Airworthiness Directive · Amendment 39-11284 · Dowty Aerospace Propellers Model R381/ 6-123-F/5 Propellers
Dowty Aerospace Propellers Model R381/ 6-123-F/5 Propellers
Dowty Aerospace Propellers Model R381/6-123-F/5 propellers, installed on but not limited to SAAB 2000 series airplanes.
This amendment adopts a new airworthiness directive (AD) that is applicable to Dowty Aerospace Propellers Model R381/6-123-F/5 propellers. This action requires initial and repetitive visual and ultrasonic (UT) inspections of propeller blades for cracks across the camber face, and, if blades are found cracked, replacement with serviceable blades. This amendment is prompted by reports of a cracked composite propeller blade. The actions specified in this AD are intended to prevent propeller blade cracks and propagation, which could result in propeller blade separation and possible aircraft loss of control.
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.
