Is AD 2018-14-10 a recurring Airworthiness Directive?

No — AD 2018-14-10 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2018-14-10 apply to?

AD 2018-14-10 applies to Pratt & Whitney Division — models PW2037, PW2037M, PW2040. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Pratt & Whitney Division Turbofan

What this AD requires

We are superseding Airworthiness Directive (AD) 2017-12-03 for certain Pratt & Whitney Division (PW) PW2037, PW2037M, and PW2040 turbofan engines. AD 2017-12-03 required installing a software standard eligible for installation and precludes the use of electronic engine control (EEC) software standards earlier than SCN 5B/I. This AD requires installing a software standard eligible for installation and preclude the use of EEC software standards earlier than SCN 5B/I or SCN 27A. This AD was prompted by an unrecoverable engine in-flight shutdown (IFSD) after an ice crystal icing event. We are issuing this AD to address the unsafe condition on these products.

Part-conditional — EEC104-40, EEC104-60, EEC104-1, 1B7484, 1B7486, 1B7984, 1B7985.

Applies to (1) engines with EEC model EEC104-40 or EEC104-60 installed, with an EEC software standard earlier than SCN 5B/I; and (2) engines with EEC model EEC104-1 (P/N 1B7484, 1B7486, 1B7984, or 1B7985) installed, with an EEC software standard earlier than SCN 27A.

Whether AD 2018-14-10 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 2018-14-10 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.
