FAA orders new 787 electrical fix to prevent power failure
All Boeing 787 operators will be required to periodically deactivate the electrical system to avoid a problem with a newly-discovered software bug that could cause the aircraft to lose alternating current (AC) power, the US Federal Aviation Administration says in a new airworthiness directive. The agency adopted the final rule after Boeing reported the results of a laboratory test showing a total loss of power is possible if the generator control units run continuously for eight months, says the… (www.flightglobal.com) Más...Sort type: [Top] [Newest]
Please, someone provide an example of any aircraft that has ever been run continuously for 284 days? Anyone? That is the AC generators mounted on the engines cited in the AD that have to run continuously and has occurred only under lab conditions at Boeing. This is another example of sensationalism on the part of the FAA and the news media. And BTW, losing the AC generators on the 787 will not cause 'loss of control' when there is hard wired DC bus power from the battery system and the Ram Air Turbine (RAT) that will automatically deploy as the last resort to provide power to primary systems. So no, the 787 will not fall out of the sky with this rediculous scenario defined by the FAA.
But but but that's beside the point you are missing the sensational
headlines that make news print!!!!!!!!!!!!!! LOL. You are so right
thanks for the post.

This is why all planes should have mechanical backup. If the computers fail, there needs to be a backup system.
That is the reason that I do not like airbus and it's computer system... It is a bad enough to have fly by wire, but having a computer between the stick and the flight control is too much.
I agree am on a homebuilt web site and those building new ones have all of the
great stuff and latest but not one steam gauge that could save ones life if the battery
fell out of it, I know its extreme but get the drift. Also when looking at those
screens seems would take more time than a scan of needles from steam gauges. Don't
have any time in the new ones or have flown in many years either.

Updated: FAA finds Boeing Dreamliner could lose all power, issues maintenance mandate
The Federal Aviation Administration on Friday issued a directive mandating "a repetitive maintenance task" for that model of airliner due to issues with its power supply. Specifically, the FAA explained testing revealed that 787s could lose all AC electrical power after being continuously powered for 248 days, a problem that, if left unchecked, would leave an aircrew unable to control the plane.
