Boeing says it will also begin installing the changes on new airplanes at the company's two 787 final-assembly plants, with deliveries expected to resume in the weeks ahead. Despite the disruption in deliveries that began in January, Boeing says it expects to complete all planned 2013 deliveries by the end of the year. Boeing further expects that the 787 battery issue will have no significant impact to its 2013 financial guidance, the company says.
