Boeing sticks to production plans, battery for 787

Boeing CEO Jim McNerney says the company is sticking with plans to speed up production of its 787 and sees no reason to drop the troubled lithium-ion batteries at the center of the plane's problems.

A fire and emergency landing earlier this month, both involving the batteries, prompted regulators to ground Boeing's newest and highest-profile plane.

All Nippon Airways said Wednesday that it replaced batteries 10 times before the overheating problems surfaced earlier this month. McNerney says airlines have been replacing 787 batteries at a rate that's "slightly higher" than Boeing had expected. They've all been replaced for maintenance reasons, not for safety concerns, he said on a conference call.

Boeing says about 2,000 batteries of all types are replaced every year on its various planes.

U.S. aviation officials have asked Boeing for a full operating history of the batteries on the 787s.

McNerney says "good progress" is being made in finding the cause of the problems. But he didn't have a timeline for when the plane would get back in the air.
