Brian McKinley, left, and Airman 1st Class Colton Bair, 35th Maintenance Squadron Aerospace Ground Equipment members, relocate a generator after cleaning it as part of a phase-two periodic inspection at Misawa Air Base, Japan, Aug. 8, 2013. Phase-one inspections are done every six months, and include changing air filters, changing oil and replacing wheel bearings. The phase-two periodic inspections are done every 12 months, and are more complicated and in-depth than phase-one inspections. (U.S. Air Force photo by Airman 1st Class Kaleb Snay)
