And I still think it was a mistake to retire the F-14 and cut them up. Damn shame. Even if they just retired them from carrier service and left them as land based. If it wasn't required to land on a carrier, I bet even the AF guys could fly one ;)
They have identified the aircraft with the thinned longerons and have established shorter inspection intervals for those aircraft. They have developed a Depot level longeron replacement kit that will replace those thinned longerons as necessary during depot-level maintenance.
And they will phase out those aircraft with the highest number of flight hours a bit early.
Answer: All of the above.
