This action revises an earlier proposed airworthiness directive (AD), applicable to certain Pratt & Whitney JT9D series turbofan engines, that would supersede an existing airworthiness directive (AD) by adding additional critical life-limited parts for enhanced inspection. That proposal was prompted by an FAA study of in- service events involving uncontained failures of critical rotating engine parts. This action revises the proposed rule by adding rear compressor drive turbine shafts to the parts to be included in the revision to the manufacturer's Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness (ICA), and the approved continuous airworthiness maintenance program for air carrier operations. The actions specified by this proposed AD are intended to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane.

Supplemental notice of proposed rulemaking; reopening of comment period.
