Airman Philip Liggins uses a magnetic coil to inspect an engine mount fuse pin at Royal Air Force Base Mildenhall, England, on Tuesday, June 20. Magnetic particle fluid is poured over aircraft parts; when it seeps into the cracks, it helps detect cracks and defects. Airman Liggins is a non-destructive inspection specialist with the 100th Maintenance Squadron.
