TECHNICAL ISSUES: Japanese authorities identified the causes of fuel leaks and other problems with Boeing's 787 but are still investigating the more serious battery problem that forced an emergency landing in January and the worldwide grounding of the jets.

CLOSER TO HOME: Congressional officials say Boeing is proposing a long-term fix for the 787 batteries that won't have the planes back in the air until April at the earliest. The officials say the plan will require some testing and safety recertification of the plane's lithium ion batteries, but not a complete recertification.

GROUNDED: All 50 of the 787 jets in service around the world have been grounded for more than a month after a lithium-ion battery in a 787 operated by All Nippon Airways overheated Jan. 16, forcing an emergency landing in western Japan. Earlier in January, a lithium-ion battery caught fire in a Japan Airlines 787 parked in Boston.
