B. Maintenance Practices
(1) The propeller and its components are highly vulnerable
to damage while they are removed from the engine.
Properly protect all components until they are reinstalled
on the engine.
(2) Never attempt to move the aircraft by pulling on the
propeller.
(3) Avoid the use of blade 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.
