All F-35 aircraft were temporarily grounded Thursday following the crash of one of its jump-jet variants in late September in South Carolina, according to a U.S. military statement.

Flight personnel were ordered to inspect a fuel tube inside each F-35’s engine, pull out bad ones, and return aircraft with known good tubes to flight status. Inspections on the Pratt & Whitney engines are expected to be completed within the next 48 hours, the F-35 Joint Program Office said Thursday morning.
