The Joint Surveillance Target Attack Radar System E-8C is the only aircraft in the Air Force inventory currently testing the new large prototype composite chocks. Va. Sink said the new chocks are expected to last five to 10 times longer than traditional wooden chocks.
Wooden chocks become water logged from rain and snow, and begin deteriorating.
The average chocks only last nine to 18 months and have to be painted frequently to maintain appearance and keep them from deteriorating even faster. The new chocks are projected to save the Air Force money since they last longer, don't need to be painted and aren't a potential foreign object damage, or FOD, problem for the aircraft engine.
