Airworthiness Directive 2006-16-01
one-timeAirworthiness Directives; Hamilton Sundstrand Model 14RF-19 Propellers
What this AD requires
The FAA is superseding an existing airworthiness directive (AD) for Hamilton Sundstrand model 14RF-19 propellers. That AD currently requires replacing certain actuator yokes with improved actuator yokes. This AD requires the same actions. This AD results from the discovery of a part number (P/N) error in the applicability paragraph of AD 2006-12-19. 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.
Which aircraft AD 2006-16-01 applies to
Applies to propellers with actuator yoke arm part number 810436-2, which might be installed in actuator assemblies part number 790199-6 (correction of a part-number error in AD 2006-12-19). Installed on, but not limited to, SAAB 340 airplanes.
Whether AD 2006-16-01 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:
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.
