Lt. Gen. Jim Kowalski, commander of Air Force Global Strike Command, said the failed test did not put the safety of the nuclear arsenal at risk.
The failed inspection comes after 17 officers were stripped in May of their responsibilities to control nuclear missiles at Minot Air Base in North Dakota.
The 341st Missile Wing operates 150 Minuteman III ICBMs. The unit also failed inspections in 2008 and 2010, according to the Air Force Times.
