FIXING THE 787: Boeing says it has installed its new battery system on 10 787s out of 50 that have been delivered to airlines.

FINANCIAL IMPACT: Boeing Co. reported a profitable first quarter despite the 787 problems, although revenue shrank in part because of the grounding.

WHAT'S NEXT: Boeing says it expects to resume delivering 787s in early May, which would be nearly four months after they were grounded because of smoldering batteries.
