Boeing 787s grounded

On Jan. 16, the FAA ordered that Boeing 787s (aka Dreamliners) be taken out of service until it can be determined what caused the lithium ion batteries on two planes to overheat and release flammable electrolytes and smoke.

This occurred in the auxiliary power unit’s battery on a Japan Airlines 787 while parked in Boston on Jan. 7 and in the main battery of an All Nippon Airways 787, forcing an emergency landing in Japan on Jan. 16. No one was hurt.

All eight airlines around the world that use 787s ended up grounding the planes, 50 in number. It may be months or a year before investigations are completed and the planes are cleared to fly again. Smaller problems reported with 787s include a brake malfunction, fuel leaks and a cracked cockpit window. 787s began flying in October 2011.
