Airworthiness authorities for the Navy and the Air Force yesterday approved the F-35 Lightning II joint strike fighter fleet to resume limited flight, Pentagon Press Secretary Navy Rear Adm. John Kirby said.

In a statement issued this morning, Kirby said this is a limited flight clearance that includes an engine inspection regimen and restricted flights that will remain in effect until the root cause of a June 23 engine fire on the runway at Eglin Air Force Base, Florida, is identified and corrected.

The fleet was grounded July 3, putting in jeopardy a long-awaited appearance by the F-35 at the Farnborough International Airshow in England. In his statement, Kirby said officials remain hopeful that the F-35 can make an appearance at Farnborough.

โ€œThis information is an encouraging step, but no final decision has been made at this time,โ€ he said, noting that safety remains the overriding priority.
