A bolt inspection tool invented by an Air Force technical sergeant has won a U.K. base’s Innovation of the Quarter Award. Tech. Sgt. Steven Iziguerra, 100th Maintenance Squadron Non-Destructive Inspections Section noncommissioned officer in charge, won the award for RAF Mildenhall for a slot guided inspection carriage he developed to increase the efficiency of the bolt inspection process, according to a recent news release. The tool was made from plastic and 3D printed, and enables airmen to inspect 24 bolts at a time, compared with seven previously, meaning a 93 percent reduction in inspection time. The invention is already saving more than $25,000 per year. Read more at AF.mil.
