| 01-31557 | Airworthiness Directives; Pratt & Whitney (PW) PW2000 Series Turbofan Engines | Proposed Rule | This action revises an earlier proposed airworthiness directive (AD), applicable to certain Pratt & Whitney (PW) PW2000 series turbofan engines, that would supersede an existing airworthiness directive (AD) by modifying the airworthiness limitations section of the manufacturer's manual and an air carrier's approved continuous airworthiness maintenance program to incorporate additional inspection requirements. This action revises the proposed rule by adding the low pressure compressor (LPC) hub assembly, high pressure turbine (HPT) 1st stage disk, and HPT 2nd stage hub to the additional inspection requirements. The regulatory section revises the manufacturer's Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness (ICA), and for air carrier operations revises the approved continuous airworthiness maintenance program. 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. | 2001-12-27 | 2001 | 12 | https://www.federalregister.gov/documents/2001/12/27/01-31557/airworthiness-directives-pratt-and-whitney-pw-pw2000-series-turbofan-engines | https://www.govinfo.gov/content/pkg/FR-2001-12-27/pdf/01-31557.pdf | Transportation Department; Federal Aviation Administration | 492,159 | This action revises an earlier proposed airworthiness directive (AD), applicable to certain Pratt & Whitney (PW) PW2000 series turbofan engines, that would supersede an existing airworthiness directive (AD) by modifying the airworthiness limitations... |
