Abstract: In aviation non-destructive techniques are used to prevent the failure of aircraft components, to find the cause of failure, how the failure has occurred and steps to be taken to prevent the failure of such components. Aircraft wheels take the impact during landings and assist in taxiing, take off etc. Fatigue cracks and pitting corrosion on the mating surface of aircraft wheel hub is found using eddy current inspection method and cracks on bolts (occurring on thread and shaft region) are found using either magnetic particle inspection or fluid penetrant inspection. The crack was found on the mating region the aircraft wheel hub.
