Investigation number:
Status: Active
Investigation in progress


The ATSB has commenced a transport safety investigation into an uncommanded engine power reduction involving the Beechcraft King Air 200C, VH-VAH, at Essendon Airport, Vic., 19 August 2021.

At about 50 ft on take-off, a partial power loss from the number one engine resulted in a momentary loss of directional control and a failure to achieve climb performance. The pilot restored climb power and continued the take-off. The pilot later reported the number one engine throttle friction was not set correctly. The investigation is continuing.

The evidence collection phase of the investigation will include interviewing the crew, a review and examination of operational manuals, maintenance records and the gathering of any other relevant evidence. 

 A report will be published at the conclusion of the investigation. Should a critical safety issue be identified during the course of the investigation, the ATSB will immediately notify relevant parties, so that appropriate safety action can be taken.
