B. Reverse Thrust Control System Test
(1)
Equipment and Materials
(a)
Spring scale - 0- to 30-pound capacity
(b)
Airplane Control Surfaces Protractor - 4MIT65B80307-1 or F52485-500
(c)
Protractor Adapter, Thrust Lever - F72952-15 (Preferred), F72952-2 (Optional)
(d)
Protractor Assembly, Reverse Thrust Lever - F70044-500 (preferred) or F70044
(e)
A BMS 3-11 hydraulic test bench capable of delivering 20 gpm at 3000 psi with pressure adjustment from 0 to 3000 psi and filters capable of filtering to 5 microns absolute. Airplane B hydraulic system can be pressurized i n lieu of hydraulic test bench (Ref 29-11-0, Hydraulic System A).
(2)
Prepare reverse thrust control system for test.
(a) Pressurize thrust reverser hydraulic system as follows: 1) Provide electrical power. 2) Check that ground lock assemblies F80109-3 are removed from both thrust
reverser isolation valves. 3) Place landing gear selector lever in DN position. 4) Place both forward thrust levers in IDLE position. 5) Place both reverse thrust levers in OFF position.
WARNING: ASSURE THAT REVERSE THRUST LEVER IS IN OFF POSITION AND HYDRAULIC SYSTEM IS NOT PRESSURIZED TO PREVENT PERSONNEL INJURY FROM REVERSER DEFLECTOR DOOR OPERATION.
6) Check that engine fire switches are closed.
7) Place engine thrust reverser override switch to NORMAL.
8) Pressurize hydraulic systems A and B using the B system electric motor-driven
pumps or by connecting ground hydraulic test bench to ground service connection forward of right wheel well. Increase pressure to 3000 psi (Ref 29-11-0, Hydraulic System A).
9) Close ENG 1 THRUST REVERSER and ENG 2 THRUST REVERSER circuit breakers on P6 panel.
10) Close MASTER CAUTION circuit breakers, DIM & TEST circuit breakers, and nine INDICATOR circuit breakers on P6 panel.

11) Place engine No. 1 and 2 thrust reverser override switches on P5 panel to OVERRIDE position.
WARNING: PERSONNEL SHALL STAND CLEAR OF THRUST REVERSERS. SERIOUS INJURIES COULD RESULT FROM BEING CAUGHT BY ROTATING DEFLECTOR DOORS. REVERSE THRUST LEVERS SHALL NOT BE OPERATED WHILE PERSONNEL ARE WORKING ON THRUST REVERSERS AND OVERRIDE SWITCHES ARE IN OVERRIDE POSITION.
(3) Test reverse thrust control system.
(a)
Test engine reverse thrust control system friction.
(b)
Move reverse thrust lever aft toward full reverse thrust from the OFF position and check the following lever loads as measured at 90 degrees to a line through the knob centerline and the lever pivot: 1) With forward thrust lever against idle stop, load required to pull reverse thrust
lever out of OFF detent shall be 1.0 +2.5/-0 pounds.

2) Reverse thrust lever load shall not exceed 9.5 pounds after the detent roller is pulled out of the OFF detent and prior to entering the No. 1 detent (Fig. 510).
3) Reverse thrust lever load shall be 7.0 +5.0/-0 pounds when moving the lever out of the No. 1 detent toward maximum power (No. 2) detent.
4) Prior to entering the maximum power (No. 2) detent the reverse thrust lever load shall then decrease to the load (9.5-pound maximum) observed before entering the No. 1 detent.
5) It shall require a load of ll.0 +8.0/-0 pounds to move the reverse thrust lever through the No. 2 detent towards maximum reverse thrust.
