NOTE
Debond will appear as a paint crack or white line extending spanwise along the spar line. Visually inspect
the bond line area at the tip extending inboard to and including the finger doublers. The bond line is 3.6
INCHES aft of the leading edge. If no paint crack or white line is seen, inspection is complete. If paint
crack or white line is seen, a debond is presumed.

CAUTION
At temperatures at or below 0 F (-17 C), the elastomeric bearings must be warmed up before they can
be checked. Warm up the elastomeric bearings by gently teetering the tail rotor blades back and forth
until the blades can be flexed to their stops. Do not force the blades to their stop during the bearing war-
mup procedure.
