| 2016-30114 | Airworthiness Directives; Pratt & Whitney Turbofan Engines | Proposed Rule | We propose to supersede Airworthiness Directive (AD) 2014-05- 32, which applies to all Pratt & Whitney (PW) PW2037, PW2037D, PW2037M, PW2040, PW2040D, PW2043, PW2143, PW2643, and F117-PW-100 turbofan engines. AD 2014-05-32 currently requires one-time eddy current inspection (ECI) of affected engines with certain diffuser and HPT cases installed. AD 2014-05-32 also requires a fluorescent-penetrant inspection (FPI) of the diffuser case rear flange and the HPT case front flange. Since we issued AD 2014-05-32, the manufacturer determined through analysis that the inspections required by AD 2014- 05-32 are not adequate to maintain safety. This proposed AD would add additional repetitive, on-wing ECI inspections. We are proposing this AD to correct the unsafe condition on these products. | 2016-12-22 | 2016 | 12 | https://www.federalregister.gov/documents/2016/12/22/2016-30114/airworthiness-directives-pratt-and-whitney-turbofan-engines | https://www.govinfo.gov/content/pkg/FR-2016-12-22/pdf/2016-30114.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We propose to supersede Airworthiness Directive (AD) 2014-05- 32, which applies to all Pratt & Whitney (PW) PW2037, PW2037D, PW2037M, PW2040, PW2040D, PW2043, PW2143, PW2643, and F117-PW-100 turbofan engines.
