Airworthiness Directives; Bell Textron Inc. Helicopters

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Inc. Model 212, 412, 412CF, and 412EP helicopters. This AD was prompted by a report of a cracked check valve. This AD requires inspecting certain engine oil and fuel check valves, and depending on the results, repetitively inspecting and removing the check valve from service. This AD also prohibits installing affected engine oil and fuel check valves on any helicopter. 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.

MakesBell Textron Inc.
Models212, 412, 412CF, 412EP
Part-conditional — 209-062-520-001, 209-062-607-001.

Applies only if an engine oil check valve P/N 209-062-520-001 or fuel check valve P/N 209-062-607-001, manufactured by Circor Aerospace, is installed, where the valve is marked "Circle Seal" and "CORONA CA" (except not a valve marked "TQL"), and has a manufacturing date code of, or prior to, "9/11" (September 2011), or has no manufacturing date code.

Whether AD 2022-11-19 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 2022-11-19 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.
