As the aircraft was being decelerated on the wet runway, number 3 engine disintegrated and caught fire. Several wheels and tyres failed and the captain steered the aircraft onto a taxiway where the landing gear collapsed and ultimately the aircraft was destroyed by fire. All on board were airline employees who escaped successfully although two received serious injuries. Due to the loss of No 3 hydraulic system, number 2 brake system, number 3 engine thrust reversers and number 3 spoiler system were all unavailable. Engine imbalance caused the epoxy abradable fan shroud to catch fire due to blade rub. Engine 3 ingested at least one Great black-backed gull and 9 more were found on the runway together with 13 Herring gulls. An Airworthiness Directive required replacement of the fan shroud material.
