Boeing 787 Dreamliner Flight Cancelled After 'Brake Problems'

Third Dreamliner Flight Cancelled After 'Brake Problems'

A brake problem on a Boeing 787 Dreamliner has caused the cancellation of an All Nippon Airways flight in Japan, the third fault detected on the jet in as many days.

The domestic flight to Tokyo was grounded in Yamaguchi after a light in the cockpit showed that the brake parts needed replacing.

The Dreamliner has been beset by a series of troubling technical issues, despite being hailed as the most advanced jet ever made when it was launched in 2011.

Boeing shares fell 0.3% in premarket trading Wednesday after the latest incident, following a 2.6% fall on Tuesday after a fuel leak on a Japan airlines plane, according to CNN.

The flight from Boston's Logan airport to Tokyo was cancelled after engineers found around 40 gallons of fuel had been spilled. The 178 passengers and 11 cabin crew on board had to be evacuated and while the plane was towed back to the gate, the cockpit and cabin filled with smoke, reported Sky News.

According to a spokesperson for the airline the plane departed later that afternoon, despite the Dreamliner suffering what she termed a "mechanical issue."

Japan Airlines also had to contend with an electrical fire that broke out on an empty Dreamliner jet at Boston. No one was injured in the blaze which officials claimed was caused by a battery in the auxiliary power system exploding after it overheated. A mechanic inspecting the jet after passengers had disembarked discovered smoke and raised the alarm.

The Federal Aviation Administration and the National Transportation Safety Board are investigating the incident, reported the Guardian.

"Even though it happened on the ground, rest assured the FAA is asking, 'what if it happened in the air?'" Carter Leake, an analyst at BB&T Capital Markets in Virginia, told the BBC.

Last year a United Airlines flight made an emergency landing after an electrical problem.

In the 14 months the planes have been in operation, there have been two other incidents including a similar electrical problem and a manufacturing fault.
