WARNING
FLIGHT SAFETY PART
The longitudinal servocylinder mount bracket and/or components of the mount bracket are
flight safety parts. Failure to follow maintenance instructions may result in serious injury or
death of crewmembers and/or serious damage to the helicopter.
Heat-treated condition of the longitudinal servocylinder mount bracket is critical to its
serviceability. Any indication of heat oxidizing (discoloration), where visually detectable,
requires replacement of the part. This part must be protected from unscheduled heating and
external impact during inspection and handling procedures.
Shot-peened surface on mount bracket is critical. This part shall be replaced 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 any other
handling procedures.
