About this file
This is an Engineering Change Proposal (ECP) numbered I13091 that documents revisions to multiple engineering drawings related to foam cushion components and spacers. The ECP affects nine drawings across two CAGE codes (53711 and 53711), including cushion spacer assemblies, individual cushion parts, and nose cushion variants.
The primary changes standardize documentation across all affected drawings by: (1) replacing existing notes with current PHST Center format for foam cushion material specifications, increasing major characteristics from two to three and renumbering accordingly, with lamination requirements added as a new major characteristic; (2) updating dimensioning styles from aligned to coordinate format with contour coordinate tables for clarity on select drawings; (3) modifying reference note citations throughout (e.g., from "SEE NOTE 2" to "SEE NOTE 3"); (4) redistributing parts list items, removing items from parts lists and relocating them to notes sections; (5) revising material block designations by removing "ALL MATERIAL (M101)" and placing "(M101)" next to Item 1 of parts lists; and (6) changing distribution statements from "Distribution Statement D" to "Distribution Statement A - Approved for Public Release; Distribution is Unlimited" on applicable drawings. Additional updates include adding lamination direction indicators, incorporating anti-static foam specifications, and establishing new density and compression strength parameters for polyethylene foam materials per Federal Specification PPP-C-1752. No new drawings are being added or deleted from the package, and no outstanding RFDs/RFWs/ECPs are being incorporated.
