Narrative:
The aircraft was departing from Heathrow for Boston when, during the take-off roll, a following
aircraft reported that a panel had fallen from G-CIVI. Take off was continued but during the initial
climb the cabin crew reported damage to the trailing edge flap in the region of No 4 engine. The
Commander consulted with his company maintenance control who advised him (having
identified the panel) to return with No 4 engine at idle and not to use reverse thrust. Fifteen tonnes of fuel was jettisoned and the aircraft landed back at Heathrow without further incident.

Upon inspection it was found that No 4 engine had lost one of its two combustion side fairings (see
diagram) whilst the other was found still partially attached but badly distorted in the Integrated
Nozzle Assembly (INA) which had suffered impact damage from the departing panel, as had the
exhaust corona. The other side fairing was recovered from the runway. The right outboard aft
trailing edge flap had lost a roughly triangular section of honeycomb structure, some 30 centimeter
x 12 centimeter, and the entire trailing edge closing fillet, about 6 meters x 2 centimeter, had been
knocked off. Both the damage to the engine and the flap necessitated their replacement before
further flight.
