Procedure
1
General
This data module gives the maintenance procedure to replace the O ring seal in the LH and RH wing
fuel tank drain valves.
Two different types of drain valve can be installed.
To identify which drain valve type is installed, use the Fuel sample unit (Pt.No. T12-020) to push
and turn the valve clockwise. If the valve mechanism drops to expose the O ring, the valve has a
replaceable O ring. If the valve does not drop, the valve does not have a replaceable O ring.
