 TASK 09-10-00-582-001
 1.  Towing
______
 A.  General
 (1)  
The design of the airplane will permit you to tow the airplane from the nose or main landing gear. The tow fitting on the nose gear can be used to tow the airplane with a tow bar. The maximum normal towing turning limits are indicated by the painted stripes on the nose gear doors.

 (2)  
You can tow the airplane on firm and level terrain by the nose gear with one tire flat on each landing gear if the starting loads are held to the minimum. For other unusual towing loads, such as towing with two flat tires on one main gear, towing on soft terrain, or towing up inclines greater than 5 degrees, you should tow the airplane from the main gear as the structural limitations of the nose gear may be exceeded.

 NOTE: With two flat tires on one main gear, you should replace
____ one of the flat tires with a serviceable tire before towing to prevent damage to the tires and wheels.
 (3)  
Towing the airplane with either or both engines removed is not a problem if you make sure the center of gravity remains forward of the aft center of gravity limits. Refer to the Center of Gravity Calculations for Towing task, for center of gravity data.

 (4)  
You can use towbarless equipment to push or pull the airplane. Make sure the maximum permitted loads on the landing gear are not more than the Maximum Towing Loads as shown in Fig. 202.

 NOTE: This procedure is for towing or pushing the airplane with a
____ tow bar. However, most of the steps in this procedure will apply if you use towbarless equipment. Refer to the equipment manufacturers data for procedures that are specific to their equipment.
 (5)  Boeing recommends towbarless tow vehicles be designed, tested, operated, and maintained per the following Society of Auromotive Engineers (SAE) Aerospace Recommended Practices (ARP), and applicable Boeing documentation:
 NOTE: Airplanes must insure the latest revisions of the standards
____
 and documents are applied.

 (a)  Towbarless tow vehicles documents and standards:
 1)  SAE ARP 4852: Specification for Towbarless Push-Back Tow Vehicles.
