(3) Avoid the use of blade paddles. If blade paddles must
be used, use at least two paddles. Do not put the blade
paddle in the area of the de-ice or anti-icing boot when
applying torque to a blade assembly. Put the blade
paddle in the thickest area of the blade, just outside of
the de-ice or anti-icing boot. Use one blade paddle per
blade.
(4) Use only the approved consumables, e.g., cleaning
agents, lubricants, etc.
(5) Observe applicable torque values during maintenance.
(6) Before installing the propeller on the engine, the
propeller must be statically balanced. New propellers are
statically balanced at Hartzell Propeller Inc. Overhauled
propellers must be statically balanced by a certified
propeller repair station with the appropriate rating before
return to service.
(a) Dynamic balance is recommended, but may be
accomplished at the discretion of the operator,
unless specifically required by the airframe or engine
manufacturer.
1 Perform dynamic balancing in accordance
with the Maintenance Practices chapter of this
manual.
2 Additional procedures may be found in the
aircraft maintenance manual.
(7) As necessary, use a soft, non-graphite pencil or crayon
to make identifying marks on components.
(8) As applicable, follow military standard NASM33540
for safety wire, safety cable, and cotter pin general
practices. Use 0.032 inch (0.81 mm) diameter stainless
steel safety wire unless otherwise indicated.
(9) The information in this manual revision supersedes data
in all previously published revisions of this manual.
(10) The airframe manufacturer's manuals should be used in
addition to the information in this manual due to possible
special requirements for specific aircraft applications.
