Boeings Dreamliner under Fire

News came late yesterday that the second prototype of the B787, ZA002, landed with a cabin full of smoke in Laredo, Texas. The aircraft was en route to Harlingen, TX for trials of the nitrogen generation system. The fire broke out in the aft electronics equipment bay, the PFD and the auto throttle failed and the ram air turbine deplyed to provide enough electricity to handle th aircraft and to land it safely.
No one was injured, all test personell exited the aircraft via emergency slides.

The 787 saga of problems continues! All what can go wrong - goes wrong! Said someone "Murphy...?

What and if this latest part of the 787 saga means something really serious for the further flight test campaign and first deliveries of the aircraft remains to be seen.
In the best case there "just" was something like a short-circuit in the test equipment. Then the fire has nothing to do with the aircraft itself and the test fleet will be back in the air soon.
But it would be a lot worse if the fire has something to do with the electrical or electronical system of the aircraft.
  • If it is the electrical system and some kind of short-circuit, the problem would be to find to exact location and cause of the problem. Also it would have to be examined if the cause lies in the software that controls the electrics.
  • If it is the electronics itself where the fire started, it could either be a short-circuit on a circuit board or overheating of the electronics. How long then changes will take, is up in the air...and so long the aircraft won't....
In every case, the alarm bells in Rockford, Ill., where the Electrical Systems Division of Hamilton Sundstrand is located, are ringing!
