AAIB investigation to Airbus A320-232, 9H-LOZ
Engine loss of control and in-flight shutdown, Stansted Airport, Essex, 28 May 2021.
Summary:
On a routine short flight, during final approach to land, the No 2 engine reduced to idle and would not respond to any control inputs. The flight crew performed a missed approach and, following the relevant checklist procedure, elected to shut down the engine. They then performed an uneventful single-engine approach and landed safely. The engineering investigation determined that the cause of the engine problem was most likely an inadvertent activation of the overspeed protection valve in the fuel control system. The problem has occurred previously on other V2500 engines and is being addressed through safety actions by the engine and aircraft manufacturers.
