25 7. Finish Procedures CAUTION: INSTRUCTIONS AND PROCEDURES IN THIS SECTION INVOLVE PROPELLER CRITICAL PARTS. REFER TO THE INTRODUCTION CHAPTER OF THIS MANUAL FOR INFORMATION ABOUT PROPELLER CRITICAL PARTS. NOTE: A. Paint Specific Hartzell Propeller Inc. manuals and service documents are available on the Hartzell website at Refer to the Required Publications section in the Introduction chapter of this manual for the identification of these publications. (1) Propeller blades are painted with a durable specialized coating that is resistant to abrasion. If this coating becomes eroded, it is necessary to repaint the blades to provide proper corrosion and erosion protection. (2) Polane finish coating is a more durable coating than the aerosol finish coating. However, the aerosol finish coating is a quicker process and is an acceptable option for field repairs given time and location constraints. (a) Regardless of the finish option, wash primer Mix Number 3 is needed for good paint adhesion to the erosion shield. 1 Wash primer Mix Number 3 is required for use with the Polane finish option when refinishing any portion of the erosion shield. 2 Wash primer Mix Number 3 is not required for use with the aerosol finish option. 3 When applying wash primer Mixture Number 3, do so in accordance with the section, "Mixtures" in the Tooling and Materials chapter in this manual. (b) If the Polane finish coat is preferred, contact one of the following: 1 An authorized propeller repair facility to complete the finish procedure. 2 Hartzell Propeller Inc. Product Support for the applicable procedure information from Hartzell Propeller Inc. Standard Practices Manual 202A ( ) (c) If the aerosol finish coat is preferred, refinish the repaired area(s) in accordance with the Painting of Composite Blades section of the Maintenace Practices chapter in the applicable Hartzell Propeller Inc. propeller owner's manual.

26 B. Erosion Tape (1) Installation of Erosion Tape CM158, is required for N7605(C)( ), N( )7893( ), N( )8301( )-( ), N( )8302( )-( ), 75A01-2( ), L76A01X( ), N76M05C( )X, and H79A06X( ) non-booted blades. CAUTION 1: CAUTION 2: EROSION TAPE CM158 MUST BE INSTALLED ON ALL N7605(C)( ), N( )7893( ), N( )8301( )-( ), N( )8302( )-( ), 75A01-2( ), L76A01X( ), N76M05C( )X, AND H79A06X( ) NON- BOOTED BLADES. FAILURE TO INSTALL THE EROSION TAPE ON THESE PROPELLER MODELS CAN RESULT IN SERIOUS DAMAGE TO THE BLADE. DO NOT INSTALL EROSION TAPE CM158 ON A BLADE WITH AN ANTI-ICE BOOT. INSTALLATION OF EROSION TAPE CM158 WILL PREVENT PROPER FUNCTION OF THE ANTI-ICING BOOT. NOTE: The erosion tape CM158 may be installed on the blade before propeller assembly, after propeller assembly, or on-wing. (a) A minimum temperature of 60 F (10 C) is required for erosion tape CM158 application. (b) Keep hands clean at all times. CAUTION: DO NOT INSTALL EROSION TAPE CM158 ON A BLADE THAT HAS PAINT THAT HAS CURED LESS THAN 8 HOURS. (c) If performed in conjunction with paint refinish or touch-up, paint must cure for a minimum of 8 hours before installing erosion tape CM158. (d) Cut erosion tape CM158 to the correct length for each blade. Refer to Table 4-2.
