Dreamliner crisis: Boeing seeks test flight for 787

[mhm]

Boeing has sought the permission of the US Federal Aviation Administration (FAA) to conduct test flights of its 787 Dreamliner passenger plane.

All 50 of Boeing's 787s were grounded last month because of an ongoing investigation into battery problems.

A battery on a Japan Airlines 787 caught fire, and a malfunction forced an All Nippon Airways flight to make an emergency landing.

Some analysts said this suggests Boeing may be closer to resolving the issue.

We've covered the Boeing Dreamliner lithium-ion problems before, but New Scientist has taken an in-depth look at the battery trouble.

The batteries store twice the power of nickel-cadmium cells, making them much lighter - writes Paul Marks - but they are known to carry a fire risk under certain operating conditions.

Quote "Striking a note of caution , he says that no one yet knows if the batteries themselves (built by GS Yuasa of Japan and packaged by Thales of France) were at fault or if it was an issue with the electronics, they plug into...."

So why write about it if you have nothing further to add Mr Marks?

For the record, in 35 years in aviation I've seen all types of aircraft batteries overheat or boil and a few catch fire.
