3 . Operating Procedures HALL Technical Services, LLC ALWAYS FOLLOW AIRCRAFT MANUFACTURERS PROCEDURES FOR PUSHBACK AND TOWING OPERATIONS.. Responsibility Operator of the tractor must understand that it is his/her responsibility to move the aircraft safely in accordance with the aircraft manufacturers operational procedures. Employer of tractor operator is responsible for providing sufficient operator training to ensure safe operation of towbar for pushback and towing operations The following are recommendations... Inspect the Towbar prior to each use:... Visually inspect shear pin for correct installation, damage, and that it is the correct shear pin marked 737/ABN (see image below). Shear pin may be gold or silver colored.... Visually inspect that Pivot and Capture bolt nuts are present on underside of adapter...3. Visually inspect towbar tube for cracks at welded joints...4. Visually inspect tow eye assembly for damage and loose or missing hardware...5. Visually inspect wheel carriage for damage and loose or missing components...6. Visually inspect adapter to tube flange bolts...7. Check head latch mechanism for proper travel and locking action in both forward and back positions. Inspect for damage and loose or missing components. WARNING: DO NOT attempt to tow an aircraft with a damaged towbar. TB 967 TOWBAR MANUAL Page 3

4 HALL Technical Services, LLC.3. Use the correct size Aircraft Tow Tractor: An important consideration for safe movement of an aircraft is using the correct category of tractor for pushback and towing operations. Incidents are more likely to occur when using a tractor that is either too large or too small for a particular aircraft. Consult the Aircraft Manufacturers Ground Towing Requirements chart to obtain tractor draw bar pull and total wheel traction requirements based on aircraft and environmental conditions. Category is recommended. Category Aircraft Maximum Takeoff Weight Tractor Draw Bar Pull Up to 50,000 kg (0,000 lbs.) 4,000 kg (8,800 lbs.) Up to 50,000 kg (330,690 lbs.),000 kg (6,455 lbs.) 3 Up to 60,000 kg (573,96 lbs.) 38,000 kg (39,683 lbs.) 4 More than 60,000 kg (573,96 lbs.) 440,000 kg (88,84 lbs.) Source: IATA "Airport Handling Ground Support Equipment" Specification AHM 955: "Functional Specification for an Aircraft Tractor".4. Attach towbar to aircraft first, then to tractor..5. Towbar should be horizontal to ground or up to " (5cm) higher at the aircraft end..6. Do not exceed a 90 degree angle between towbar and pushback tractor. Damage to towbar or aircraft can occur..7. Always start a pushback with the tractor in line with the towbar..8. Attach the Towbar to the Aircraft.8.. First check that the towbar head latch is in the open position..8.. Line up towbar to nose pin of aircraft and slide head under the nose pin Lower the handle and lock the jaw to the nose pin. Due to the over center arrangement of the clamping mechanism, the jaws remain closed until the handle is released by the operator. The head can only be disengaged by operation of the handle. If equipped make sure that the handle latch (P/N TB 83 LHA or P/N TB 83 LHA A) locking pin is inserted and is keeping the handle in the down position. Or if equipped make sure the automatic handle latch (TS 737 ASL) is functional..9. Attach the Towbar to the Tow Tractor.9.. Lift to the level of the tractor hitch..9.. Position the tractor and install the hitch pin Tow or push the aircraft only if the towbar's tires are not touching the ground. TB 967 TOWBAR MANUAL Page 4

