A foreign body may have triggered the fire that broke out Nov. 9 on a test flight of a Boeing 787, forcing since the American manufacturer to suspend his campaign test flight within 3 months delivery date official said Monday The Tribune.
"A tool, forgotten in a cabinet (which is software components, ie), has caused a short circuit," according to comments from industry sources reported by the daily La Tribune.
However, this would not have such consequences, notes the newspaper, noting that the entire power distribution system is at stake.

And translation of the La Tribune article:
Incredible as it may seem, it is a forgotten tool in a cabinet that is at the origin of the fire on 9 November that forced Boeing to halt flight testing of the B787. Although detected, the anomaly still poses problems for engineers who need to understand how to prevent it from reproducing. Among the subcontractors in the crosshairs: French Zodiac.ZA004 did make the ferry flight to Everett yesterday though ZA003 has not returned to Boeing Field as of yet but Guy Norris is reporting that ZA002 being prepped for a return flight back to Boeing Field though no date has been set. Additionally, ZA001 is now entering a lay up period for maintenance with ZA004.
FOD for "foreign object damage" or damage caused by foreign body.

"A tool, forgotten in a cabinet (which is software, components ..., ed) caused a short circuit," says Will we at The Tribune.
However, this should not have such consequences. Because the whole system of power distribution, a crucial point in the plane, which is involved. "For security, everything is redundant in a plane. But the blackout that occurred in the first cabinet spread to the second, and the aircraft had to use emergency power management to ask, "say the sources. This is a small wind turbine (called the rate) that is located on the fuselage and a small generator supplying emergency power for the aircraft to land.
Several manufacturers are involved in this can of worms. Including French Zodiac one of the subcontractors of the American Hamilton (subsidiary of United Technologies), supervisor of distribution of electricity in the air, and of course Boeing, Specifications and controls. The French equipment provides such components in the cabinet. Hamilton provides other. "However, you can not blame anyone for now, says one industry, as more than a problem of quality of play is a problem in the logic of management of the electrical system since the breakdown spread. "
Nevertheless, the results of races may be final. The Boeing 787 was headed straight for seventh behind. It is even a certainty for the highly respected Steven Udvar-Hazy, head of aircraft lessor Air Lease Corporation. "If changes are needed on some software, it will take time and aircraft deliveries will be postponed," said a French industrialist. Morgan Stanley, such a scenario could shift the first deliveries of the aircraft at 2012. They were laid in 2008, when launching the program in 2004.
