SIL Summary
This SIL introduces an AMM Temporary Revision governing autopilot servo installation.
SIL Background
EAI recently identified a condition in which an improperly installed autopilot servo bridle cable could become displaced during servo installation, resulting in restricted movement of the related flight control(s).
Eclipse Action
The servo installations are similar for the pitch, roll, and yaw axes. EAI has issued AMM Temporary Revision No. TR22-2 to emphasize the exact procedures maintainers must follow to ensure proper servo and flight control operation. This TR will be incorporated into a future revision of the AMM.
Suggested Operator Action
Maintainers should review AMM TR22-2 and ensure the servo bridle cable anchor ball is securely locked into the servo capstan ball detent when installing an autopilot servo.
