The F-35 program leadership has cleared some, but not all, F-35 test aircraft to resume flight operations after an in-flight anomaly with one aircraft last week temporarily suspended operations. F-35 spokesman Joe DellaVedova told the Daily Report Tuesday that three F-35As (AF-1, AF-2, AF-3) and four F-35Bs (BF-1, BF-2, BF-3, BF-4) are no longer under the flight suspension. In fact, AF-1 on Monday became the first F-35 test aircraft to return to flight. However, three test assets (AF-4, BF-5, CF-1) and the first two F-35 production-version airplanes (AF-6, AF-7) remain grounded, he said. The fleet-wide flight suspension went into effect as a safety precaution after AF-4 experienced a dual generator failure and oil leak during a March 9 flight at Edwards AFB, Calif. Program officials continue to investigate the root cause, but already have determined that the issue is unique to a newer generator configuration that first appeared in the later batch of test aircraft, said DellaVedova. Therefore, they rescinded the flight suspension on the earlier test aircraft, he said.
The Air Force and Boeing agreed to a nearly $2.4 billion contract for a new lot of KC-46 aerial tankers on Nov. 21. The deal, announced by the Pentagon, is for 15 new aircraft in Lot 11 at a cost of $2.389 billion—some $159 million per tail.
