WASHINGTON (AP) — Boeing has developed a plan that it intends to propose to federal regulators to temporarily fix problems with the 787 Dreamliner’s batteries that have kept the planes on the ground for more than a month, a congressional official told The Associated Press on Wednesday.

Boeing Commercial Airplanes CEO Ray Conner is expected to present the plan to Michael Huerta, head of the Federal Aviation Administration, in a meeting on Friday, the official said. The official spoke on condition of anonymity because he wasn’t authorized to speak publicly.
