Brake cooling times after a high speed RTO should be calculated conservatively

18 Jul 2022
On 15 August 2019, a Boeing 767-300 made a high speed rejected takeoff because of increasing noise from an unsecured flight deck sliding window. Whilst subsequently taxiing during the calculated brake cooling time, fire broke out in the left main gear bay and the aircraft was stopped and an emergency evacuation was carried out whilst the fire was being successfully extinguished. The Investigation did not identify any specific cause for the brake unit fires but noted that the reject had been called when 3 knots above V1 and that the maximum speed subsequently reached had been 14 knots above it.
