no further problems. Since this incident Cessna AD 2003-24-13 has been published. This AD corrects a problem in this particular a/p that caused inadvertent and undetected engagement. The incident was caused by a combination of an a/p malfunction and the experience level of the pilot.
