This is an excerpt from a report made to the Aviation Safety Reporting System. The narrative is written by the pilot, rather than FAA or NTSB officials. To maintain anonymity, many details, such as aircraft model or airport, are often scrubbed from the reports.
When attempting to disengage the autopilot (AP), the servos refused to release control of the aircraft. The p-trim began raising the nose, while I pushed the nose forward to preclude a stall. Altitude was 9,500 feet.
When the AP would not disengage I pushed the disengage button on the yoke. When that didn’t work, I pulled the circuit breaker to the autopilot. That didn’t work either, the servos refuse to release. I then turned off the G5 flight instruments and the servos released.
After approximately 5 to 10 minutes I turned the G5 flight instruments back on and hand flew the aircraft to its destination.
I am having avionics technicians look at the autopilot and the installation.
I haven’t used the autopilot to much extent until yesterday.
