Pratt & Whitney Turbofan Engines AD

AD 2010-21-17

The FAA is adopting a new airworthiness directive (AD) for Pratt & Whitney
(PW) JT8D-9, -9A, -11, -15, -17, and -17R turbofan engines. This AD requires
overhauling fan blade leading edges at the first shop visit after 4,000
cycles-in-service (CIS) since the last total fan blade overhaul was
performed. This AD results from reports of failed fan blades. We are issuing
this AD to prevent high-cycle fatigue cracking at the blade root, which
could result in uncontained failures of first stage fan blades and damage to
the airplane.

DATES: This AD becomes effective November 12, 2010.
