What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Learjet, Inc., Model 35, 35A (C-21A), 36, 36A, 55, 55B, 55C, and 60 airplanes. This AD was prompted by a report indicating that a repair station approved Learjet spoiler assemblies for return to service after extending their life limit. This AD requires removing certain spoiler assemblies from service and prohibits their installation. The FAA is issuing this AD to address the unsafe condition on these products.

Models35, 35A, 36, 36A, 55, 55B, 55C, 60

Applies only to airplanes with any spoiler assembly meeting either: (1) the spoiler assembly's life limit was extended by Restored Aircraft Sales and Service, LLC, or (2) the maintenance records related to the life limit for the spoiler assembly are missing or incomplete. Model 35A is also known by military designation C-21A.

Whether AD 2022-05-01 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 2022-05-01 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.
