Meanwhile, small holes drilled into the bottom of the case that encloses the cells and battery management unit allows moisture to drain away from the battery. This means that regulators in the Americas, Europe, Asia, Africa and the Middle East agree that the 787 battery system changes and validation of those changes meet safety requirements and that airlines around the world can now resume 787 flights. It also installed electrical and thermal insulation above, below and between each cell to prevent heat migration. Within the battery itself, Boeing engineers wrapped an electrical insulator between each of the eight cells to isolate them from each other and prevent propagation. Engineers have also devised a way to “soften” the charging cycle in a way to put less stress on the battery. The battery problem that last year afflicted Boeings worldwide fleet of 787 Dreamliners appears to have recurred. The so-called fix includes a modification to the charger and battery monitoring unit designed to narrow the acceptable level of charge–in essence, lowering the maximum charge allowed and raising the minimum level of discharge allowed. After Boeings fleet of Dreamliner 787s was grounded for more than eight weeks, its makers believe it should be back to carrying passengers within weeks. Federal Aviation Administration completes its evaluation of the testing data.

Painted in LOT Polish Airlines livery, LN 86 took off from Paine Field in Everett, Washington, at 10:39 a.m. Boeing took a charge of 3.5 billion to cover additional delays in delivering copies of its 787 Dreamliner jet. Boeing took a significant step toward returning the 787 to service on Friday, when it flew Dreamliner Line Number 86 on a one-hour, 49-minute mission to demonstrate conformity of its battery system modification to U.S.
