COMMERCIAL ITEM DESCRIPTION

SPRAYING UNIT, CLEANING-DEICING- ANTI-ICING FLUID, TRUCK MOUNTED

The General Services Administration has authorized the use of this

Commercial Item Description (CID) for all Federal agencies.

1. SCOPE. This CID describes chassis mounted, diesel powered, spraying units, which are capable of deicing, anti-icing, cleaning, and decontaminating the entire range of airframes in the U. S. Air Force’s inventory. Two general classifications are herein defined: (1) a basic unit, Class A, that can de/anti-ice and clean all but the upper tail sections of C-5 and C-17 airframes; and, (2) a spraying unit, Class B, provided with the extended reach necessary to effectively de/anti-ice C-5 and C-17 horizontal stabilizers. Both Classes of spraying units include boom-mounted enclosed cabs from which de/anti-icing and decontamination operations are performed. The spraying units are capable of the controlled application of heated deicing fluid, deicing fluid delivered via forced air and/or high efficiency nozzles, and unheated anti-icing fluid. An auxiliary power transmission source such as an engine or hydrostatic drive is provided to hydraulically operate all de-icing components including boom and enclosed cab actuation, deicing-fluid heater motor and fuel pump, and separate deicing and anti-icing pump motors.

2. CLASSIFICATION. The two Classes of spraying units covered by this CID are classified as follows:

Class Elevation of boom Minimum Tank Capacity A 42 feet 1,600 gal B 75 feet 2,600 gal

3. SALIENT CHARACTERISTICS.

3.1 Spraying unit description. Both Classes A and Class B spraying units shall be constructed in accordance with the requirements of SAE ARP-1247, General Requirements for Aerospace Ground Support Equipment, Motorized and Non-motorized, SAE ARP-1971, Aircraft Deicing Vehicle – Self-Propelled, Large Capacity, and this document. In the event of a conflict between either ARP-1247 or ARP-1971 and the text of this document, this document shall take precedence.

Nothing in this document, however, overrides applicable laws and regulations, unless specific mailto:ENGINEERING.STANDARDS@US.AF.MIL https://assist.dla.mil/

Protective coatings that chip, crack, or scale with age or extremes of climatic conditions or when exposed to heat shall not be used. Fasteners, handles, and fittings used in the assembly of the item shall also be primed and painted.

3.2.1.2 Dissimilar metals. Dissimilar metals, as defined in MIL-STD-889, shall not be in contact with each other. Metal plating or metal spraying of dissimilar base metals to provide electromotive-compatible abutting surfaces is acceptable. The use of dissimilar metals is permitted only when separated by suitable insulating material, except in systems where bridging of insulation materials by an electrically conductive fluid can occur. Sealants or gel-type gasket materials shall be used between faying surfaces and butt joints.

3.2.1.1.1 Rustproofing. The vehicle chassis and cab (at minimum: seams, welds, locations where dissimilar metals contact, etc.) shall be rustproofed and undercoated in accordance with FED-STD-
