INTRODUCTION GENERAL DESCRIPTION GENERAL The main differences of the B737 Next Generation (NG) are as follows: Performance: Faster cruise M0.78 Higher ceiling 41,000ft Lower take−off & approach speeds Higher MTOW Lower fuel burn Engines: FADEC controlled CFM56−7 2.5deg nozzle tilt Redesigned struts Improved nacelles with increased airflow and improved noise treatment 7% more fuel efficient than CFM56−3 Fuselage: Strengthened for increased tail loads and design weights New wing−body strake

Flight Controls: Increased elevator PCU capability Aileron and tab span increase New double slotted continuous span flaps New leading edge Krueger flaps Additional slat Additional spoiler Nose Gear: Stroke increased 3.5” to relieve higher dynamic loads and wheelwell extended 3” forward. Main Gear: Longer One piece titanium gear beam 43.5” tyres Digital antiskid Flight Deck: 6 programmable LCD’s, replacing most conventional and early generation EFIS CRT displays.

Wings New airfoil section 25% increase in area 217” (5.4m) wing−span increase 17” (0.43m) chord increase Raked wing−tip Larger inspar wingbox with machined ribs mIncreased fuel capacity (4500kg) Tail: 4ft 8in taller 60 sq ft root insert

ISSUE 1, 06 Jan 2014

Systems: Most systems developed particularly: electrics, powerplant & navigation. Commonality The B737 NG is designed to be common with the B737 Classic. Because both airplanes have the same flight deck layout and airplane handling characteristics, the flight crews can be common type rated. In addition, there is substantial component commonality between these two models.

BOEING 737 -600/700/800/900 PRINCIPAL CHARACTERISTICS The design of the B737 NG (Next Generation) is based on the B737 Classic family: Boeing 737-300/-400/-500. The Boeing B737 NG is a twin engine airplane. It is designed for short to medium range operation and consists of four models: ● B737−600 ● B737−700 ● B737−800 ● B737−900 In this document, the use of the designator B737 NG without a reference to a specific model indicates that this information applies to all four models. The Boeing 737 NG program was launched in June 1993, starting with the B737−700 (22cm (9in) longer than the original B737−300 and a seating up to 149). The B737−800 project was launched in September 1994 and is based on the B737−400 but is significantly longer at 39.4m (129ft 6in) and seats up to 189. The −800 has been available with winglets since May 2001. These reduce aerodynamic drag thereby reducing fuel consumption by up to 7%. The B737−600 was the third of the NG’s to be built and started in March 1995 and originated as the B737−500 with a similar length fuselage, seating between 108−132. Boeing began work on the stretched B737−900 in April 1997 and opted to use the same (-800) emergency exit layout, with 4 main exit doors and 4 overwing exits, thereby still restricting the maximum passenger load to 189.

07. JACKING (ATA07) Jacking Points The airplane has three main jack points and four auxiliary jacking points. The main points are wing jacking points A and B and aft body jacking point C. The four auxiliary points are forward body jacking point D and three landing gear points E (Nose) and F (Main Landing Gear). The airplane may be jacked at any gross weight provided the maximum load of any jacking point is not exceeded. If the airplane is supported entirely by the three main jacks and the stabilizer jack at point D, the maximum jacking weight of the airplane must not be exceeded (see AMM 07−11). Axle jacking points E and F provide the means for changing two flat tires on the same axle up to maximum gross taxi weight. Landing gear jack points are integral 3/4 inch spherical radius pads under main and nose gear axles. The jacking points on the wing and body include special provisions for the attachment of bolt-on type jack adapters provided with 3/4 inch spherical radius pads. To minimize the vertical lift during the jacking operation, main and nose gear shock strut restrainers which lock the oleos in a de-pressurized and compressed condition may be used if gear retraction is not the reason for jacking. Caution:

DO NOT LIFT THE AIRPLANE ON JACKS IN WINDS MORE THAN 35 KNOTS. IF YOU DO NOT OBEY THESE INSTRUCTIONS DAMAGE TO THE AIRPLANE CAN OCCUR.

