A-A-59576 July 20, 2004 COMMERCIAL ITEM DESCRIPTION TOW BAR, FOR AIRCRAFT TOWING (KC-10 Aircraft) The General Services Administration has authorized the use

3、 of this commercial item description by all federal agencies. 1. SCOPE. This Commercial Item Description (CID) covers the KC-10 tow bar, which is used for towing and steering the aircraft by attaching it to the aircrafts nose landing gear and being pulled by a tow tractor. It will be used to move ai

4、rcraft to various locations around the flightline without powering up the aircraft and to egress and regress aircraft from hanger facilities. The tow bar, once attached to the aircraft nose landing gear (NLG) strut, will then be attached to powered tugs to facilitate movement on the flightline. 2. S

5、ALIENT CHARACTERISTICS. 2.1 Functional Requirements. The tow bar shall be suitable for its intended use. Structural elements shall be rigid and possess the requisite strength. Individual components shall be durable, reliable and suited for their intended purpose. Service and parts shall be readily a

6、vailable for all components. The tow bar must be able to pull an aircraft weighing 590,000 pounds (265,500 kilograms) without any deformation. 2.2 Interface. The interface requirements shall be as specified in table I. TABLE I. Interface requirements. OVERALL LENGTH 129.100 INCHES NOMINAL SPECIAL FE

7、ATURES 32.000 IN.HEIGHT; 34.000 IN.WIDTH; 480 LBS. TOWED END CONNECTION TYPE LUNETTE EYE TOWING END CONNECTION TYPE HOOK WITH LOCKING PIN WHEEL QUANTITY TWO (2) LENGTH ADJUSTABILITY NONADJUSTABLE 2.3 Standard Commercial Unit. The tow bar unit shall, as a minimum, be in accordance with the requiremen

8、ts of this specification and shall be the contractors standard commercial product. Additional or better features which are not specifically prohibited by this specification, but which are a part of the contractors standard commercial product, shall be included in the tow bar being furnished. The use

9、 of standard parts shall be maximized where they suit the purpose. INCH-POUND Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-59576 2 2.4 Materials. Selection of materials, processes, and parts utilized in the design and construction of the tow b

10、ar shall meet the best commercial practices and quality, unless otherwise noted, and shall be commensurate with the overall operational and performance requirements specified herein. The materials shall be of uniform quality and condition, free from any defects that may adversely affect appearance,

11、strength, endurance, wear resistance, and/or serviceability. Parts that are subject to corrosion in a marine environment shall be aluminum flame sprayed, zinc galvanized, or constructed of stainless steel, brass, bronze, or other corrosion resistant material. Unless protected against electrolytic co

12、rrosion, dissimilar metals, as defined in MIL-STD-889, shall not be used in intimate contact with each other. 2.5 Design. The tow bar body consists of a cylindrical body. At one end of the tow bar is a lunette eye, to which the tow tractor connects. At the opposite end of the tow bar is a mecha nica

13、l head assembly, to which the aircraft front landing gear connects. The tow bar shall be equipped with a wheeled undercarriage to serve as the means to make vertical height adjustments while attaching the end connection. The undercarriage shall be extendable by the use of either a mechanical device

14、or a hydraulic pump and cylinder arrangement. If a hydraulic arrangement is selected, the undercarriage shall retract automatically by spring or other mechanism upon release of hydraulic pressure. The wheels as well as any protruding stands shall clear level ground by a minimum of 4.0 inches during

15、towing operations. The unit shall permit easy accessibility for maintenance and service. The construction shall be such as to prevent conditions hazardous to personnel or detrimental to equipment. 2.6 Safety. The tow bar shall have an axial load limiter that fails at 83,700 lb drawbar pull. The load

16、 limiter shall be a shear pin type device. Equipped with a shear pin designed to break under excessive load. The shear pin will break before damage to the aircraft can occur. Shear pin failure is indicated by a sudden jerk of the tow vehicle and by an audible snap. The tow bar shall also have a load

17、 limiter device to limit torsional loads on the NLG strut to 350,000 inch pounds. The load limiter shall be a shear pin type device. Upon overload of the axial or torsional shear pin, the load shall be transferred to retaining bolts that prevent separation of the aircraft from the towing vehicle. Fo

18、llowing a shear pin failure, the tow bar must be taken out of service for shear pin replacement. As a safety feature the tow bar shall have a minimum factor of safety of 3.0 against permanent deformation at the loads applied above. 2.7 Storage. Storage shall be provided on the tow bar for a spare se

19、t of shear pins for each shear pin device. The tow bar shall be delivered with a full set of spares in place. 2.8 Corrosion Resistance. Materials used in the construction/design must be corrosion resistant to support worldwide deployment scenarios. Corrosion/deterioration prevention and control for

20、the tow bar shall be in accordance with best commercial practices. 2.9 Finish. Unless specified in the contract all painting and finishing shall be in accordance with the best commercial practice in the industry. All painted surfaces shall be color number 24052 (olive drab green) per FED-STD-595. Al

21、l finishing processes utilized in the design and construction of the unit shall result in a durable, non-fading, long lasting finish. Finish warranty shall be equivalent to best commercial warranty offered or a minimum of 3 years, whichever is greater. Warranty is not to include damage caused by com

22、mon maintenance activities. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-59576 3 2.10 Maintenance.
