Hartzell Propeller, Inc. Compact Series Propellers
Superseded. A later AD replaced this one: AD 2007-26-09. Comply with the one in force.
This airworthiness directive (AD) is applicable to Hartzell Propellers, Inc. Models ( )HC-( )( )Y( )-( )( )( ) compact series constant speed or feathering propellers with Hartzell manufactured "Y" shank blades. These propellers are used on but not limited to the following airplanes: Aermacchi S.pA. (formerly Siai-Marchetti) S-208 Aero Commander 200B and 200D Aerostar 600 Beech 24, 35, 36, 45, 55, 56TC, 58, 60, and 95 Bellanca 14 and 17 series Cessna 182 and 188 Embraer EMB-200A Maule M5 Mooney M20 and M22 Pilatus Britten Norman, or Britten Norman BN-2, BN-2A, and BN-2A-6 Piper PA-23, PA-24, PA-28, PA-30, PA-31, PA-32, PA-34, PA-36, and PA-39 Pitts S-1T and S-2A Rockwell 112, 114, 200, 500, and 685 series
This amendment supersedes an existing airworthiness directive (AD), that is applicable to Hartzell models ( )HC-( )( )Y( )-( )( )( ) compact series, constant speed or feathering propellers with Hartzell manufactured "Y" shank blades. That AD currently requires initial and repetitive blade inspections; rework of all "Y" shank blades including cold rolling of the blade shank retention radius; blade replacement and modification of pitch change mechanisms for certain propeller models; and changing the airplane operating limitations with specific models of propellers installed. This amendment requires initial blade inspections, with no repetitive inspections; rework of all "Y" shank blades including cold rolling of the blade shank retention radius, blade replacement and modification of pitch change mechanisms for certain propeller models; and changing the airplane operating limitations with specific models of propellers installed. This amendment is prompted by FAA reviews of propeller service histories since the issuance of AD 77-12-06R2. The actions specified by this AD are intended to prevent failure of the propeller blade from fatigue cracks in the blade shank radius, which can result in damage to the airplane and loss of airplane 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.
