A vibration monitored combiner bearing from a RAF Chinook aircraft was removed from service with suspected wear damage. Subsequent analysis discovered that the bearing displayed heavy spalling and was close to complete bearing breakup. If it had not been removed the bearing could have led to catastrophic failure of the aircraft. This represents a significant step forward in Health and Usage Monitoring (HUMS) of UK military helicopters.
