Honduran air force members glean valuable knowledge from NDI technicians
U.S. Air Force Staff Sgt. Ian Douglas, 355th Equipment Maintenance Squadron nondestructive inspections lab journeyman, teaches members of the Honduran Air Force how to conduct ultrasonic testing during a subject matter expert exchange event on Davis-Monthan AFB, Ariz., Aug. 19, 2015. Ultrasonic Testing uses ultrasonic vibrations to detect internal defects, delaminations, disbonds, and discontinuities. The five members from the Honduran Air Force teamed up with 12th Air Force (Air Forces Southern) and the 355th EMS for a subject matter expert exchange that focused on a variety of nondestructive inspections lab processes and maintenance safety standards.
