"In order to tackle the issue, Colorado Air National Guard maintainers of the 140th Maintenance Group has implemented new maintenance practices, led by U.S. Air Force Staff Sgt. Danielle M. Morgan and Tech. Sgt. Taylar M. Reilly, that have allowed the team to complete, locally, repairs on two aircraft experiencing the issue at the same time, that would normally be done at a depot facility, with an extended downtime of the jets."
So the fault is fixable and being repaired, albeit very slowly.
