Airman 1st Class Martin Bauermeister, 362nd Training Squadron F-16 crew chief apprentice course student, performs a "safe for maintenance" inspection. The inspection includes making sure all pins are installed and the aircraft is statically grounded. Without statically grounding the aircraft, fuel vapors could potentially be ignited by static electricity. The inspection is performed every time before an aircraft undergoes any maintenance.
