Resumen
We are superseding Airworthiness Directive (AD) 2017-11-06, for all Pratt & Whitney (PW) PW2037, PW2037D, PW2037M, PW2040, PW2040D, PW2043, PW2143, PW2643, and F117-PW-100 turbofan engine models. AD 2017-11-06 required initial and repetitive on-wing eddy current inspections (ECIs) of affected engines with certain diffuser and high- pressure turbine (HPT) cases installed. AD 2017-11-06 also required a fluorescent-penetrant inspection (FPI) of the diffuser case rear flange and the HPT case front flange. This AD requires an on-wing ECI of all diffuser case M-flange replacement repairs. This AD was prompted by a rupture of the diffuser-to-HPT case flange. We are issuing this AD to address the unsafe condition on these products.
