Airworthiness Directives; Bell Helicopter Textron, Inc. Model 47B, 47B-3, 47D, 47D-1, 47G, 47G-2, 47G-2A, 47G-2A-1, 47G-3, 47G-3B, 47G-3B-1, 47G-3B-2, 47G-3B-2A, 47G-4, 47G-4A, 47G-5, 47G-5A, 47H-1, 47J, 47J-2, 47J-2A, and 47K Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to Bell Helicopter Textron, Inc. (BHTI) Model 47B, 47B-3, 47D, 47D-1, 47G, 47G-2, 47G-2A, 47G-2A-1, 47G-3, 47G-3B, 47G-3B-1, 47G- 3B-2, 47G-3B-2A, 47G-4, 47G-4A, 47G-5, 47G-5A, 47H-1, 47J, 47J-2, 47J- 2A, and 47K helicopters, that requires installing a safety washer kit designed to preclude separation of the stabilizer bar damper link (damper link) if the damper link rod end bushing (bushing) loosens and exits the damper link rod end. This amendment is prompted by two reported incidents in which the bushings loosened and exited the damper link rod ends, allowing the damper link to slide over the retention bolt and separate from the stabilizer bar (in the first incident), and from the hydraulic damper (in the second incident). The actions specified by this AD are intended to prevent failure of the damper link assembly, which can result in degraded control response and subsequent loss of control of the helicopter.

Part-conditionalCA-047-96-022-1.

Model 47 inferred from Bell Alert Service Bulletin number 47-96-22 (Bell embeds model number in its SB numbering); requires removing stabilizer bar damper link assemblies, installing safety washer kit P/N CA-047-96-022-1, and reinstalling, per Bell ASB 47-96-22 dated Aug 16, 1996. Compliance within 100 hours TIS or 120 calendar days.

Whether AD 98-07-09 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 complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 98-07-09 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.
