Airworthiness Directive 2014-05-32
one-timeAirworthiness Directives; Pratt & Whitney Turbofan Engines
What this AD requires
We are adopting a new airworthiness directive (AD) for all Pratt & Whitney (PW) PW2037, PW2037D, PW2037M, PW2040, PW2040D, PW2043, PW2146, PW2240, PW2337, PW2643, and F117-PW-100 turbofan engines. This AD was prompted by a rupture of the diffuser-to-high-pressure turbine (HPT) case flange. This AD requires a one-time eddy current inspection (ECI) of affected engines with certain diffuser and HPT cases installed. This AD also requires a fluorescent-penetrant inspection (FPI) of the diffuser case rear flange and HPT case front flange. We are issuing this AD to prevent failure of the diffuser-to-HPT case flange, which could lead to uncontained engine failure and damage to the airplane.
Which aircraft AD 2014-05-32 applies to
Whether AD 2014-05-32 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
