Is AD 2010-11764 a recurring Airworthiness Directive?

No — AD 2010-11764 is a one-time directive. Verify it was complied with in the aircraft's records.

Airworthiness Directive 2010-11764

Q: Which aircraft does AD 2010-11764 apply to?

AD 2010-11764 applies to Dowty Propellers — models R175/4-30-4/13, R175/4-30-4/13e, R184/4-30-4/50, R193/4-30-4/50, R193/4-30-4/61, R193/4-30-4/64, R193/4-30-4/65, R193/4-30-4/66. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

The FAA is superseding an existing airworthiness directive (AD) for the Dowty Propellers, propeller models listed above. That AD currently requires, for all Dowty Rotol propellers, visual inspections for seizure and for cadmium plating of the blade pitch change operating links and eyebolt fork assemblies. That AD also requires replacement or heat-treatment of the blade pitch change operating links and eyebolt fork assemblies, if necessary. This AD requires the same actions, but only for certain propeller models. This AD results from the FAA determining that AD 70-16-02 does not apply to all propellers, since current Dowty propellers are differently designed. We are issuing this AD supersedure to specify the affected propeller models, and to prevent seizure or embrittlement and cracking of the blade pitch change operating links and eyebolt fork assemblies, which could result in reduced controllability of the airplane.

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.

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.
