What Rockford Defense Buyers Should Know
Collins Aerospace quality systems reject incomplete documentation
Missing material certs or process certifications hold shipments at Collins receiving. Ship complete cert packages with every delivery.
Avionics enclosures need EMI/RFI shielding specs on the drawing
Collins cockpit display and communication system housings require specific shielding call-outs. Specify MIL-STD-461 compliance requirements.
AS9100 registration is baseline for Rockford defense work
Every major Collins Aerospace program requires AS9100 suppliers. Confirm registration before responding to any RFQ.
