- Boeing says airlines have done what they need to do and have a "go-forward plan"
- The FAA orders "a repetitive maintenance task" on Boeing 787 Dreamliners due to issue
- The Dreamliner has been plagued by battery problems; its fleet was grounded in part of 2013
(CNN)The headaches for Boeing over its 787 Dreamliner continue.
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.
The order took effect immediately, with the federal agency finding that there's no good reason to delay the decision.
"The FAA has found that the risk to the flying public justifies waiving notice and comment," the agency said.
The maintenance mandate was characterized as temporary, until software is developed to resolve the problem.
A Boeing spokesman said its customers learned about this issue and what they need to do to fix it about two weeks before the FAA's announcement. In fact, "all operators have already completed the off-cycle on fix," said spokesman Doug Alder Jr.
"All of the airlines have completed the steps they need to take at the moment," Alder added, "and they have a go-forward plan."
This marks the latest setback for Boeing over its 787, which debuted in 2011 in Asia and a year later in the United States amid much fanfare. The American manufacturer has boasted that the Dreamliner would save airlines money on fuel because its body consists of lightweight composite materials. Besides its larger size, the new aircraft also featured passenger comforts such as bigger windows, larger overhead bins and better ventilation.
Yet the Dreamliner's development was marred by production delays and other problems. And there were more issues once the fleet rolled out, including two instances of overheating batteries on a Japan Airlines plane in Boston and an All Nippon Airways jet in Japan.
