Boeing sees 787 battery fixes done by mid-May

Boeing voiced confidence Wednesday that all Boeing 787 Dreamliner aircraft, grounded worldwide for overheated lithium-ion batteries, will have had a company fix installed by mid-May.

"We have pretty big confidence we can be done with this in a few weeks, by mid-May," Jim McNerney, Boeing chairman, president and chief executive, said in a conference call after the company reported first-quarter earnings.