Level the Airplane with a Plumb Bob Make sure the airplane is parked in the most level position available. Attach a plumb bob and chord in the right main wheel well to the bracket that shows the words „LEVEL HERE“. The bracket is directly above the leveling scale. The plumb bob chord must be on the outboard side (decal side) of the support bracket. The plumb bob must be clear of the target by less than 1/8 inch. Examine the position of the plumb bob when it does not move. If the plumb bob is not in the zero position on the leveling scale, make the airplane level. ISSUE 1, 06 Jan 2014

09 TOWING and TAXIING (ATA09) Precautions AIRCRAFT TOWING The nose gear has a forward tow fitting. Each main gear has both a forward and an aft tow fitting. The main gear tow fittings are for abnormal towing conditions.

Tip clearance requires special care during the turn. Airplane should be moving before turning the nose wheel. Airplane nose wheel should be fore and aft prior to parking.

A placard describing towing operations is below the towing lever.

Warning: MOST TOWBARLESS TOW VEHICLES DO NOT HAVE A

To tow the aircraft the towing lever must be held in the tow position with a lockpin. In this position, hydraulic pressure for nose wheel steering is locked out. A red stripe on each nose wheel well door identifies the 78 degree position. Maximum nose gear steering angle is 78 degrees, with the torsion links connected. If the steering angle is to exceed 78 degrees, disconnect the torsion links. Make sure you have the necessary clearance when you go near a parked airplane or other structures. When the APU in the towed airplane or a parked airplane is on, you must have a minimum clearance of 32.8 feet (10 meters).

SHEAR PIN TO LIMIT THE LOADS IF THE AIRPLANE BRAKES ARE USED DURING TOWING. DO NOT APPLY THE AIRPLANE BRAKES WHEN YOU TOW THE AIRPLANE WITH TOWBARLESS TOW VEHICLES. IF YOU APPLY THE BRAKES, YOU CAN APPLY LOADS TO THE NOSE LANDING GEAR THAT ARE MORE THAN THE DESIGN LOAD LIMITS. IF YOU DO NOT OBEY THIS CAUTION, DAMAGE WILL OCCUR TO THE NOSE LANDING GEAR, THE TOW VEHICLE, AND MAINTENANCE PERSONS CAN BE INJURED.

The clearance must be between the APU exhaust port and the adjacent airplane’s wingtip (fuel vent). To tow the airplane with the entry or the cargo doors open is optional. Towbarless Towing Towing stability of a Towbarless Tow Vehicle (TLTV)/Airplane combination is dependent on many variables, two of these key variables being the characteristics of the tow vehicle attractive forces and the runway conditions. Maximum towing speeds shall be the responsibility of the airplane operator in conjunction with the airport authorities with consideration of recommendations from the TLTV manufacturer.

TAXI THE AIRPLANE (ATA09-20) – MAINTENANCE PRACTICES

Maintenance Persons Necessary to Taxi the Airplane

Warning: Refer to the Operations Manual to taxi the airplane for revenue service.

The persons necessary for a safe taxi operations must include a flight compartment crew and a ground crew. There must be a minimum of two flight compartment persons (One taxi approved person and one observer).

Taxi Safety When you taxi an airplane, caution and precision are necessary. The taxi procedure must be done only by persons that are trained to taxi the airplane. The taxi path must be clear of all persons and vehicles. You must get approval from the airport ground control to taxi the airplane. You must keep clearance from the buildings and the other airplanes, at all times. You must have electrical power to operate: - the taxi lights - the navigation lights - the radio and intercom equipment - other necessary systems. Check for a fuel imbalance condition. Note: If an aircraft was moved (tow or taxi) with a lateral fuel imbalance in excess of AMM limits while on the ground, a structural inspection is not required provided normal taxi procedures were followed, the maximum taxi speed was below 25 knots and no hard braking or maximum braking occurred. If these limitations were exceeded a structural inspection is required, contact engineering for a specific bill of work. The applicable airplane hydraulic systems must be pressurized to supply hydraulic pressure. When you taxi the airplane at night or in bad weather conditions, the crew must know the area around the airplane. A taxi checklist is necessary to help the crew have a safe taxi operation.

ISSUE 1, 06 Jan 2014

One flight compartment person must be trained in all of the procedures that follow, for the taxi operations: Note: It is not necessary for the observer to be taxi approved. Correct procedure to prepare the flight compartment The engine start, operation, and shutdown procedures The engine fire and emergency procedures The radio and intercom operation and procedures The taxi procedures (turning, wing tip clearances, taxi speeds, etc) One or two ground crew persons are necessary to do the tasks that follow: Note:

In areas of congestion or a limit of space (hangers, ramp areas next to the terminal, airplane parking areas, etc.) more ground persons are necessary. This is to help monitor the wing clearances and to be general observers. To remove and replace the wheel chocks To help during the engine start To help the flight compartment crew during the airplane movement To make sure the airplane taxi path is clear.

