Model maker Chris McCoy, right, demonstrates to machinist apprentice Collin Grummert how to use a FaroArm coordinate measuring machine to verify the dimensions of a 522 fitting for an H-53 heavy-left helicopter. McCoy leads the machining of the component for the Fleet Readiness Center East manufacturing department, which produced the fitting to fill gaps in the H-53 supply system and bring an aircraft out of work stoppage. Work is under way on a second fitting.  (Photo by Heather Wilburn, Fleet Readiness Center East Public Affairs)
