The Federal Aviation Administration is undertaking a comprehensive review of the critical systems of Boeing's 787s, the aircraft maker's newest and most technologically advanced plane, after a fire and a fuel leak earlier this week, the agency said today.

Two Decatur manufacturers, Hexcel Corp. and Toray Carbon Fibers, are major suppliers of materials used in the 787. Hexcel is in the midst of an expansion to increase capacity.

The FAA review will include the design, manufacture and assembly of those systems, the FAA said in a statement. Officials plan to detail the review at a news conference Friday morning.

The 787, which Boeing calls the "Dreamliner," relies more than any other modern airliner on electrical signals to help power nearly everything the plane does. It's also the first Boeing plane to use rechargeable lithium ion batteries, which charge faster and can be molded to space-saving shapes compared to other airplane batteries. The plane is made with lightweight composite materials instead of aluminum.

A Boeing official said the company is working with the FAA. The FAA statement gave no indication that the agency intends to limit or prohibit the 787 from flying during the review.
