Is AD 2013-02-01 a recurring Airworthiness Directive?

No — AD 2013-02-01 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2013-02-01 apply to?

AD 2013-02-01 applies to Bell — models 206L, 206L-1, 206L-3, 206L-4. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

We are adopting a new airworthiness directive (AD) for Bell Model 206L, 206L-1, 206L-3, and 206L-4 helicopters. This AD requires inspecting certain hydraulic servo actuator assemblies (servo) for a loose nut, shaft, and clevis assembly, modifying or replacing the servo as necessary, and reidentifying the servo. This AD is prompted by an investigation after an accident and the determination that there was a loose connection due to improper lock washer installation. These actions are intended to detect loose or misaligned parts of the servo to prevent failure of the servo and subsequent loss of control of the helicopter.

Models206L, 206L-1, 206L-3, 206L-4

Serial-conditional — narrows to serials 52001–52430.

Part-conditional — 206-076-062-103.

Applies only when hydraulic servo actuator assembly (servo) P/N 206-076-062-103 is installed. Model 206L, 206L-1, and 206L-3: all serial numbers. Model 206L-4: S/N 52001 through 52430 only.

Whether AD 2013-02-01 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 2013-02-01 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.
