| 2020-27511 | Airworthiness Directives; Pratt & Whitney Turbofan Engines | Proposed Rule | The FAA proposes to supersede Airworthiness Directive (AD) 2012-04-15, which applies to all Pratt & Whitney (PW) JT9D-3A, JT9D-7, JT9D-7A, JT9D-7AH, JT9D-7F, JT9D-7H, JT9D-7J, JT9D-20, JT9D-20J, JT9D- 59A, JT9D-70A, JT9D-7Q, JT9D-7Q3, JT9D-7R4D, JT9D-7R4D1, JT9D-7R4E, JT9D-7R4E1, JT9D-7R4E4, JT9D-7R4G2, and JT9D-7R4H1 (JT9D) model turbofan engines. AD 2012-04-15 requires revisions to the Airworthiness Limitations Section (ALS) of the manufacturer's Instructions for Continued Airworthiness (ICA) to include required enhanced inspection of selected critical life-limited parts at each piece-part opportunity. AD 2012-04-15 also requires additional revisions to the JT9D model engines ALS of the manufacturer's ICA. Since the FAA issued AD 2012-04- 15, PW notified the FAA that revisions to the mandatory inspections contained within the ALS of the manufacturer's ICA were necessary. This proposed AD would revise the required inspections of selected critical life-limited parts specified in the ALS of the manufacturer's ICA and, for air carriers, to the existing continuous airworthiness air carrier maintenance program (CAMP). The FAA is proposing this AD to address the unsafe condition on these products. | 2020-12-15 | 2020 | 12 | https://www.federalregister.gov/documents/2020/12/15/2020-27511/airworthiness-directives-pratt-and-whitney-turbofan-engines | https://www.govinfo.gov/content/pkg/FR-2020-12-15/pdf/2020-27511.pdf | Transportation Department; Federal Aviation Administration | 492,159 | The FAA proposes to supersede Airworthiness Directive (AD) 2012-04-15, which applies to all Pratt & Whitney (PW) JT9D-3A, JT9D-7, JT9D-7A, JT9D-7AH, JT9D-7F, JT9D-7H, JT9D-7J, JT9D-20, JT9D-20J, JT9D- 59A, JT9D-70A, JT9D-7Q, JT9D-7Q3, JT9D-7R4D,... |
