Flap gear universal joint trunnion P/N 60903-1655 is limited to a life of 1,500 flights due to the possibility of fatigue cracks developing. Trunnions P/N 60903-1655 exceeding this life should be replaced within the next 50 flights with replacement parts to Mod. D.2188 standard, or removed and inspected for cracks in accordance with PTL 153, issue 3, and if found serviceable may be replaced provided they are inspected at intervals not exceeding 200 flights.
