Evidences suggest that the damages observed on the stator vanes as well as rotor blades of LP compressor were caused by foreign object and therefore, it can be termed as foreign object damage (FOD). The nature of damages indicates that the foreign object was in the form of soft, solid mass. No traces of foreign object were found present in the damaged regions and hence, the exact nature of the object could not be established. However, evidences do not suggest FOD by hard objects such as metallic materials or pebbles/stones. The rotor blade material was found to conform to the Al-alloy of specification AA2618
