Airworthiness Directives; Bell Textron Inc. Helicopters and Various Restricted Category Helicopters

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Inc. Model 204B, 205A, and 205A-1 helicopters and various restricted category helicopters. This AD was prompted by a report of cracked main rotor blades (MRBs). This AD requires repetitive inspections of each MRB and removing any cracked MRB from service. 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 helicopters with main rotor blade (MRB) P/N 204-011-250-001, -005, -009, -113, or -117 installed. Serial ranges given apply to Bell 204B (S/N 2001-2070, 2196-2199) and 205A/205A-1 (S/N 30001-30332); restricted-category variants (HH-1K, TH-1F, TH-1L, UH-1 series) are military-surplus derivatives held by various current type certificate holders, and Southwest Florida Aviation International's SW205A-1 helicopters are included.

Whether AD 2022-21-11 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 2022-21-11 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.
