Air Force Times Mobile - F-35B grounded following fueldraulic failure

The office made the decision after a
10 :00 a . m . CST test flight at Eglin was
aborted by the pilot during a
conventional takeoff roll. There were no
injuries to the pilot or the crew .
The abort occurred because of a failure
to a propulsion fueldraulic line, which
enables movement in the actuators for
the STOVL' s exhaust system .
The F - 35 A ( conventional ) and F - 35 C
( carrier ) variants are unaffected.
" Implementing a precautionary
suspension of flight operations is a
prudent response until F - 35 B
engineering , technical and system safety
teams fully understand the cause of the
failure , " wrote JPO spokesman Joe
DellaVedova in an emailed statement.
