Airworthiness Directives; Bell Helicopter Textron Canada Limited Model 206A Series, 206B Series, 206L Series, 407, and 427 Helicopters

What this AD requires

This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2009-07-52 and supersedes Emergency AD 2009-07-51, issued March 17, 2009, which was sent previously to all known U.S. owners and operators of Bell Helicopter Textron Canada Limited (Bell) Model 206A series, 206B series, 206L series, 407, and 427 helicopters by individual letters. This AD requires, before further flight, inspecting each cyclic control lever assembly (lever assembly) that has less than 50 hours time-in-service (TIS) to determine if it is correctly installed and properly staked in the lever assembly. This amendment is prompted by a Transport Canada AD report of a bearing incorrectly installed in the copilot lever assembly. The actions specified by this AD are intended to prevent failure of a bearing, failure of the lever assembly, and subsequent loss of control of the helicopter.

Whether AD E9-8573 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 E9-8573 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.
