AAIB investigation to P84 Jet Provost Mk 5. G-VIVM
Runway overrun following rejected takeoff, North Weald Airport, 16 June 2021.
Summary:
The commander performed a rejected takeoff (RTO) due to a reported lack of indication on the air speed indicator (ASI). Despite braking, the aircraft did not come to a stop before the end of the runway. It departed the paved surface into a grassy area and came to rest after striking a shallow earth bank and the airport perimeter fence. There were no injuries.
Examination and testing did not identify any defects with the aircraft’s airspeed indicator or pitot/static system. Examination of the wheels and brakes did not identify any defects but accident damage prevented testing of the braking system. Damage to the wheels and brakes was consistent with the application of heavy braking during a high energy RTO.
The investigation considered that the braking demand arising from the rejected takeoff exceeded the ability of the aircraft braking system to bring the aircraft to a stop, in the available distance remaining.
