| Description |
There was an accident to a single engine aircraft.
From the eye and ear witness accounts, it was
established that the accident occurred because of engine
failure. After preliminary examination of the wreckage of
the crashed engine, a few suspected components were
identified for detailed laboratory investigation. The objective
was to establish the primary failure in the engine. While
majority of the engine components submitted for laboratory
analysis showed secondary damages due to either crash
impact forces or post-accident fire, the fracture pattern in
one of the compressor disks was different from other
components of the engine. Fractographic study revealed
that the failure of the disk was by fatigue mechanism.
Subsequent investigation showed that the fatigue fracture of
the compressor disk was the first in the chain of events that led to the engine failure. This finding was further substantiated through fracture mechanics calculations.
