According to reports, a team led by Boeing Commercial Airplanes President Ray Conner is scheduled to meet the US Federal Aviation Administration (FAA) in Washington on Friday, to seek the regulators' approval for redesigned 787 Dreamliner batteries.

On Wednesday, Boeing instructed some of its top-notch technicians at its Auburn parts-manufacturing facility to start building new, super-sturdy containment boxes for the lithium-ion batteries on its 787 Dreamliners; a move which is part of the company's redesign aimed at getting the planes to fly again by April.

According to the information shared by `inside' sources on the condition of anonymity, the redesign plan being worked out by Boring includes insulation made of heat-resistant glass around the cells of the lithium-ion battery used on the Dreamliners.

While Conner and his team will put forth Boeing's 787 battery-fix plan to the FAA officials - including Administrator Michael Huerta - on Friday to get the battery repairs approved by the agency, it is not yet clear whether the regulators will give their go-ahead to the fast-paced April schedule being planned by the company, till tests ensure the safety of the battery fix.

Meanwhile, with there being some apprehensions with regard to the permanence of battery redesign worked out by Boeing, a congressional aide revealed that Boeing representatives were, at a recent meeting, "adamant that it will be a permanent fix, and rejected reports that mentioned a temporary fix."
