A. Overview
WARNING:
WHEN USING REFLECTIVE TAPE FOR
DYNAMIC BALANCING, DO NOT APPLY
THE TAPE ON EXPOSED BARE METAL OF
A BLADE. THIS WILL ALLOW MOISTURE TO
COLLECT UNDER THE TAPE AND CAUSE
CORROSION THAT CAN PERMANENTLY
DAMAGE THE BLADE. REFLECTIVE TAPE
MUST BE REMOVED AFTER DYNAMIC
BALANCING IS COMPLETED.
NOTE: Dynamic balance is recommended to reduce
vibrations that may be caused by a rotating
system (propeller and engine) imbalance.
Dynamic balancing can help prolong the life of the
propeller, engine, airframe, and avionics.
(1) Dynamic balance is accomplished by using an accurate
means of measuring the amount and location of the
dynamic imbalance.
(2) The number of balance weights installed must not
exceed the limits specified in this chapter.
(3) Follow the dynamic balance equipment manufacturer’s
instructions for dynamic balance in addition to the
specifications of this section.
NOTE: Hartzell

Manual 202A (61-01-02), Chapter 600, also
contains information on weight placement and
balancing.
