Summary of the Problem.

a. The lower pitch change link bearing, rod end, P/N 70101-08202-101, manufactured by Island Engi-

neering (CAGE code 48137) has recently completed required engineering testing, the results indicate that

the fatigue strength is significantly below that of the original equipment manufactured component and as

such, must be removed from the aircraft. Engineering estimates that 100 hrs of additional service is accept-

able without incurring a significant risk due to this component.

For manpower/downtime and funding impacts, see paragraph 12.

c. The purpose of this TB is to remove all bearing rod end, P/N 70101-08202-101, manufactured by

Island Engineering (CAGE 40137), in accordance with paragraph 9.
