Is AD 2019-05-01 a recurring Airworthiness Directive?

Yes — AD 2019-05-01 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Airworthiness Directive 2019-05-01

Q: Which aircraft does AD 2019-05-01 apply to?

AD 2019-05-01 applies to Pratt & Whitney — models PW2037, PW2037D, PW2037M, PW2040, PW2040D, PW2043, PW2143, PW2643. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

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.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Whether AD 2019-05-01 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:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD 2019-05-01 complied with on your aircraft?

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.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
