Boeing 767-31K, G-TCCB
Whilst airborne, shortly after the rear galley ovens had been switched on, a strong acrid burning smell was noticed emanating from the No 3 oven. The oven was switched off and associated circuit breakers opened. As the acrid smell became more intense a fire extinguisher was discharged into the oven and the aircraft diverted safely.
The oven meal insert tray was damaged and too big for the oven. The oven pin, which prevents the insert tray from touching the exposed elements at the back of the oven, was also found to be bent. This allowed the oven insert to contact the exposed heating elements of the oven.
