You should never use force when introducing the borescope guide tube into the aviation engine. The PWC34910-804 borescope guide tube is used to inspect the high-pressure turbine vanes (HPT Vanes) and small exit duct. To satisfactorily complete this engine inspection, you must use a borescope that offers at least 2-way articulation. Most aviation maintenance professionals prefer a borescope with 4-way articulation or a joystick articulating system.
This is a rigid borescope guide tube that requires a borescope diameter of 5mm or less. Most common for this airplane engine borescope inspection is a 4mm diameter borescope.
