Memorandum for Vendors/Contractors – Unmarked Engineering Data

This is a memorandum issued by the Air Force Life Cycle Management Center at Hill Air Force Base on February 2, 2022, addressing the handling of unmarked engineering drawings and technical data in contract deliverables. The memorandum directs vendors and contractors that any drawings not marked with distribution statements and export control notices must be treated as bearing a Distribution D marking, which restricts distribution to Department of Defense and U.S. DoD contractors only, classified as Critical Technology.

The memorandum includes instructions and warnings regarding export-controlled technical data, emphasizing that unauthorized dissemination is prohibited and violations of export laws—including the Arms Export Control Act and Export Administration Regulation—carry severe criminal penalties up to two years imprisonment, fines of $100,000 or more, and potential disqualification from future DoD contracts. The attachment provides comprehensive guidance on controlling export-controlled technical data, including liability disclaimers stating that the U.S. Government assumes no liability for patent infringement, data accuracy, or losses resulting from use of the technical data.