Communications Most areas around the airplane are out of the field of view permitted by the flight compartment windows. Also, it is hard to see much of the ground operations work near the airplane from the flight compartment crew. There must be communication between the airplane and the ground crew. This is necessary during the engine start, removal and replacement of wheel chocks, and during the engine shutdown. To have a safe taxi operation you must use hand signals, lights, intercom and/or radio communication. The communications with the ground control authority is also necessary for taxi operations.

Taxi the Airplane When you taxi the airplane on the ground, the movement is equivalent to other conventional tricycle geared airplanes. The nose wheel steering, and the engine thrust are used as necessary, to taxi the airplane. 1.

2.

3.

Airplane ground stability - During the airplane taxi, the center of gravity (CG) must always be below the Ground Stability Limits line, (see, AMM 09-11-00 for more information). Find the airplane center of gravity (CG) for the applicable airplane configuration. Use component weight and CG data, and the procedures to calculate them, in the approved weight and balance manuals. Airplane clearance during the taxi - Make sure you have the necessary clearance when you go near a parked airplane or other structures. When the APU in the taxi airplane or the parked airplane is on, you must have a minimum clearance of 32.8 ft (10.0 m). The clearance must be between the APU exhaust port and the adjacent airplane’s wingtip (fuel vent). Airplane taxi speed - The taxi speed must not be more than approximately 20 knots. Speeds more than this, added to long taxi distances will cause heat to collect in the tires. Before you make a turn, decrease the speed of the airplane to a speed which is applicable to the local conditions. On a dry surface, use a speed of approximately 8 to 12 knots. Airplane turns during taxi. Always use the largest turn radius possible. Do not try to turn the airplane until it has started to moved. Make sure you know the taxi turn radii, (see AMM 09-11-00 for more information). Monitor the wingtips and the horizontal stabilizer carefully for clearance with buildings, equipment, and other airplanes. Make all turns at a slow taxi speed to prevent tire skids. When a left or right engine is used to help make a turn, use only the minimum power possible. Do not let the airplane stop during a turn. Do not use the brakes to help during a turn. Decrease the speed of the airplane with the brakes when it is necessary, before the turn is started. Make a minimum radius turn with maximum nose wheel steering, and the engine thrust only. When you use the brakes during a turn, they will cause the main and nose landing gear tires to wear. ) When it is possible, complete the taxi in a straight line roll for a minimum of 12 ft (4 m).

ISSUE 1, 06 Jan 2014

Note:

This will remove the torsional stresses in the landing gear components, and in the tires.

Note:

The wingtips and the horizontal stabilizer move in larger arcs during a turn than the nose of the airplane. You must monitor these areas of the airplane carefully for clearance with buildings, equipment, and other airplanes.

The basic factors that can change the diameter of a turn are as follows: the nose wheel steering angle the engine power the center of gravity of the airplane the airplane gross weight the taxi surface conditions the airplane ground speed the differential braking that you use.

10. PARKING AND MOORING (ATA10) PARKING - MAINTENANCE PRACTICES

Warning: PITOT PROBE COVERS AND STATIC PORT COVERS ARE RECOMMENDED WHEN THE AIRPLANE IS PARKED FOR MORE THAN A STANDARD TURNAROUND OR WHEN CONDITIONS SUCH AS INSECT ACTIVITY, DUST STORMS, ICE, SNOW, OR VOLCANIC ASH MAY INCREASE THE RISK OF PITOT PROBE OR STATIC PORT CONTAMINATION. A PITOT PROBE OR STATIC PORT SYSTEM BLOCKED BY FOREIGN OBJECTS SUCH AS INSECTS MAY CAUSE LARGE ERRORS IN AIRSPEEDSENSING AND ALTITUDE-SENSING SIGNALS, WHICH MAY LEAD TO LOSS OF SAFE FLIGHT.

A static ground on the airplane is not necessary when the airplane is parked or is serviced during the turnaround operation. This does not include when specific maintenance steps are done.

