On 23 August 2019 at approximately 1620 Western Standard Time, the crew of a Fokker 100 was commencing take-off from Perth Airport, Western Australia for a regular public transport flight. The captain was pilot monitoring and the first officer was pilot flying.
During the take-off run, the first officer’s seat suddenly moved back. As the seat slid back, the first officer released the control column so as not to pull it back with him, and was unable to reach the pedals once the seat had stopped at the aft limit.
The aircraft then veered slightly to the right of the runway centreline and the first officer declared, ‘Handing over’. The captain immediately took over control of the aircraft and conducted a rejected take-off.
The operator suspected that the locking mechanism on the seat had failed.
This incident highlights the importance of a rapid and decisive handover/takeover procedure undertaken by the crew, which was demonstrated in this occurrence.
The US Federal Aviation Administration publication, Aviation Instructor’s Handbook, includes further information and guidance on the positive exchange of flight controls.
