Airworthiness Directives; Dowty Propellers Type R321/4-82-F/8, R324/4-82-F/9, R333/4-82-F/12, and R334/4-82-F/13 Propeller Assemblies

Résumé
The FAA is superseding an existing airworthiness directive (AD) for Dowty Propellers Type R321/4-82-F/8, R324/4-82-F/9, R333/4-82- F/12, and R334/4-82-F/13 propeller assemblies. That AD currently requires initial and repetitive ultrasonic inspections of propeller hubs, part number (P/N) 660709201. This AD requires the same initial and repetitive ultrasonic inspections, but makes some needed corrections. This AD results from comments received on AD 2005-20-12. We are issuing this AD to prevent propeller hub failure due to cracks in the hub, which could result in loss of control of the airplane.
