Abstract
An on-machine inspection method for detecting whether a shaft of a transmission system has failed uses a test probe from flaw detection apparatus to discover echo signals with known peaks corresponding to defined weakened portions in the shaft. The test probe is then moved to prescribed angular distances about an end face of the shaft to obtain the echo signals.
