Lockheed Martin Potentially Mixed Up Structural Fasteners in Most F-35s
From the Air Force Magazine website
Hundreds of F-35s could have the wrong fasteners in “critical areas,” according to the Defense Contract Management Agency. But F-35 builder Lockheed Martin says the problem may not need to be fixed.
“All aircraft produced prior to discovery of this [problem] have titanium fasteners incorrectly installed in locations where the design calls for Inconel,” the F-35 Joint Program Office said in an email in response to a query from Air Force Magazine. “Because of this, the engineering safety analysis of the issue has assumed that each critical F-35 joint was assembled with the incorrect fasteners.”
