Airworthiness Directives; Hamilton Sundstrand Model 14RF-19 Propellers

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for Hamilton Sundstrand model 14RF-19 propellers. This AD requires replacing certain actuator yokes with improved actuator yokes. This AD results from certain propeller system actuator yoke arms breaking during flight. We are issuing this AD to prevent actuator yoke arms breaking during flight, which could cause high propeller vibration and contribute to reduced controllability of the airplane.

Models14RF-19, 14RF

Part-conditional — 810436-2, 790119-6.

Applies to propellers with actuator yoke arm part number 810436-2, which might be installed in actuator assemblies part number 790119-6. Installed on, but not limited to, SAAB 340 airplanes.

Whether AD 2006-12-19 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 2006-12-19 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.
