This document is a technical specification and design drawing for a Metal Bonded Course Training Edge Panel intended for repair training purposes.

The panel specifications detail an aluminum skin and honeycomb sandwich construction with final requested dimensions of 30" x 7.5" x 2". The bottom skin consists of .020" material per 2024-T3, NSN 9535-00-167-2277, while the top skin uses the same material and specification. A .020" shim material (NSN 9535-00-167-2277) is also required. The core material is aluminum for sandwich construction per MIL-C-7438G, with core material type 4.5 - 1/8" .001" N - 5056. Internal, external skins, and shim components must be bonded with film adhesive equivalent to BMS5-154 TY2 CLI GR5. The panel features a 7.25" dimension width, 7.5" length, and 2" height, with a 30-degree trailing edge angle. Panel overall width and length dimensions maintain ±.125 tolerances. The second page illustrates the trailing edge repair construction, showing component layers including an overlay patch, film adhesive, core plug, core splice with foam adhesive, edge doubler, internal doubler, and filler materials that comprise the repair methodology for this training panel.
