Trim runaway was a possible scenario identified by the Air Accidents Investigation Branch in a report into a 2017 Piper PA-31 fatal accident.
The pilot reported pitch control problems and diverted to Caernarfon Airport where the aircraft crashed on an attempted landing. The elevator trim was found in a significantly nose-down position.
You can read the full AAIB report in the
