aircraft and can withstand the impact forces encountered in shipment without damage or permanent deformation. The power plant/power unit shall be equipped with tiedown and slinging provisions.
3.9.1 Tiedown provisions. The tiedown provisions shall conform to MIL-STD-209, class 2 or 3, type II equipment, and to MIL-STD-1791 for equipment resistant criteria. The tiedown provisions shall satisfactorily complete the pull testing
as specified without weld failure, permanent deformation, cracking, loosening, or breaking of the provision or its connecting structural components.
3.9.2 Slinging provisions. The slinging provisions shall conform to
MIL-STD-209, class 1 or 3, type II. The provisions shall enable the complete power plant/power unit to be lifted, in the normal operating position. The provisions shall be located so that not less than 1-inch clearance is maintained between slings and all exterior parts and shall be fastened to members which will withstand stresses in the amount and direction of pull specified for the provisions without weld failure, permanent deformation, cracking, loosening, or breaking of the provision or its connecting structural components. Slinging provisions may also be used as tiedown provisions when such provisions meet the
requirements specified in 3.9.1. All slinging/tiedown provisions shall be labeled "LIFT", "TIEDOWN", or "LIFT TIEDOWN', as appropriate, in 1-inch (2.54 cm) high letters.
3.9.3 Air transportability. The power plant/power unit shall meet the requirements of MIL-STD-1791 for air transport. The power plant/power unit being supplied can be loaded, transported in the C-130, C-141, C-6A aircraft, and lifted by helicopters (see 6.13).
3.9.4 Rail transportability. The power plant/power unit shall be rail transportable in CONUS and NATO countries without restrictions. The power plant/power unit shall have a dimensional profile within the Gabarit International de Chargement (GIC) in accordance with the AAR manual, outline diagram when loaded on a 50-inch (127 cm) high rail car. The power plant/power unit shall be capable of withstanding shock loads resulting from rail impact testing in accordance with
4.6.3 without failure, damage, or permanent deformation.
3.9.5 Highway transportability. The power plant/power unit, when loaded on a semitrailer/tractor, shall be within the highway permit limits of all states.
3.10 Workmanship. Workmanship shall be of a quality to assure that the power plant/power units are free from defects resulting from defective material, incorrect manufacturing or assembly practices, incorrect treatment and painting, incomplete welds, rust, cracks, and other defects that could impair their operation or serviceability. MIL-STD-454, requirement 9, shall apply. External surfaces shall be free from burrs, sharp edges, and corners except when sharp edges and corners are specified on the applicable drawing.
3.10.1 Welders and welding operators. Before assigning any welder or welding operator to manual welding work covered by this specification, the contractor shall obtain certification that the welder has passed qualification tests as
prescribed by either AWS D.1, D 1.2, or the ASME code for the materials joined and the type of welding operation to be performed and that such qualification is effective as defined. Contractors who only make horizontal welds need not qualify
