Boeing 757-2K2, G-LSAN
Approximately three hours of a post-maintenance airtest had elapsed when the flight crew identified a lateral fuel imbalance, which they determined as being caused by a fuel leak from the right engine. The flight crew carried out the ‘Engine Fuel Leak’ QRH checklist which resulted in the right engine being shut down, following which the crew made a single-engine diversion and landing at Newcastle Airport, without further incident. The cause of the fuel leak was identified as a damaged O-ring seal in a part of the right engine’s fuel system that had been recently replaced due to embodiment of a recommended Service Bulletin. The engine manufacturer and maintenance organisation involved are both implementing safety actions intended to prevent a recurrence.
