This is an Air Force Engineering Order (AFMC Form 3925) dated April 2, 2015, documenting an Advance Engineering Change Order (AECO) against an Air Force-owned drawing for a Sheave Casting component.

The engineering order modifies drawing number 201018857 (CAGE code 98752) for the Sheave Casting assembly 201018858-10, which is used on the BAK-12 AAS system. The change is classified as an "Updated Drawing" and involves a material specification modification at Location D4. Specifically, the change revises casting material requirements from aluminum alloy A356-T6 sand cast per ASTM B26/B26M to allow either aluminum alloy A356-T6 sand cast per ASTM B26/B26M or billet 6061-T6, while maintaining grade B or C per AMS 2175 and Class 1 casting inspection per AMS 2175. The document is one page of a multi-page engineering order and affects sheet 1 of 1 of the drawing. The distribution statement indicates the material is controlled under DoDI 5230.24 classification requirements.
