 A. Thrust Reverser Deactivation.
 WARNING : MAKE SURE THAT THE THRUST REVERSER IS LOCKED. IF NOT, THE
_______ THRUST REVERSER CAN OPERATE ACCIDENTALLY AND CAUSE INJURY TO PERSONNEL AND/OR DAMAGE TO THE REVERSER.
 (1) Do a check of the primary lock, as follows:

 (a) Make sure the blocker doors are closed and flush with the thrust reverser structure.

 (b) Pull the blocker door with your hand to make sure the door cannot open.

 (2) Make the Thrust Reverser Unserviceable.
 (Ref. Fig. 401/TASK 78-30-00-991-300)

 (a) Remove the quick-release pin from the operational position on the HCU (see sheet.1).