5 .0. Push the Aircraft HALL Technical Services, LLC ALWAYS FOLLOW AIRCRAFT MANUFACTURERS PROCEDURES FOR PUSHBACK AND TOWING OPERATIONS NOTE: If at any time the shear pin yields or breaks, carefully bring the aircraft to a stop. Follow aircraft manufacturers and/or airline nose landing gear inspection procedures prior to installing a new shear pin to continue the operation. The following information is provided as general guidance only..0.. Prior to moving, make sure that full swivel release pins are released (if applicable)..0.. Double check that all the tie downs and chocks are removed Double check that aircraft brakes are released Tow Slow: max speed is a brisk walk (Approximately 5 MPH). This will help to minimize the chance of a jack knife event Do not exceed Aircraft nose wheel angle of towing limits. If not marked or not known, do not exceed 30 from center. Be extra cautious on snow and ice If you are driving make sure that you have plenty of help; wing walkers are helpful and may be required per airline or aircraft manufacturer procedures Ensure the operator has contact with the pilot at all times while moving the aircraft. NOTE: Thousand of dollars in damage can occur in a few seconds while towing. Most incidents are due to operator negligence / error. Accidents can be fatal... Disconnect the Towbar from the Tractor.. Disconnect the Towbar from the Aircraft... If equipped pull the locking pin or ASL and move the handle into the open position.... Carefully lower the towbar to the ground (use hydraulic lift if installed)...3. Move pushback tractor and towbar clear of the aircraft. TB 967 TOWBAR MANUAL Page 5

6 3. Preventive Maintenance HALL Technical Services, LLC NOTE: Hall Industries recommends using this maintenance procedure monthly (or as required by airlines maintenance procedures). Replace worn or damaged parts as needed. 3.. Replace Shear Pin. Shear pin should have a slight vertical play, spin freely and the nut should not be tight to the head. A very small gap (0.00" 0.00" feeler gage) between the nut and the head is required. See Figure below. Figure. Inspection of shear pin and head/adapter clearance. 3.. Check clearance between head and adapter. With the shear pin removed, the head must be able to slide and pivot within the adapter plates by hand. Tighten Capture bolt to shoulder. If head cannot be moved by hand back off until head can be moved. Insert shear pin and inspect per item 3. above. Tighten Pivot bolt to contact or shoulder and verify that head can still be moved by hand. If desired a dry lube can be applied to the sliding surfaces between the head and adapter Check Shear Pin Bushings. They should not be worn, cracked, or otherwise damaged. NOTE: Always replace bushings as a set. Never replace only one bushing Check adapter/tube flange bolts (TB 8898 ) for tightness. Torque to 50 ft lbs. TB 967 TOWBAR MANUAL Page 6

7 HALL Technical Services, LLC 3.5. Check wheels and wheel carriage for bent, broken, or worn parts and security. Lubricate pivot points using Hall dry lubricant (P/N TB LUBE) Check head assembly for operation of lock mechanism; look for bending, security, etc. Lubricate pivot points using Hall dry lubricant (P/N TB LUBE) Inspect jaw assembly for worn or damaged parts and security Check latch mechanism to ensure proper travel back and forth. Lubricate pivot points Check latch mechanism locking force. The release force on the handle is set at the factory to a minimum of 0 pounds when clamped to an aircraft replacement Nose Pin. When performing PM you can lock it on to a Test Pin (Part number SS 83) supplied by Hall Industries (do not use a regular hot rolled bolt as a test pin). To adjust the pressure, remove TB 83 J4, turn the Swing Bolt TB 83 J half of a revolution (clockwise to decrease pressure, counter clockwise to increase pressure), and replace and retighten TB 83 J4. Check the release force and repeat if necessary. With daily use some wear / increased clearances will be noticed. The components of this adjustment are available as a kit (see kit section). NOTE: When closing/ locking of the handle force is too light, the attachment to the aircraft nose pin will be sloppy and excessive play will result. This can result in the handle opening during a push and loss of aircraft control Check tow eye and hardware (Tractor attachment) for condition and security. 3.. Check main body tube for bending or cracking. 3.. If the drag plate is worn and towbar head or eye is dragging use replacement drag plate kit (Part number AV ) Clean, repaint or touch up paint as required Inspect tags and labels. If damaged or missing replace (see the drawings in the attachment section for labels and placements) If the towbar is equipped with a hydraulic lift, check the fluid reservoir (in the down / collapsed position). Add fluid (Automatic Transmission Fluid) if necessary. TB 967 TOWBAR MANUAL Page 7
