Unsafe Condition
The cumulative effect of individual part tolerances may result in the tail rotor yoke striking another part other than the flapping stop (parts interference). Additionally, the misalignment of the tail rotor counterweight bellcrank may result in higher tail rotor pedal forces and a higher pilot workload after failure of the No. 1 hydraulic system.

Required Actions
Adjust the rigging of the tail rotor pitch change mechanism. If a gap exists between the tail rotor yoke and the flapping stop, replace the tail rotor yoke with an airworthy one. If no gap exists, measure the gap between the tail rotor yoke and nut, P/N 222-012-731-001, and adjust the tail rotor pitch change mechanism and pedal forces.