NORMAL PARKING AMM 10-11-00

Pitot probe and static port covers are recommended when the airplane is parked for more than a standard turnaround. Failure to remove coverings from static ports or covers from pitot probes before flight may cause large errors in airspeed-sensing and altitude-sensing signals, which may lead to loss of safe flight.

PROLONGED PARKING AMM 10-12-00

If the temperature of the fuel is below 32°F (0°C), do not to drain the fuel tank sumps. To check for water at the fuel tank sump drain valves with fuel temperature below 32°F (0°C), do one of the following to raise the temperature of the fuel: fill the tanks with warm fuel move the airplane in to a warm hangar.

HIGH WIND CONDITION MOORING AMM 10-21-00

PRESERVATION PROCEDURES - QUICK CHECK

When the airplane is initially put into storage, necessary to complete storage preparation maintenance tasks. During the storage will do the tasks for service and protection on the appropriate cycles. The prolonged parking procedure is not intended for use on aircraft that are out of service for maintenance or modification reasons only. However, this procedure can still be used as a guide for an airplane in maintenance or modification if the systems that will be impacted are evaluated, and any necessary changes to the procedure are made, based on the unique airplane configurations that are encountered during the maintenance or modification period. When an airplane is not operated for 7 days or more, the airplane must be protected. The procedures that follow will prevent the deterioration of the airplane structure, finish, or system components. There are different procedures to prepare some systems for storage. These procedures are calculated by the length of time the airplane is to be in storage. The airplane storage times are categorized as follows: Short Term Storage - applies to times that are 0 to 60 days unless specified differently Long Term Storage - applies to times that are more than 60 days unless specified differently. More details about Prolonged Parking see AMM 10-12-02.

MOORING (Parking in High Winds) The airplane is made to be resistant to high velocity ground winds from all angles without mooring. However, when airplane configuration and expected high wind conditions are in the "EXTREME CAUTION ZONE" according to AMM 10-11-03. It is recommended to move the airplane to a safe location. If the airplane cannot be moved, moor/ secure the airplane. Here is not specific values of wind velocity for High Wind conditions. When you think it is necessary to do special mooring because of strong winds. Mooring at the wheels will decrease the airplane movement. It will also decrease the risk of structural damage. Note:

Close all the doors and hatches. Make sure that all the covers and plugs are tightly held in their positions. Attach nose and main gears mooring straps and shackles around each landing gear shock strut parallel to the airplane y-axis as shown in figure Attach the tie down equipment to the landing gear mooring equipment. Attach the other ends of the tie down equipment to the ground anchor points. Make sure all the mooring straps have equivalent tension . Make sure there is no equipment in the area that can move during the strong wind and cause damage to the airplane.

Refer to AMM 10-11-03 for the effects of wind on the airplane. To reduce airplane movement, snow and ice must be removed from the surface below the wheels.

Mooring the airplane utilizes ground anchor points and tie down equipment. The tie down equipment is customer furnished and may be any combination of components (i.e. shackles, chain, or cable) that meet the load requirements stated in the procedure. Following procedures must be completed for prepare to mooring: Park the airplane, do this task, except that the parking brake must be on. Caution:

THE PARKING BRAKES WILL HAVE AN EFFECT FOR 8 HOURS AFTER THEY ARE SET. BEFORE THE 8 HOURS ARE DONE, YOU MUST RELEASE AND SET THE PARKING BRAKE AGAIN. THIS WILL MAKE SURE THERE IS SUFFICIENT HYDRAULIC PRESSURE. IF THERE IS NOT SUFFICIENT HYDRAULIC PRESSURE, THE AIRPLANE CAN MOVE AND CAUSE DAMAGE TO THE AIRPLANE.

Make sure the flaps are in the full up position to decrease the wing lift. Fill the airplane to its maximum fuel capacity and move the CG fully forward. MOORING AIRCRAFT ISSUE 1, 01 Jul 2013

AIRPLANE GROUNDING - MAINTENANCE PRACTICES General This procedure contains these tasks: Static Grounding Electrical Bonding Measurement of Airplane Electrical Resistance to Ground If operators choose not to do these recommended tasks, they should develop alternate procedures which adequately protect personnel and equipment. Local fire codes and customs may require alternative or additional procedures to those shown here. Static Grounding (TASK 20-40-11-910-801) The airplane is normally electrostatically grounded through conductive tires (Refer to the task, Measure Electrical Resistance to Ground). However, static grounding is necessary for: Airplanes having inadequate conductivity to ground through the tires. Airplanes on parking sites that have inadequate conductivity.

