(NEW YORK) — The Federal Aviation Administration decided to halt U.S. flights on Boeing’s new 787 Dreamliners to investigate problems with the jets’ batteries. Now, some are asking why the FAA didn’t pay closer attention before the planes went into service.
The Wall Street Journal reports that when the FAA approved the Dreamliners’ lithium-ion battery systems — which had never been used before in big jets — the agency “relied extensively” on data from Boeing, the planes’ manufacturer.
Boeing’s information suggested that the batteries had “redundant safeguards,” making them “essentially foolproof.”
The FAA doesn’t have the budget or staff to do its own testing but says it provided “rigorous oversight” during the certification process.
After two major battery malfunctions, that process itself is coming under scrutiny.
