Boeing wanauza zaidi ya Airbus worldwide.. Na Boeing. Ndio ndege bora
Last year china ilienda kununua ndege zA boing kama 200.
wanalingana na Airbus muwe mna-back up claims zenu na si kuongea kishabiki! BTW dreamliner 787-8 nyingi zilirudishwa kiwandani kufanyiwa marekebisho umeme! Sasa huo ubora unaoongelea ni upi?

Logistical challenge – Once the fix was approved by the FAA, Boeing began to prepare then ship the battery containment kit for shipping to its 787 customers. "The parts easily go into a lower cargo hold but the tools and logistics to do the work probably are more suitable for a freighter," managing director of AOG James Testin says. "The equipment weighs close to 28,000 to 30,000 lbs (12.7 to 13.6 tons)."

The battery fix – A January 2013 battery fire prompted the worldwide grounding of all Boeing 787 Dreamliners -- one of the most advanced, sophisticated airliners in the sky.

To implement the fix, Boeing moved a small army of technicians to 13 international locations. Click through the photos to see how Boeing re-engineered the battery to make it safer.

Testing at HQ – Before Boeing could implement the battery fix for Dreamliner customers, it constructed mockups and carried out tests on aircraft at headquarters. Here, 787 flight line mechanic Steve Foster slots a new battery containment box into position in a 787 electronic equipment bay.

(CNN)The headaches for
Boeing over its 787 Dreamlinercontinue.
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
Dreamlinerwould 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.
Dreamliner returns to the sky – Lithium-ion batteries that overheated on two Dreamliners in January prompted authorities to ground all 50 of the 787s worldwide, but a redesigned battery system has cleared the way for the plane's return.

Those cases prompted the grounding of Boeing's global 787 fleet, with the
FAA announcing in January 2013 that "before further flight, operators ... must demonstrate ... that the batteries are safe and in compliance."
By April of that year, the
FAA cleared Boeing to make fixes to its battery system, paving the way for the aircraft to resume flying.
Still, problems persisted. This includes reports in January 2014 of smoke on a Dreamliner at Tokyo's Narita International Airport -- an incident Boeing said then "appears to have involved the venting of a single battery cell."
The
National Transportation Safety Board issued a report 11 months later blaming the battery problem on the overheating from an electrical short circuit that may have been caused by manufacturing defects and allegedly unsatisfactory oversight of the manufacturing process by both the FAA and Boeing.

The Japanese incident and the Boston fire prompted a worldwide grounding of the entire Dreamliner fleet -- which numbered 50 aircraft at the time.
