Functional Test of the Rudder Bar
WARNING:
MAKE SURE THAT THE CONTROLS AGREE WITH THE POSITION OF THE ITEMS THEY OPERATE BEFORE YOU PRESSURIZE A HYDRAULIC SYSTEM. UNWANTED MOVEMENT OF HYDRAULICALLY OPERATED ITEMS CAN CAUSE SERIOUS INJURY AND/OR DAMAGE.
WARNING:
MAKE SURE THAT THE GROUND SAFETY-LOCKS ARE IN POSITION ON THE LANDING GEAR. THIS WILL PREVENT UNWANTED MOVEMENT OF THE LANDING GEAR, AND THUS POSSIBLE INJURY TO PERSONS AND DAMAGE TO THE AIRCRAFT AND/OR EQUIPMENT.
WARNING:
MAKE SURE THAT THE TRAVEL RANGES OF THE FLIGHT CONTROLS SURFACES ARE CLEAR. MOVEMENT OF FLIGHT CONTROLS CAN CAUSE INJURY TO PERSONS AND/OR DAMAGE TO EQUIPMENT.
WARNING:
BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.

(3) If the test is to be done with the nose wheels on the ground, do these steps:
(b) Apply a thick layer of Synthetic Ester base Grease-General Purpose Low Temp - (Material No.03HBD9) or Synthetic Oil base Grease-General Purpose Clay Thickened - (Material No.03GBB1) to the upper surface of the steel plate.
(d) Move the aircraft and position the nosewheels on the greased steel plates (Ref. AMM TASK 09-10-00-584-002).
(4) If the test is to be done with the nose wheels clear of the ground do this:
(a) Lift the nose gear (Ref. AMM TASK 07-12-00-582-001).
