For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/PHZL/44 Amdt 8 and issues the following AD under subregulation 39.001(1) of CASR 1998.  The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.

Propellers - Variable Pitch - Hartzell
AD/PHZL/44 Amdt 9  Propeller Attachment Bolts  7/2005

Applicability:  Hartzell Propeller model HC-B3TN-2, HC-B3TN-3, HC-B3TN-5, HC-B4TN- 3,
                HC-B4TN-5, HC-B4MN-5, and HC-B5MP-3 turbine engine propellers.
Requirement:       1. Install all new propellers and serviceable propellers, as follows:

                     a. Install the propeller oil seal to the engine flange after ensuring that the engine and propeller flanges are clean.

                     b. Carefully install propeller on the engine flange ensuring that complete and true contact is established.

                     c. Apply MIL-T-83483 Petrolated Graphite, or Hartzell Lubricant part number (P/N) A-3338, to threads of the eight P/N B-3339 attaching bolts (and remainder of bolt if desired) and to flat surfaces of the eight P/N A-2048-2 washers, or to other equivalent approved serviceable bolts and washers.

                     d. Install the eight P/N B-3339 attaching bolts and eight P/N A-2048-2 washers, or other equivalent approved serviceable bolts and washers, that were prepared in paragraph 1.c. of this AD, through the engine flange and into the propeller flange.

                     e. Torque all attaching bolts with a torque wrench and an appropriate adapter, to 40 ft.-lbs., and then to 80 ft.-lbs., following sequence "A" (shown below).  Final torque all attaching bolts using sequence "B" (shown below) to 100
                     ft.-lbs. to 105 ft.- lbs. Safety wire all attaching bolts in an approved manner.

                  f. Once the propeller is installed with P/N B-3339 bolts and P/ N A-2048-2 washers or other equivalent approved serviceable bolts and washers, this AD no longer applies.

                2. For propellers in the applicability list, that are currently installed with P/N
                A-2047 attaching bolts:

                  a. check the torque, with a torque wrench and an appropriate adapter, of all eight propeller attaching bolts (with washers installed).  Torque should be 100 ft-lbs. to 125 ft.-lbs., with dry threads.  Do not use any lubricant with the P/N A-2047 bolts.  Safety wire all bolts in an approved manner.

             Note 1:  A P/N A-2047 bolt has the letter "H" stamped inside a triangle on the bolt. A P/N B-3339 bolt has the P/N stamped inside the cupped head.

                  b. During torque check per Requirement 2
