Airworthiness Directives; Bell Helicopter Textron Inc., Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for Bell Helicopter Textron Inc. (Bell) Model 212, Model 412, and Model 412EP helicopters. This AD requires replacing the emergency flotation system (EFS) tube assembly. This AD was prompted by a report of an EFS tube assembly failure. The actions of this AD are intended to address an unsafe condition on these products.

Which aircraft AD 2018-16-14 applies to

MakesBell Helicopter Textron Inc.
Models212, 412, 412EP
Part-conditional — 412-073-820-101.

Applies only to helicopters with an emergency flotation system (EFS) tube assembly P/N 412-073-820-101 manufactured before July 28, 2016, or with an unknown date of manufacture, installed.

Whether AD 2018-16-14 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 2018-16-14 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.
