FLIGHT SAFETY PART
Heat treated condition of forward longitudinal and collective bellcranks and bolts, is critical
to their serviceability. Any indication of heat oxidizing (discoloration), where visually detect-
able, requires replacement of the part. These parts must be protected from unscheduled
heating and external impact during inspection and other handling procedures.
Shot-peened surfaces of forward longitudinal bellcrank are critical. This part shall be re-
placed or have the peening restored if surface has had peening removed by wear or other
cause. It also must be protected from unscheduled heating and external impact during
inspection and other handling procedures.
To prevent personal injury or equipment damage, two persons are required for lifting and
removing bellcranks. If injury occurs, seek medical aid.
To prevent damage to bolt, press retention device lock fully when removing bolt.
Do not remove bolts until bellcranks are to be removed from helicopter.
