Task Instructions
1. Jack the aircraft using the built-in jack points. (796 Empty Weight and CG Measurement While on Jackpoint Scales)
2. Disconnect the landing gear actuator from the bell crank.
3. With the end of the actuator free, continue to watch the excessive friction occurring within the actuator installation after powering up the aircraft and actuating the landing gear.
4. Retract and extend the disconnected landing gear installation by hand. Verify no binding of gear leg under its own weight.
5. Reconnect the landing gear actuator, lower aircraft, and remove jacks.
Verification Method
Retracting and extending the landing gear verifies there is excessive friction within the system. Contact ICON for further instructions.
