Summary of Problem.
a. The Navy has discovered improperly installed Swage Pin Collars on H-60 Collective and Yaw Boost
Servos. CCAD also found a Yaw Boost Servo with this non-conforming installation with zero time since new.
This improper installation will cause the collars to be loose which may lead to possible loss of the Swage Pin.
This problem is identical to that addressed by TB 1-1520-237-20-205.
b. Manpower/downtime and funding impacts - See paragraph 12.
c. The purpose of this TB is to inspect all Swage Pins and Collars on Collective and Yaw Boost Servo
assemblies for proper installation.
