Remove the L (R) thrust reverser half.
(2)
Install the L (R) thrust reverser half.
B.
You must not open, extend or lift the thrust reverser if more than six cascade vane segments are removed. You must install a minimum of three cascade vane segments in each thrust reverser half. The empty space between these three cascade vane segments must be equivalent. There must not be more than two adjacent empty spaces between the three cascade vane segments which are installed.
C.
You can change the left left and right thrust reverser halves between the left and right engines if the cascade vane segments are installed in the specified locations (AMM 78-31-16/401).
D.
When you change the engine, thrust reverser, or strut, it is necessary to adjust the thrust reverser shims (AMM 78-31-01/501).
