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 climb out from utica, number one channel of the autopilot failed. Number two was engaged and programmed for 160 knot climb. During this climb, the autopilot climbed at a steeper angle and a slower airspeed than what was programmed. And shortly after this, the number two channel failed. We also experienced erratic flight director information. The flight continued for approximately 15 minutes without the use of any autopilot. When a turn to the right was attempted, the controls were jammed. But a turn to the left was possible. It was at this time the crew elected to separate the roll controls. It was discovered that the aileron were jammed. The aircraft was fully controllable with the use of the roll spoilers. It was decided to fly to our maintenance base in VFR conditions. Landing was made at manassas without incidence. Maintenance personnel determined that the roll servo actuator, Honeywell part number 7002260-923 had failed. The component was replaced and the aircraft returned to service. Operator submitted mdr on this event. There are two known similar events in the SDR database.
