Marine F-35s grounded due to software concerns

WASHINGTON – F-35B joint strike fighters based at Yuma Air Station in
Arizona have been temporarily grounded due to issues with a key support
system.
The issue centers on the stealth jet's Autonomic Logistics Information
System, or ALIS, The software behind ALIS is woven through the F-35, and
plays a vital role in everything from planning missions to maintenance. In
April, ALIS 2.0.2 was installed on F-35A models and Navy F-35C models, but
was delayed in getting out to the F-35B jump-jet variants.
"Maj. Gen. Mark Wise, commanding general of 3rd Marine Aircraft Wing, made
the decision to temporarily suspend VMFA-211 flight operations pending fixes
to a recent ALIS software upgrade within version 2.0.2 that has presented
some anomalies," Maj. Kurt Stahl, director of public affairs with the 3rd
Marine Aircraft Wing, wrote in a statement. "There is nothing wrong with the
performance or safety of the aircraft itself, but it is imperative that we
ensure the ground-based ALIS system is working properly before flight
operations continue.
Stahl said that the F-35 Joint Program Office and prime contractor Lockheed
Martin have dispatched engineers to help resolve these issues associated
with the update, and said the issues center around "maintenance codes not
being reflected properly in the system." News of the grounding was first
reported by Inside the Navy.
Critics of the F-35 will likely seize on the software issue as more proof
that the famously delayed jet is of faulty design. The grounding comes just
days after the U.S. Air Force began flying operations after a ground stop
due for F-35A models at Luke Air Force Base. Those jets were grounded from
June 9-21 due to concerns about hypoxia among pilots. Since 2011, there have
been 15 related hypoxia incidents for F-35A models – five of which
occurred in the last month, leading to the recent grounding. |
