NOTE
Commanders will insure that all crew members are made aware of this
special interest inspection and the importance of conducting the inspec-
tion during pre and post flight inspections.
a.
Perform the following inspections.
(1) Initial Inspection. Inspect each bolt, P/N 114R2201--1, apply hand pressure to the head to as-
sure the adhesive is not holding the bolt head in place. If the bolt head is broken off the rotor head is considered
unserviceable until the inspection of paragraph 8b is completed. If it is necessary to remove excessive adhe-
sive RTV, the units have 10 flight hours but no later than 25 May 2000 to comply with proper application of
adhesive RTV in accordance with the note above.
(2) Recurring Inspections. During each daily inspection, preflight and postflight, inspect each
bolt, P/N 114R2201--1. Apply hand presure to the head to assure the adhesive is not holding the bolt head
in place. If the bolt head is broken off, the rotor head is considered unserviceable.
b. If a broken bolt head is found, inspect the following parts while the horizontal hinge pin is disas-
sembled: horizontal hinge pin, tie bar, and nut (reference 13a, figure 176, item 113, 87, and 121 respectively)
or (reference 13b, figure 5--4, item 98, 87, and 121 respectively). Inspect for scoring, deformation or any evi-
dence that parts have abnormal wear.
