AD 2011-4465 · 2011-03-10 · airframe

Airworthiness Directives; Bell Helicopter Textron Canada Limited (BHTC) Model 206A, 206B, 206L, 206L-1, 206L-3, 206L-4, 222, 222B, 222U, 230, 407, 427, and 430 Helicopters

What this AD requires

This document publishes in the Federal Register an amendment adopting Emergency Airworthiness Directive (AD) 2010-26-51, which was sent previously to all known U.S. owners and operators of the specified model helicopters by individual letters. This AD also supersedes existing AD 2009-08-03. This AD is prompted by another incident in which the tail rotor blade (blade) tip weight separated from a blade during flight causing vibration. This unsafe condition led to the determination that additional blades could be affected and should be added to the applicability. The actions specified by this AD are intended to prevent loss of the blade tip weight, loss of a blade, and subsequent loss of control of the helicopter.

Certificated in any category.

Whether AD 2011-4465 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 2011-4465 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.
