Procedure for identifying noises using the borescope

Procedure for identifying noises using the borescope

The borescope shows the interior of various components and can be used to search for additional indications leading to the cause of a noise at hidden locations and without the need to remove components.

Examples:

Check vent flaps, fans and push rods on bulkheads.

Check bearings for metal particles and proper condition.
