Airworthiness Directives; Bell Helicopter Textron Canada Model 430 Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 430 helicopters that requires modifying the electrical system. This amendment is prompted by the loss of electrical power due to design deficiencies discovered during single-pilot Instrument Flight Rules (IFR) flight testing. The actions specified by this AD are intended to prevent loss of electrical power and subsequent loss of control of the helicopter.

Which aircraft AD 2001-05-09 applies to

MakesBell

Cross-reference boilerplate only; model list precedes excerpt and was not captured. Requires modifying the electrical system per Bell Helicopter Textron Alert Service Bulletin No. 430-99-10, dated December 16, 1999, to prevent loss of electrical power; Transport Canada AD CF-2000-08 referenced.

Whether AD 2001-05-09 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 2001-05-09 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.
