DD Form 2169 Special Packaging Instruction Summary

This is a DD Form 2169 Special Packaging Instruction document (dated 26 NOV 2025, Revision C) that specifies detailed packaging, preservation, and packing requirements for a Seat Kit, Troop, Dump (Part Number 57K 2015, CAGE 19207, National Stock Number 2540-01-497-3374). The unit pack weighs 742.0 pounds and measures 74.8 x 44.0 x 26.0 cubic inches. The kit is to be packaged in a Modified ASTM-D6251 Style A, Class 2 container sized 72-1/2 x 41-3/4 x 20-1/4 inches using MIL-STD-1186 cushioning, blocking, and bracing standards, with MIL-STD-2073-1 Level A packing and MIL-STD-129 marking requirements.

The kit contents list includes eight segregated pack numbers (SPNs) containing various components: support assemblies, backrests, post assemblies, adapter assemblies, safety strap assembly, troop seat installation documentation, and cable/alarm/tiedown strap assemblies. Detailed fabrication instructions specify creation of numerous wooden blocks and foam pads with precise dimensions, construction of tray assemblies using lumber, wire, and fasteners conforming to ASTM F1667 and FF-N-105 standards, and strategic placement of all components within the shipping container with specific wrap materials (MIL-PRF-121 and PPP-C-1797). Quality assurance requires inspection of preservation and unit packing per MIL-STD-2073-1, packing per MIL-STD-1186, and final assembly per Method 10 inspection criteria. The unit container serves as the shipping container, closed per ASTM-D6251 with a packing list identifying segregated pack contents per MIL-STD-129.
