F-35 Fuel Pump Software Issue Resolved, Flight Tests Resume

STOVL Door Hinges Still Under Review

Two of Lockheed Martin's F-35 JSF test aircraft are flying again after a software glitch controlling the airplanes' fuel pumps was resolved. An LMC spokesman said in an e-mail Tuesday that the software upgrade had been loaded onto the flight test aircraft, and that two had been cleared for flight.

The airplanes had been grounded since October 1st over the software glitch, which could have caused all three fuel boost pumps to fail on the airplane, resulting in an engine stall.

Multiple media sources including Bloomberg News report that Pentagon spokesman Geoff Morrell said in a news conference that the issue was not a "serious setback." He said flight test programs are designed to uncover just such anomalies and fix them before production.

However, an aviation blog from the Fort Worth Star-Telegram indicates that the planes are flying only in conventional mode, as an issue with the auxiliary air intake door hinges on the STOVL variant has yet to be addressed.
