The procedure for measuring and inspecting included in the service letter document.
Should the flaperon torque tubes be found to be short, Van's Part Number SL-00022 is a bag that contains the hardware components needed to perform the addition of a special spacer washer on both wings of the aircraft.
This service letter applies only to RV-12iS aircraft (does not apply to the original/legacy RV-12) as defined in the service letter document.
