Lockheed Martin Corp. halted deliveries of its F-35 jets to the U.S. Air Force for much of this month because of a flaw in a system used to prevent explosions if fuel tanks are hit.
Flaws in tubing used to circulate inert gas into fuel tanks to prevent explosions were found in 14 of 24 Air Force models of the fighter jet inspected, the Pentagon's F-35 program office said in a previously undisclosed June 5 memo to congressional staff.
But Lockheed said Wednesday that it resumed deliveries, with two of the fighter jets provided on Tuesday. It recommended that flights be restricted "within 25 miles of lightning or thunderstorms" as a safety precaution while the contractor works with the Defense Department's F-35 program office on a corrective plan.
惟該集團週三表示，週二交付了2架戰機，業已恢復交付作業，並建議該型戰機均不得飛駛入距閃電或雷雨 25 英里的範圍之內，以維安全，而該型戰機承商同時亦與國防部 F-35聯合專案辦公室共同研議修正計畫。
