C. Leak Test
(b) Examine the air duct (13) for signs of air leakage.
(2) If necessary, repair the leak.
5. Close-upWARNING:
PUT ON PROTECTIVE GOGGLES AND THERMAL GLOVES WHEN YOU GO NEAR AN AIR-CONDITIONING PACK WHEN IT OPERATES. THERE CAN BE LEAKAGE OF HOT AIR, WHICH CAN CAUSE INJURIES.
(1) Do the two subsequent steps at the same time. NOTE: Two persons are necessary to do these steps.
(a) Do the operational test of the conditioned service air system with bleed air (Ref. AMM TASK 21-58-00-710-002). (b) Examine the air duct (13) for signs of air leakage.
(2) If necessary, repair the leak.
