Date: Friday 1 August 2008
Aircraft Type: Airbus A321-231
Owner/operator: British Midland Airways – BMA
Registration Number: G-MIDL
Location: CRZ FL350 LIS FIR –
ÿ Portugal
Phase of Flight: En route
Casualties: Fatalities: 0 / Occupants: 199
Component Affected: The #2 engine’s HPC (High Performance Compressor).The #2 engine’s HPC (High Performance Compressor).
Investigating Agency: GPIAAGPIAA
Category: Accident
Precautory landing occurred following an engine problem on G-MIDL. Investigation revealed that a deterioration of the #2 engine’s HPC (High Performance Compressor) due to rotor airfoils and stator vanes impact damage caused an HPC loss of efficiency, leading to a stall.Precautory landing occurred following an engine problem on G-MIDL.

Description
Precautionary landing following engine problems. Causes: The investigation concluded that the incident on G-MIDL had its cause in the #2 engine HPC deterioration due to HPC stage 6 rotor airfoils and stator vanes impact damage originated by hard FOD ingestion. These circumstances caused an HPC loss of efficiency with increasing distress resulting in a stall.
