BARKSDALE AIR FORCE BASE, La. — The Air Force Global Strike Command completed an accident investigation board following a May 2014 mishap during maintenance on an intercontinental ballistic missile.
On May 16, 2014, at approximately 11:15 p.m. MDT, a Minuteman III ICBM assigned to the 90th Missile Wing at F.E. Warren Air Force Base, Wyoming, became nonoperational during a diagnostic test. While maintenance personnel were troubleshooting the issue, a mishap occurred that resulted in approximately $1.8 million of damage to the missile.
The incident did not result in any injuries, prevent the Air Force from meeting its ICBM requirements, or pose a hazard to public safety.
The Accident Investigation Board found that although the maintenance team chief was properly trained for the task he was performing, he mistakenly performed an action not directed by the technical guidance.
Accordingly, the team chief and the two Airmen on his team were decertified, retrained and returned to duty.
To prevent a reoccurrence of this mishap, the Air Force has strengthened technical guidance, modified training curriculum, and shared information with the other missile wings regarding the conditions that led to the mishap.
In accordance with Air Force policy, further details related to this mishap and its associated investigation are classified.
