Traditionally helicopter gearbox failure analysis has been achieved in a number of ways, including the recording of the oil temperature and oil pressure of critical components within the transmission system. Vibration monitoring techniques provide a sufficient level of detail such that all drive train components can be monitored throughout flight. Each indicator relates to specific faults, such as shaft misalignment, gear tooth cracking, bearing inner-race damage, and lubrication problems.
