The Challenge

Keeping a Legacy System in Service

A Canadian defence integrator required replacement mounting hardware for a legacy platform where the original source of supply was no longer available. The drawings carried complex GD&T callouts on mounting interfaces, and the program required controlled handling of technical data, material traceability, and a complete inspection documentation package.

Add any program timing or sustainment constraint.

Our Approach

Controlled Data, Controlled Production

Controlled Data

Technical drawings and engineering data were handled under FMW’s Controlled Goods Program registration and document controls.

Machining to GD&T

Components were machined to ASME Y14.5 on a 5-axis (4+1) machining center, holding critical interfaces in a single setup.

Inspection Package

Critical features were verified on the Hexagon CMM, with First Article Inspection to AS9102 and in-process and final inspection records.

Traceable Delivery

Material certifications, heat/lot traceability, and a Certificate of Conformance accompanied each shipment.

The Result

A Qualified Domestic Source of Supply

  • First Article accepted with no non-conformances
  • Delivered in X weeks from purchase order
  • Follow-on production or additional part numbers, if applicable
  • Complete inspection documentation package retained and archived

Optional customer quote, with approval.
