Boeing 787 Battery Design Flaw

The National Transportation Safety Board US (NTSB) attributed today the fire of the battery of a Boeing 787 in 2013 to a design fault of the device, so blamed Boeing error and the authorities have not detected.

According to a report by the NTSB released today, a short in one of the eight cells that make up the batteries of 787 was the overheated battery, spread to other cells and set fire to the apparatus the January 7, 2013.

The affected aircraft, Japan Japan Airlines, was at that time without passengers detained at the airport in Boston (Massachusetts), so no regret any hurt, but this incident with similar occurred during those dates led to the aviation authorities worldwide to suspend flights of Boeing 787 for three months.

The report by the NTSB determined that Boeing failed to anticipate during design and testing period of the battery to the possibility that an incident of this type occurs, and blamed the Federal Aviation Administration (FAA) had not detected this weakness.

Both Boeing and the FAA had certified that overheating of the battery cells could not be extended to the other, something did happen in that case.

The NTSB report also provided sixteen new recommendations for both aircraft manufacturers such as the FAA strengthen their controls and increase the requirements in certifying the safety of lithium-ion airplanes.

Nine days after the fire battery Boeing 787 at the airport in Boston, another aircraft of the same model of the Japanese airline All Nippon Airways had to make an emergency landing in Japan to detect that the lithium ions smoked.

Both incidents led to the FAA and other aviation authorities in the world to withdraw from circulation for three months the Boeing 787, while the US manufacturer redesigning the batteries, which incorporated insulating layers between cells, a steel box for contain any short circuit and improved ventilation.
