Airworthiness Directives; CFM International, S.A. Engines

What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2025-21- 03, which applied to certain CFM International, S.A. (CFM) Model LEAP- 1A23, LEAP-1A24, LEAP-1A24E1, LEAP-1A26, LEAP-1A26CJ, LEAP-1A26E1, LEAP-1A29, LEAP-1A29CJ, LEAP-1A30, LEAP-1A32, LEAP-1A33, LEAP-1A33B2, and LEAP-1A35A engines. AD 2025-21-03 required initial and repetitive borescope inspections (BSIs) of the high-pressure turbine (HPT) rotor stage 1 blades. Depending on the results of the BSIs, AD 2025-21-03 required either additional BSIs at reduced intervals or replacement of the HPT rotor stage 1 blades. Since the FAA issued AD 2025-21-03, the manufacturer published updated service material and determined that engines operating in the South Asia region are susceptible to accelerated HPT rotor stage 1 blade deterioration and airfoil distress. This AD requires initial and repetitive BSIs of the HPT rotor stage 1 blades and, depending on the results of the inspections, additional BSIs at reduced intervals or replacement of the HPT rotor stage 1 blades. The FAA is 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.

Applies only to engines with an installed high-pressure turbine (HPT) rotor stage 1 blade bearing one of the listed part numbers that has accumulated more than 1,100 South Asia takeoffs, and has accumulated 2,500 part cycles since new (PCSN) for Group 1 engines, or 5,100 PCSN for Group 2 engines.

Whether AD 2026-14-06 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 complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 2026-14-06 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.
