Boeing planning software fix for 787 electrical issue

NORTH CHARLESTON, SC (WCSC) - Boeing is working on a software update to fix a potential electrical issue with its Dreamliner that could cause the 787 to lose power.

The company says the problem showed up in the lab, and the company notified customers 13 days ago. 

Friday, the Federal Aviation Administration issued a directive that all Dreamliner operators complete a fix which involves a power-off, power-on cycle. 

The FAA says it took the action "to prevent loss of all AC electrical power, which could result in the loss of control of the airplane."

Boeing spokesman Doug Alder points out the directive addresses something that only happened in the lab after eight months of continuous power which would be highly unusual.   Boeing reports no airplane in the fleet had that happen.

“Simulated testing determined that this condition is possible in cases where an airplane's power is left on for more than eight months,” Alder said in an email.  He says operators will perform powering cycles on scheduled intervals until the software update, which is expected in the fourth quarter of this year.
