JAL would like to propose the followings. 1. The NPRM states that AMM 28-22-00 and Boeing 777 Task Card 28-020-02-01 are the approved method to comply with the AD. But both AMM 28-22-00 and Boeing 777 Task Card 28-020-02-01 include two tasks. One is "Engine Fuel Suction Feed - Operational Test", and the other is "Engine Fuel - Feed Manifold Air Pressure Leak Check". JAL has been currently performing the operational check of the engine fuel suction feed system in accordance with Maintenance Planning Document, Item Number 28-020-00 for GE90/100 ENG or 28-020-01 for PW4000 ENG. The MPD calls out AMM task TASK 28-22-00-710-802 “Engine Fuel Suction Feed - Operational Test” and AMM task TASK 28-22-15-790-808 “Engine Fuel Feed and Refuel Manifold - Leak Isolation” every 7500 FH interval. Two tasks are equivalent procedures and each one of them would satisfy the operational check requirement of this new AD. Operators would be able to make a selection from the two procedures. JAL requests the FAA to consider clarifying if the operator can choose each one of the two tasks to comply with the new AD.
