WARNING
FLIGHT SAFETY PART
The longitudinal links 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 links is critical to 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 inspec-
tion and handling procedures.
