FAA approves Dreamliner battery redesign
March 14 , 2013
The U.S. airline regulator on Wednesday approved a plan to redesign the lithium-ion batteries of the Boeing 787 Dreamliner.
However, the Federal Aviation Administration (FAA) gave no indication as to when the planes will be allowed to carry passengers again.
All 50 Dreamliners in operation were grounded after the batteries emitted smoke on numerous separate occasions.
The plane is the first in the world to use the lithium-ion batteries, which are lighter, more powerful and recharge more quickly.
The FAA has also approved limited test flights for two aircraft to test the batteries.
Boeing delivered 46 Dreamliners to customers in 2012 but a series of events in January raised doubts over its safety.
Problems occurred on several planes owned by Japanese airlines; one plane had a cracked cockpit window, another had a fuel leak and a third plane was forced to make an emergency landing after a smoke alarm went off.
As a result, Japanese carrier ANA lost some $15 million in revenue.
