In September 2018, Flight Global reported on an incident that occurred on a commercial aircraft in which an axle fatigue crack led to a failure of the left nose landing gear axle and separation of the left nose wheel. “The cause of the abusive grinding could not be determined, but the abusive grinding would probably have been identified if a post-grinding Barkhausen inspection had been carried out.”
See the hidden damages with RoboScan. New video now available.
Check out GearScan 500 video. GearScan 500 allows for fast detection of common manufacturing problems such as grinding re-temper burn, heat treatment, and stress related defects.
