1 SERVICING GENERAL 1. Introduction This chapter contains details of routine fluid and gaseous replenishment procedures applicable to the whole aircraft, general lubrication, and of commonly used procedures such as application of hydraulic power, external electrical power and external air supply. The location of aircraft servicing points is shown in Figure 1. A list of consumable materials used for servicing the aircraft is shown in Figure 2. For access panel and door locations, refer to Chapter Application of External Hydraulic Power Equipment and Material Power units, hydraulic GSE Ref. No NOTE: The hydraulic power unit must be suitable for use with phosphate ester base fluid. For fluid specification, refer to HYDRAULIC SYSTEM REPLENISHING. A. Connect Ground Hydraulic Power (1) Apply external ac power (refer to paragraph 4.B.). (2) Observe hydraulic fluid safety and technical precautions (refer to Chapter 29). (3) Ensure that controls are set as follows: (a) Flap selector ZERO to prevent actuation of landing/takeoff configuration warning. (b) Landing gear DOWN (c) Manual landing gear IN release (d) Brakes OFF (e) Spoiler selector ZERO (f) Nose wheel steering CENTRAL (g) All flight controls NEUTRAL Page 1 Oct 22/89

2 (4) Check reservoir fluid level and accumulator pressure (refer to HYDRAULIC SYSTEM REPLENISHING). NOTE: Ensure that the reservoir fluid level is replenished. (5) Gain access to hydraulic system servicing panel. NOTE: No. 1 and No. 2 system ground servicing panels are located in the rear fuselage equipment bay, and No 3 panel in the rear fairing of the right wing root (refer to Figure 1). CAUTION: TO PREVENT CONTAMINATION, QUICK DISCONNECT COUPLINGS MUST BE THOROUGHLY CLEANED BEFORE CONNECTION OF GROUND HYDRAULIC POWER. (6) Remove dust covers from quick disconnect couplings on ground servicing panel, clean couplings and secure pressure and suction lines of hydraulic power unit to appropriate connections. B. Remove Ground Hydraulic Power (1) Shutdown the ground hydraulic power unit. WARNING: ENSURE THAT THE LOCK PIN IS INSTALLED IN THE NOSE GEAR DOOR ACTUATOR MECHANISM BEFORE ANY WORK IS DONE IN THE NOSE GEAR WHEEL WELL. MAKE SURE ALL HYDRAULIC PRESSURE IS RELEASED. INJURY TO PERSON AND DAMAGE TO EQUIPMENT CAN OCCUR. CAUTION: DO NOT USE THE AILERONS TO DEPLETE THE HYDRAULIC SYSTEM PRESSURE. WHEN USING THE ELEVATORS DO NOT EXCEED TEN COMPLETE CYCLES. BEFORE RELEASING PRESSURE FROM HYDRAULIC SYSTEMS, ENSURE THAT CHOCKS ARE PLACED AT MAIN WHEELS AND THAT LANDING GEAR GROUND LOCKING PINS ARE INSTALLED (REFER TO CHAPTER 10). (2) Release the system pressure by operating the rudder or the elevator until the pressure gauges on the HYDRAULIC SYSTEMS panel in the flight compartment read zero. To release the brake system pressure, operate the brake pedal until the brake pressure gauge on the pilot s instrument panel reads zero. (3) Disconnect ground hydraulic power unit pressure and suction lines from aircraft hydraulic ground servicing panel. (4) Ensure that quick disconnect couplings are sealing correctly. (5) Check condition of seal in dust covers; replace if necessary. (6) Install dust covers. Page 2 Jun 27/97

3 (7) Close and secure ground servicing panel access door. (8) Check aircraft reservoir fluid level and replenish as necessary (refer to HYDRAULIC SYSTEM REPLENISHING). (9) Remove external ac power (refer to paragraph 4.C.). 3. Application of Aircraft Hydraulic Power A. Pressurize Hydraulic System (1) Apply external ac power to aircraft (refer to paragraph 4.B.). (2) System configuration must be as follows: (a) (b) (c) (d) (e) WARNING: System accumulator charged with nitrogen to prescribed pressure (refer to HYDRAULIC SYSTEM REPLENISHING). Landing gear down and locked. Brakes off. Flight controls neutral. Spoilers closed. MAKE SURE THAT ALL PERSONS AND EQUIPMENT ARE NOT NEAR THE NOSE LANDING GEAR DOORS WHEN YOU PRESSURIZE THE HYDRAULIC SYSTEMS. THE CLOSING OF THE NOSE LANDING GEAR DOORS IS VERY FAST AND CAN CAUSE DEATH OR INJURIES TO PERSONS, AND DAMAGE TO EQUIPMENT. MAKE SURE ALL PERSONS STAND CLEAR OF ANY HYDRAULIC SYSTEM COMPONENTS WHEN THE HYDRAULIC SYSTEM IS PRESSURIZED. A LEAKING COMPONENT CAN SPRAY YOU WITH HOT HYDRAULIC FLUID. INJURIES TO PERSONS AND DAMAGE TO EQUIPMENT CAN OCCUR. (3) Pressurize No. 1 or No. 2 system by setting No. 1 or No. 2 ELECT PUMP switch on HYDRAULIC SYSTEMS panel to ON. Pressurize No. 3 system by setting ELECT PUMP A or ELECT PUMP B switch to ON. (4) Check that applicable electric motor driven pump low pressure warning lights go out and that system pressure stabilizes at 3000 psi. Page 3 Jun 27/97

