An Airman from the 19th Aircraft Maintenance Squadron rinses the tail wing of a C-130J Hercules Jan. 23, 2014, at Little Rock Air Force Base, Ark. Dirt, grease, grime, exhaust carbon and hydraulic oils can hide cracks or other faults on an aircraft and must be washed before an isochronal inspection.
