It is good engineering practice for you to review the machinery history of an engine before an borescope inspection for all EXCEPT which of the following reasons?

Correct Answer: Option D — A torque multiplier.

A torque multiplier is a mechanical tool used to increase output torque, not a component of the gas turbine engine itself. Reviewing machinery history focuses on operational data, previous maintenance, and known issues to guide the borescope inspection, whereas a torque multiplier is irrelevant to the engine's historical performance.
