Texting by a pilot before and during a 2011 medical-helicopter flight in Missouri contributed to its crash, the first time such distractions have been implicated in a fatal commercial-aviation accident, the U.S. National Transportation Safety Board found.
Tiny crystals that can cause lithium-ion batteries to short-circuit and fail are among areas under investigation in Boeing Co. 787 fire and smoke incidents, according to a U.S. agency conducting the probe.
Boeing Co.’s 787, already the focus of a special U.S. safety review, faces fresh scrutiny after Japanese airlines grounded almost half the world’s Dreamliner fleet for at least two days following an emergency landing.
U.S. aviation regulators aren’t pressing to get Boeing Co.’s 787 back into the air and won’t let the grounded Dreamliner jet resume flights until they know it’s safe, Transportation Secretary Ray LaHood said.
Battery incidents that prompted the grounding of Boeing Co.’s Dreamliner are “unprecedented” safety breaches that should have been prevented by the aircraft’s design, the U.S. investigation’s leader said.
