USMC MV-22 Flightline Qualification CDI Patch — MV-22 Osprey Collateral Duty Inspector Glow-in-the-Dark PVC Patch CDI qualified — the inspector who ensures every Osprey is mission-ready. The Collateral Duty Inspector (CDI) qualification is one of the highest maintenance certifications a Marine can achieve on the MV-22 Osprey flight line. CDI-qualified Marines are authorized to perform final inspections on critical and major maintenance actions, serving as the last line of quality assurance before an aircraft is returned to service. The CDI's signature carries tremendous weight — it certifies that a maintenance action was performed correctly, all technical procedures were followed, and the aircraft is safe for continued operations. This glow-in-the-dark PVC patch identifies CDI-qualified MV-22 maintainers during nighttime flight line operations. Earning the CDI qualification requires years of maintenance experience, comprehensive knowledge of the MV-22 airframe and its systems, and demonstrated reliability and attention to detail. CDIs work alongside Plane Captains, Safe For Flight qualifiers, and CDQARs to form the quality assurance chain that keeps Marine tiltrotor aircraft safe and operational. The durable PVC construction withstands the rigors of daily flight line use, while the GITD feature ensures visibility during the nighttime operations that are routine in Marine aviation. Perfect For: MV-22 CDI-qualified maintainers, Marine aviation inspection professionals, Osprey flight line supervisors, maintenance qualification patch collectors, GITD PVC patch fans, and anyone who respects the inspectors who keep the Osprey fleet airworthy. CDI inspected — cleared for flight.
