What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Asap accepted.
Suspected auto-pilot failure when intercepting the localizer for landing, (all controls became stiff and the aircraft went into a nose down attitude losing altitude and difficult to control the aircraft). Tower requested altitude check and provided vectors for a second landing attempt. The pilot recovered the aircraft and landed on the second attempt.
The certificate holder had an appropriately rated repair station test and evaluate the autopilot system. No discrepancies were noted, however the GMC-605 autopilot controller was replaced as a precautionary measure.
The certificate holder concluded the internal tap-root investigation interview with the pilot and the evaluation of the auto-pilot parameters, manufactures testing report, obtained from the repair station.
The certificate holder was unable to conclusively determine the causal factors of the event to attribute pilot error or system failure.
The GMC-605 auto-pilot controller has been replaced and no further auto-pilot discrepancies have been noted. No regulatory violation can be noted. The maintenance corrective actions taken by the certificate holder and mitigation of future occurrences have been satisfactorily met.