4 B. Release System Pressure WARNING: ENSURE THAT THE LOCK PIN IS INSTALLED IN THE NOSE GEAR DOOR ACTUATOR MECHANISM BEFORE ANY WORK IS DONE IN THE NOSE GEAR WHEEL WELL. MAKE SURE ALL HYDRAULIC PRESSURE IS RELEASED. INJURIES TO PERSONS AND DAMAGE TO EQUIPMENT CAN OCCUR. CAUTION: DO NOT USE THE AILERONS TO DEPLETE THE HYDRAULIC SYSTEM PRESSURE. WHEN USING THE ELEVATORS DO NOT EXCEED TEN COMPLETE CYCLES. BEFORE RELEASING PRESSURE FROM HYDRAULIC SYSTEMS, ENSURE THAT CHOCKS ARE PLACED AT MAIN WHEELS AND THAT LANDING GEAR GROUND LOCKING PINS ARE INSTALLED (REFER TO CHAPTER 10). (1) Set all ELECT PUMP switches on HYDRAULIC SYSTEMS panel to OFF. (2) Release the system pressure by operating the rudder or the elevator until the pressure gauges on the HYDRAULIC SYSTEMS panel in the flight compartment read zero. To release the brake system pressure, operate the brake pedal until the brake pressure gauge on the pilot s instrument panel reads zero. 4. Application of External Electrical Power Equipment and Material AC ground power unit, GSE Ref. No (refer to ILLUSTRATED TOOL AND EQUIPMENT MANUAL) DC ground power unit, GSE Ref. No A. General Application of electrical power to the aircraft buses can be accomplished by means of external ac or dc power supply. Two external electrical receptacle connection points are provided. One, located on the right side of the forward fuselage, is used to connect the ac supply. The second, located on the right side of the fuselage aft of the wing trailing edge, is used to connect the dc source (refer to Figure 1). Before connection, observe applicable electrical safety precautions (refer to Chapter 24). Ensure aircraft is grounded before connecting external electrical power. Page 4 Jun 27/97

5 B. Apply External AC Power (1) Connect a power supply or ground power unit to external ac receptacle on forward fuselage. Set to 115 volts at 400 Hz. NOTE: An external 28 volt dc power supply, if required, may be used in conjunction with external ac supply (refer to paragraph 4.D.). (2) Switch on ac power supply and check that indicator light marked AVAIL located on electrical control panel, on overhead panel, comes on. (3) Set BATTERY MASTER and GPWR switches to ON in that sequence. Check that IN USE light segment comes on. (4) Set AC METERING switch, located on centre pedestal, to EXT PWR and check that ac voltmeter reads between 112 and 118 volts and that frequency meter reads between 397 and 403 Hz. C. Remove External AC Power (1) Set GPWR and BATTERY MASTER switches to OFF in that sequence. Check that IN USE light segment goes out and that AVAIL light segment remains on. (2) Switch off ac power supply and remove electrical connector from external power receptacle. Check that indicator light segment marked AVAIL on overhead panel goes out. (3) Placard GPWR and BATTERY MASTER switches. NOTE: Remove placards from GPWR and BATTERY MASTER switches after maintenance practices are completed. (4) Remove external dc power if applicable (refer to paragraph 4.E.). D. Apply External DC Power To apply power to aircraft battery bus and battery direct bus from a ground power source, proceed as follows: (1) Connect 28 volt dc power supply to external receptacle aft of wing trailing edge. (2) Set BATTERY MASTER switch to ON and check that BATTERY light is off. E. Remove External DC power (1) Set BATTERY MASTER switch to OFF. Page 5 Jun 27/97
