Reims Cessna FR172K, G-PJTM
Whilst on approach to Filton, a loud ‘thud’ was both heard and felt by the pilot. Damage was subsequently found to be present on the propeller blades, the cowling and on the cooling fins of the two front right cylinders on the engine. There was no direct evidence to indicate that the aircraft had struck an airborne object, or that any part of the aircraft had become detached to cause the observed damage. A witness mark on one propeller blade suggested that the object may have been a tool which migrated forward from the engine compartment to be struck by the propeller.
