Pratt & Whitney - Model PWC34910-400 - Borescope Guide Tube
Whenever undertaking fuel nozzle maintenance, make sure to perform a borescope inspection at the same time. To do this, you will need a borescope, including a borescope guide tube for accessing hard-to-reach areas of the engine. Using an articulating borescope is much easier than the old-fashioned method, which involves opening up the engine. To prevent videoscope or borescope damage, often times a cool down period is required after the shut down of engines, boilers and furnaces in order to reduce the internal temperature below 170 degrees F (76.7C).