Static grounding is not necessary if the airplane is parked for turnaround flight and no maintenance is to be done. During pressure refueling of the airplane an electrical bond is necessary between the airplane and the refueling vehicle. Static grounding is not necessary as long as the conductivity of the airplane Warning: DO NOT WEAR HEADSET OR HANDLE ANY UMBILICAL CONNECTIONS TO AIRPLANE DURING ATMOSPHERIC ELECTRICAL DISTURBANCES. LIGHTNING STRIKE CAN CAUSE SEVERE INJURY. Warning: ALWAYS ATTACH THE GROUNDING CABLE TO THE GROUND CONNECTION FIRST. NEVER ATTACH THE CABLE TO THE AIRPLANE AND THEN TO THE GROUND CONNECTION. Caution:

The operator must ensure that the conductivity of the airplane and the parking site are adequate and may need to establish local procedures in area where inadequate parking site conductivity is seasonal or permanent. Static grounding is necessary when performing maintenance tasks using these devices: power tools electrical power sources lights powered instruments flammable conditions (such as painting and solvent application) When static grounding is recommended in a detailed procedure, the airplane must be statically grounded to a common, approved, identified ground

ISSUE 1, 01 Jul 2013

ATTACH GROUNDING CABLES ONLY TO SPECIFIED POINTS ON THE AIRPLANE. INCORRECTLY ATTACHED GROUNDING CABLES CAN CAUSE SCRATCHES WHICH CAN CAUSE CORROSION AND CRACKS ON STRESSED PARTS. GROUND WIRES ATTACHED TO DOORS OR FAIRINGS MADE FROM COMPOSITE MATERIALS DO NOT PROVIDE A GROUND.

Static grounding procedure must be carry out in the following sequence: Connect the grounding cable to an approved, identified static ground point. Note:

These points may be located in the parking surface or in another fixed location.

Connect the grounding cable to approved grounding attach point on the airplane . Before the airplane is moved, remove the ground cables in reverse sequence of attachment.

Handling Printed Circuit Cards

Handling Computers

When replacing printed circuit cards, remove electrical power on the applicable system. Wear a wrist strap that is properly grounded. The wrist strap prevents a build−up of electrostatic charges. The wrist strap has a 1 meg ohm safety resistor to prevent electrical shock if you touch a high voltage source, such as 115 volts AC. Put the card into a printed circuit card carrier or a special conductive bag. Close the bag with an ESDS (Electrostatic Sensitive Devices) label.

When replacing computers, remove electrical power on the applicable system. A wrist strap need not be worn. Remove the computer without touching the connectors on the back and install Conductive caps. The conductive caps prevent an electrostatic discharge from reaching the pins in the back of the computer. For more detailed information on the safe handling of ESDS devices refer to Maintenance Manual (MM 20−10−07).

SAFETY ITEMS/INTERFACES GENERAL B2: Mechanical Interface General safety Precautions General safety precautions are part of module 7 ”Maintenance Practices”. Specific safety Precautions For each aircraft type, there are some special safety precautions. This requires special awareness for safety during operation or when a task is performed. The identification of safety relevant will be discussed in the Training Manual for the related aircraft system. Additionally, in the Training Manual for aircraft documentation shows how safety items are identified in the Aircraft Maintenance Manual. B1: Avionics Interface For mechanical systems which interface with avionic systems, some selected safety items are listed here: When the aircraft is fuelled or defueled, Weather radar and HF must not be used. When any task of an aircraft system requires the Air/Ground System to be set to the Flight condition, probe heating systems and many other systems are also affected.

For avionic systems which interface with mechanical systems, some selected safety items are listed here: When Auto Flight Systems are operated or tested, electrical actuators may start operation. With hydraulic power active, hydraulic actuators may also start operation. Keep surfaces clear. This may affect automatic slat systems and automatic ground spoiler systems. When any task of an aircraft system requires the Air/Ground System to be set to the Flight condition, many other systems are also affected. Note the safety items for the air/ground sensing system. HF must not be used when the aircraft is fuelled or defueled. Weather Radar must not be used when the aircraft is fueled or defueled. Some systems may operate depending on airspeed. When air data test equipment is used, this all consequences must be regarded.

Note the safety items for the air/ground sensing system.
