Special Packaging Instruction Summary

This document is a Special Packaging Instruction (SPI) specification for an electro-mechanical actuator item (Part Number R1487M2-1, National Stock Number 1680-01-149-3166). The specification details the preservation, packing, and shipping requirements for the actuator using military standards. The item must be preserved using IAW MIL-STD-2073 with serviceable method 42 and unserviceable method 10. Cleaning and drying procedures follow IAW MIL-STD-2073, with no preservative required. Marking requirements are specified under IAW MIL-STD-129. The packing configuration uses two levels: Level A (basic packing) and Level B (expanded detail packaging per revision A). Level B specifies a container with interior dimensions of 24 inches length by 23 1/2 inches width by 18 3/4 inches depth, weighing 43.5 pounds gross, with design fragility classification G. The closure method for Level A uses no specific standard, while Level B employs IAW ASTM-D-1974.

The packing assembly for Level B consists of 15 component parts arranged in a specific layered configuration. Core components include a 24" x 23 1/2" x 18 3/4" container (Item 1), a bottom pad, die-cut separators (multiple pieces with 1" and 3" chamfers on opposite corners per specific dimensions), side cushioning, end cushioning, top and bottom cushioning components, wrap material, barrier material, and a carton interior dimension specification. The actuator itself requires 1" chamfers to ensure correct die-cut orientation and 3" chamfers on opposite corners. All adhesives, cushioning materials, and supporting components are specified with detailed cross-references to military specifications (MIL-PRF and A-A standards) for material quality and performance standards. The revision history shows the specification was initially established on 14056 with an expanded detail revision A on 14153.
