Airman 1st Class Robert Dumbeck (left), 9th Maintenance Squadron aircrew egress systems journeyman, and Tech. Sgt. Cody Clark 9th MXS aircrew egress systems craftsman, inspect an egress seat D-ring before installing a D-ring guard, Jan. 16, 2020 at Beale Air Force Base, California. When a pilot pulls the D-ring, it fires an initiator that sends gas pressure to explosives. Each of these explosives fire at different items like the lap belt, inertia reel, and foot retractors.
