(d) Subject

(d) Subject

    Joint Aircraft System Component (JASC) Code 7314, Engine Fuel 
Pump.

(e) Unsafe Condition

(e) Unsafe Condition

    This AD was prompted by the manufacturer's investigation into an 
unexpected reduction in fuel pump performance in certain high life 
fuel pumps. Further troubleshooting of the fuel pump discovered 
life-related wear-out of the internal components, which causes 
deterioration in fuel pump efficiency. The FAA is issuing this AD to 
reduce the risk of reduced thrust during engine operation. The 
unsafe condition, if not addressed, could result in failure of the 
fuel pump, loss of thrust control, and loss of the airplane.

    (1) Before exceeding 16,000 hours in service or 4,900 engines
