1. WARNING - The documents listed on this Engineering Data List (EDL) contain technical data whose export is restrictive by the Arms Export Control Act (Title 22, USC, Section 2751, ET SEQ.), or the Export Administration Act of 1979, as amended, Title 50 U.S.C, Append 2401 ET SEQ. Violators of these export laws are subject to severe criminal penalties.

2. Contractor is responsible to completely research these manuals, specifications, and standards and fully understand the requirements necessary for manufacture of component parts and assemblies.

All deviations, minor and major, from the engineering drawing package shall be submitted to the proper A-10 engineering organization for coordination and approval.

3. When military documents listed in the engineering drawing are cancelled they shall be replaced by the industry equivalent document specified on the military document's cancellation notice. The characteristics of type, grade, class, etc. specified in the cancelled military document shall be maintained or exceed those characteristics when applying the industry equivalent document(s). The contractor will coordinate with the proper A-10 engineering organization for authorization and approval of these substitutions prior to the manufacturing of this component. When there is no listed replacement the contractor shall request and recommend a substitute document from the proper A- 10 engineering organization by contacting the government contracting official.

4. Use of Northrop Grumman specification Z-R701 in conjunction with MIL-STD-130 is mandatory to ensure the proper marking of the parts. (Z-R701 has unlimited data rights in JEDMICS)

5. "IUID" (Item Unique Identifier) is required IAW MIL-STD-130. Specific instructions for marking methods, location, content and format shall be specified by the Contractor and submitted to the Government for approval prior to contract delivery. IUID is required for items where the individual cost per unit is greater than $5,000 or if the item has been identified as fatigue critical regardless of the items per unit cost.

6. Use of any process or manufacturing technique which creates a net edge on a metallic part by relying on heat at or above the parts melting point to produce the cut is not generally authorized (i.e.

laser cutting, electrical discharge machine (EDM), plasma cutting, etc.) without prior A-10 system program office approval. Likewise, other non-heat generating cutting processes involving high pressure fluids and slurries (i.e., water jet) are also not currently approved for use in the production of A-10 parts. Only those processes controlled by A-10 approved program specifications and A-10 drawings are permitted to be used in the manufacture of A-10 parts and assemblies.

7. Heat Treatment of Wrought Aluminum: Utilize SAE AMS 2770 for heat treatment of wrought aluminum alloy in lieu of SAE AMS-H-6088.

8. The contractor should work through the government procuring agency to contact the proper A-10 engineering organization in order to make sure any newly developed tooling and fixtures will produce an acceptable part that will fit on the aircraft. This will make sure changes and checks are done early to prevent failure of the first article.

9. Use of solid rivets (MS20426AD-5-2) is permitted as a suitable substitute to NAS1769MW-5-2 blind rivets.

10. Leave off the holes and nut plates on the doubler flange. Attach all necessary hardware in separate bag for delivery.

11. On Sheet 3 zone 5D of Drawing 160D511108, omit “.253” - .257” DIA hole 8 places to match underlying structure.”

12. Due to conflict in Sheets 5 A3, A5, A8, and 3 B3, B4, B5 in Drawing 160D511108, install the ribs as described in sheets 3 B3, B4, B5 which shows the ribs inclined at angles.

13. The use of either 1581 or 7781 Type Glass is approved as a substitute for 181 Type Glass.
