Yes — AD 2020-26-13 requires a repetitive inspection every 250 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2020-26-13 apply to?

AD 2020-26-13 applies to Sikorsky Aircraft Corporation — models S-92A, S-92. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Sikorsky Aircraft Corporation Helicopters

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters. This AD was prompted by seven incidents of fatigue cracks in the horizontal stabilizer root fitting FWD (forward root fitting). This AD requires establishing the life limit of certain part-numbered forward root fittings, establishing the life limit of certain part-numbered stabilizer strut fittings, repetitively inspecting certain parts, and depending on the inspection results, removing parts from service. The FAA is issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect every 250 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Whether AD 2020-26-13 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.

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.
