SERVICING
**** Hidden Message ***** SERVICING – GENERAL1. General
A. The design of this airplane provides for most of the servicing to be accomplished from the right
side of the fuselage. To avoid interference during ground servicing activities, passenger loading
doors are located forward and aft on the left side of the fuselage.
B. This chapter contains instructions and precautions for replenishment of items involved in
servicing the airplane. Charts are provided to show tank and reservoir capacities. See figures
201 and 202 for general service layout.
C. Diagrams are provided to show location and identification of access panels.
D. Airplane cleaning instructions and periodic lubrication requirements for the airplane are
included.
E. Figures 203 and 204 locate the wing and stabilizer walkway areas approved by Boeing. If
walkway areas are marked on the airplane, they will be marked per BAC drawing 65-45211
1. General
A. This procedure has moved to the subsequent procedures:
(1) Precautions and Limits for Fuel Servicing (AMM 12-11-01/301)
(2) Prepare the Airplane for the Refuel Operation (AMM 12-11-01/301)
(3) Pressure Refueling (AMM 12-11-02/301)
(4) Overwing Refueling (AMM 12-11-03/301)
(5) Alternative Refueling Procedures (AMM 12-11-04/301)
(6) Fuel System Drainage (AMM 12-11-05/301).
B. Fuel Servicing Regulations
(1) Each operator is responsible for complying with the local, state and national regulations
regarding aircraft fuel servicing. It is possible that fire codes and standards make it
necessary to use different or more restrictive procedures than those given in the above
procedures. Make sure the procedures used during the refuel operation give sufficient
protection to persons and equipment.
(2) If you make a decision not to do these recommended procedures, you must have an
approved alternative procedure.

B. Fuel Servicing Regulations
(1) Each operator is responsible for complying with the local, state and national regulations
regarding aircraft fuel servicing. It is possible that fire codes and standards make it
necessary to use different or more restrictive procedures than those given below. Make
sure the procedures used during the refuel operation give sufficient protection to persons
and equipment.
(2) If you make a decision not to do this recommended procedure, you must have an
approved alternative procedure.
(3) Refuel procedures can be found in these procedures:
(a) Pressure Refueling (AMM 12-11-02/301)
(b) Overwing Refueling (AMM 12-11-03/301)
(c) Alternative Refueling Procedures (AMM 12-11-04/301)
(d) Fuel System Drainage (AMM 12-11-05/301).
2. Precautions and Limits for Fuel Servicing
A. General
(1) Obey all of the precautions in this task when you refuel the airplane.
B. Emergency Procedures
(1) Obey all airport and operator provided fire protection, rescue and fuel spill emergency
procedures. Emergency procedures include these subjects:
(a) Location of emergency fuel shutoff
(b) Airport fire department phone numbers
(c) Evacuation of airplane passengers
(d) Fuel spill containment and ignition source reduction
(e) Location and use of fire extinguishers
(f) Responsibilities of fuel servicing and airplane servicing personnel.
(2) Refuel the airplanes in areas which allow the free movement of air, fire fighting equipment
and other emergency equipment.
(3) Stop the refuel operation if any conditions change which could cause an unsafe condition
for persons or equipment.
C. Fuel Spills
(1) Each fuel spill event is different. Variables such as the size of the spill, weather
conditions, equipment location, aircraft occupancy, emergency equipment and personnel
available will determine the correct response to control the fire hazard.
(2) During a refuel operation, continuously monitor the airplane for fuel leaks and spills.
(3) If a fuel spill occurs, do these steps:
(a) Stop the fuel flow.
(b) Unload and shutdown the APU. Do the usual APU shutdown procedure (Refer to
Chapter 49).
(c) Follow the fire department and operator provided fuel spill and fire protection
emergency procedures.
(d) Find and correct the cause of the fuel spill.
(e) Inspect enclosed areas to make sure they are free of fuel vapor.
(f) Do not begin the refuel operation or start the APU again until the fire department or
the person(s) in charge have given approval.
