Boeing 787: US-aviation authority warns against power failure in the Dreamliner

The US aviation safety authority warns: in Boeing's Dreamliner in flight can the event of a power outage, the aircraft uncontrollable. Guilt is a computer glitch.

The US Federal Aviation Administration (FAA) has a warning for the 787 Dreamliner Boeing-Langstreckenjet published. Thus, a software problem cause in the plane of the power fails, so that the pilots would lose control of the plane.

On Friday, the authority published a so-called Flugtauglichkeitsdirektive, in which it is said that it is by the aircraft manufacturer Boeing itself has been made aware of the problem. The error was detected in laboratory tests.

Obviously, this is a typical software problem, a bug in it. According to the warning "A software count in the control units of the power generators after 248 days continuous operation overflow, which causes the control units in a protected mode switching."

$85 Per restart

Boeing has in the meantime all operators informed of the 787. In a so-called Multi Operator message explains the procedure the Company the amount of electrical current, with the man on a Boeing 787 can be turned off, to restart the generators.

This process must be within seven days after the publication of the current Flugtauglichkeitsdirektive or 120 days after the first authorization of the aircraft will be carried out. The process must then be repeated every 120 days.

Even the cost to the operators of the currently 28 in the United States approved by the FAA Dreamlinern precisely. It therefore has the Generatoren-Neustart take approximately one hour per machine, the Authority with $85. In total, the American 787-operators so costs in the amount of 2380 dollars per restart.

Nerds mock Boeing

Compared with the problems that the Dreamliner Bahrain so far, should be the really limited sums. Clearly, the problems with possible serious crazing in the wings, of which approximately 40 machines were affected according to Boeing.

But it is above all a worldwide was dramatic, the grounding on the 787 was imposed after several times important lithium-ion batteries on board such aircraft had burned. In addition, it would have cracked windscreens and defective toilets the plane in the headlines.

The current warning the FAA, however, less for fear of the ultra-modern aircraft, in which the demand is so high, that Boeing's production halls no longer suffice.
