| 2017-12078 | Airworthiness Directives; Pratt & Whitney Turbofan Engines | Rule | We are superseding Airworthiness Directive (AD) 2014-05-32 for all Pratt & Whitney (PW) PW2037, PW2037D, PW2037M, PW2040, PW2040D, PW2043, PW2143, PW2643, and F117-PW-100 turbofan engines. AD 2014-05-32 required one-time eddy current inspection (ECI) of affected engines with certain diffuser and high-pressure turbine (HPT) cases installed. AD 2014-05-32 also required a fluorescent-penetrant inspection (FPI) of the diffuser case rear flange and the HPT case front flange. This AD requires additional repetitive, on-wing ECI inspections. This AD was prompted by the manufacturer determining through analysis that the inspections required by AD 2014-05-32 are not adequate to maintain safety for certain diffuser cases. We are issuing this AD to correct the unsafe condition on these products. | 2017-06-13 | 2017 | 6 | https://www.federalregister.gov/documents/2017/06/13/2017-12078/airworthiness-directives-pratt-and-whitney-turbofan-engines | https://www.govinfo.gov/content/pkg/FR-2017-06-13/pdf/2017-12078.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We are superseding Airworthiness Directive (AD) 2014-05-32 for all Pratt & Whitney (PW) PW2037, PW2037D, PW2037M, PW2040, PW2040D, PW2043, PW2143, PW2643, and F117-PW-100 turbofan engines.