D. Passenger Precautions
(1) Obey all airport and operator procedures if you refuel the airplane with passengers
onboard.
WARNING: OBEY THE SUBSEQUENT PASSENGER PRECAUTIONS DURING A
REFUEL OPERATION. IF YOU DO NOT OBEY THESE REQUIREMENTS,
INJURY TO PERSONS CAN OCCUR.
(2) For each airplane type, a hazardous area must be identified for boarding or unloading
passengers during a refuel operation. Barriers must be in position to stop passengers
from entering this hazardous area.
E. Airplane System Precautions
(1) Do not operate these systems during a refuel operation:
(a) Weather mapping radar
(b) HF communications system
(2) Do not do these maintenance tasks during a refuel operation:
(a) Re-start an APU if that APU experienced an automatic shutdown or a failed start
attempt during its' previous operation unless refueling is suspended.
(b) Connect or disconnect the battery chargers, aircraft ground-power generators or
other electrical ground-power
(c) Fill or change oxygen bottles
(d) Remove electrical power.
NOTE: Damage to the refuel system components can occur.
(e) Begin a refuel operation if a fire or engine overheat condition exists
(f) Begin a refuel operation if any part of the landing gear is unusually hot.
(3) Make sure these components are in the closed position before you begin the refuel
operation:
NOTE: Fuel spills, damage to the airplane or inability to close doors can occur if these
components are not closed.
(a) Wing pressure relief valves (if installed)
(b) Landing gear doors
(c) Overwing entry doors (if installed)
(4) Damage or wear at the fueling receptacle adapter can cause fuel leaks. Do these
maintenance actions to prevent fuel leaks:
(a) Make sure the mating surface of the fuel hose and fueling receptacle adapter are
clean and free from unwanted material.
(b) Make sure the slots and lugs on the adapter are not damaged.
(c) Use a wear gauge to make sure the adapter is within operational limits.
(5) Make sure the landing gear wheel chocks do touch the tires. The wheel chocks can
wedge against the tire after you add fuel.
(6) A refuel operation with a main engine operating is an emergency procedure. Obey all
airport and operator provided emergency procedures.
F. APU Operations During Refueling and Defueling - Limits and Precautions
(1) Obey the limits for APU operation (AMM 49-11-0/201).
WARNING: OBEY THE LIMITS AND PRECAUTIONS FOR APU OPERATION DURING
REFUELING. IF YOU DO NOT OBEY THESE LIMITS AND PRECAUTIONS,
INJURY TO PERSONS AND DAMAGE TO EQUIPMENT CAN OCCUR.
(2) You can start the APU during a refueling operation if the start is an initial start or a restart
after normal shutdown.
(3) You can shutdown the APU (manual or automatic) during a refueling operation.
(4) If there is a protective automatic shutdown or failure to start condition on the APU, stop the
refueling operation and disconnect the fuel hose from the airplane fueling receptacle
adapter before you start the APU again.
(5) If an APU fire occurs, do these steps in this sequence:
(a) Stop the refueling operation.
(b) Make sure the APU shutdowns automatically.
1) If the APU does not shutdown automatically, do the APU Emergency Shutdown
Procedure (AMM 49-11-0/201).
(c) Discharge the APU fire bottles (AMM 49-11-0/201).
(d) Obey all airport and operator supplied fire protection and emergency procedures.
(6) If a fuel spill occurs, do these steps:
(a) Unload and shutdown the APU (AMM 49-11-0/201).
(b) Do not start the APU again until the fire department or the person(s) in charge have
given approval.
(7) Obey these APU exhaust precautions during refueling operations:
(a) The exhaust from an APU can cause a fire or an explosion if the exhaust stream
enters a flammable vapor zone (wing vent areas, fueling stations and the area
around fueling vehicles).
(b) Make sure the fuel vehicles are in a position that avoids any risk of being in the path
of the APU exhaust stream.
(c) Make sure the APU exhaust on the airplane that is refueling does not impinge on the
flammable vapor zone of another airplane. SERVICINGSERVICING
