Dowty Aerospace Propellers Type R334/4-82-F/13 Propeller Assemblies
Superseded. A later AD replaced this one: AD 2004-13-01. Comply with the one in force.
This airworthiness directive (AD) is applicable to Dowty Aerospace Propellers, Type R334/4-82-F/13, with propeller hub assemblies, part number (P/N) 660709201. These propeller hub assemblies are installed on, but not limited to, Construcciones Aeronauticas, S.A. (CASA) 212 airplanes.
This amendment adopts a new airworthiness directive (AD) that is applicable to Dowty Aerospace Propellers Type R334/4-82-F/13 with propeller hub assemblies, part number (P/N) 660709201. This action requires a one-time ultrasonic inspection of the propeller hub for cracks. This amendment is prompted by a report of an in-flight loss of a propeller. The actions specified in this AD are intended to prevent propeller hub failure due to cracks in the hub, which could result in loss of control of the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
