No Easy Task:

The Air Force Research Lab has been working with the Warner Robins Air Logistics Center to perform non-destructive analysis of components from a C-5A to determine whether the giant airlifters are meeting life-expectancy predictions and whether it’s advisable to modernize these older airframes. AFRL scientists developed the process, turning over the actual evaluations of most components to various subcontractors—subject to AFRL independent audits. AFRL scientists are evaluating high-priority components—such as the inboard engine pylon attachment fitting and aft pressure bulkhead—and will tackle any components requiring “more thorough analysis.” The Air Force is under the gun from Pentagon officials and lawmakers to determine whether it makes monetary sense to revamp the C-5As as part of the overall C-5 modernization plan.
