Condition monitoring and failure analysis: powerful tools for modern military helicopters
Condition monitoring through vibration measurement provides a route for detecting impending failure. However, it is only truly effective when combined with follow-up validating failure analysis to determine the root cause of the failure. Through detailed analysis of Health and Usage Monitoring Systems (HUMS) data, the Materials and Structures Group (M&SG), including the former AD AIM have successfully detected and diagnosed a damaged bearing within the engine transmission of an operational Chinook aircraft. Subsequent metallurgical analysis of the bearing, also performed by M&SG, revealed that a roller within the bearing was presenting a subsurface fault due to fracture that, if left undetected, was likely to have led to catastrophic failure of the transmission, significant secondary damage and airworthiness risk

Abstract
Condition monitoring through vibration measurement provides a route for detecting impending failure. However, it is only truly effective when combined with follow-up validating failure analysis to determine the root cause of the failure. Through detailed analysis of Health and Usage Monitoring Systems (HUMS) data, the Materials and Structures Group (M&SG), including the former AD AIM have successfully detected and diagnosed a damaged bearing within the engine transmission of an operational Chinook aircraft. Subsequent metallurgical analysis of the bearing, also performed by M&SG, revealed that a roller within the bearing was presenting a subsurface fault due to fracture that, if left undetected, was likely to have led to catastrophic failure of the transmission, significant secondary damage and airworthiness risk
