ORLANDO, Fla. — The Pentagon has suspended all test flights for the entire Lockheed Martin F-35 Joint Strike Fighter fleet due to engine problems.

The move came nine days after the Pentagon cleared the F-35B jump-jet variant, designed for the U.S. Marines, to resume tests after a monthlong suspension. Both suspensions are due to problems with the engines. It also comes at a time when the program is facing increased scrutiny from lawmakers and senior DoD officials.

Unlike the last suspension, which was only for the B variant, this suspension affects all three variants: the F-35A Air Force conventional takeoff version, the F35-B for the Marines, and the F35-C carrier variant for the Navy.

“On Feb. 19, 2013, a routine engine inspection revealed a crack on a low pressure turbine blade of an F135 engine installed in a [conventional takeoff] test aircraft at Edwards Air Force Base, Calif,” wrote Kyra Hawn, Joint Program Office (JPO) spokeswoman, in a statement.
