AD: Pratt & Whitney (PW) Turbofan Engines

AD NUMBER: 2012-06-14

PRODUCT: PW JT9D-7R4G2 and -7R4H1 turbofan engines.
SUBJECT: Airworthiness Directive 2012-06-14
ACTION: Final Rule

SUMMARY: This AD was prompted by the determination that a new lower life limit for high-pressure turbine (HPT) 1st stage air seals, part number (P/N) 735907, is necessary. This AD establishes a new lower life limit for HPT 1st stage air seals, P/N 735907, and requires removing them from service using a drawdown schedule. The FAA is issuing this AD to prevent critical life-limited rotating engine part failure and damage to the airplane.

DATES: This AD is effective April 27, 2012.
