AD on Pratt and Whitney JT8D Engines
Thursday, March 24th, 2011Airworthiness Directive 2011-07-02 on Pratt & Whitney JT8D-209, JT8D-217, JT8D-217A, JT8D-217C, and JT8D-219 Series Turbofan Engines superseding an existing airworthiness directive (AD) for the products listed above. That AD currently requires initial and repetitive torque inspections of the 3rd stage and 4th stage low-pressure turbine (LPT) blades for shroud notch wear and replacement of the blade if wear limits are exceeded. That AD also requires replacing LPT-to-exhaust case bolts and nuts with bolts and nuts made of Tinidur material. This new AD requires the same torque inspection, blade, and Tinidur nut replacement actions, but requires replacement of the LPT-to-exhaust case bolts with longer bolts made of Tinidur material. This AD also requires installation of crushable sleeve spacers on the bolts.

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.
