4. Procedure
_________ (Ref. Fig. 601/TASK 72-42-00-991-301) Subtask 72-42-00-010-063
A. Remove parts before borescope inspection.
(1) Remove the drain tube from the fuel nozzle adjacent to the 6 o'clock borescope plug.
NOTE : If you remove the drain tube from the fuel nozzle adjacent to
____ the 6 o'clock borescope plug, you will be required to perform a leak check after this inspection. Use the 6 o'clock borescope port only if necessary.
(2) Remove the borescope plugs from the approximate 1, 3, 6 and 10 o'clock positions.
(3) Remove both spark igniters (Ref. TASK 74-21-30-000-002).

B. Do a borescope inspection.
(Ref. Fig. 607/TASK 72-42-00-991-307, 608/TASK 72-42-00-991-308)
NOTE : Use the MONITOR, RESOLUTION BORESCOPE (856A1323G01) to make sure
____ borescope and the lightsource are serviceable. See the Non-Destructive Test Manual for this procedure (Ref. NTM 720000).
(1) Connect the fiber light cable to the BORESCOPE KIT (856A1320 P04 ot P05) and to the port on BORESCOPE - LIGHT SOURCE SET (856A1322 P03 or P04 or P07).
(2) Put the rigid borescope, (856A1320 P04 or P05), into the left side ignitor position and turn on the light source of borescope-lightsource set.
(3) Turn the borescope until you can see the deflector plate, sleeve, primary swirler, and the fuel nozzle tip that is located clockwise from the ignitor. 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320飞机维护手册 AMM ENGINE 发动机 2(47)
