U.S. investigators examining the battery charger from a Boeing Co. 787 that caught fire this month in Boston have found no evidence of flaws that could have caused the incident.
The U.S. National Transportation Safety Board has completed testing of the charger at the Tucson, Arizona, plant where it was made by Securaplane Technologies Inc., the agency said Sunday. Securaplane is a division of Christchurch, England-based Meggitt PLC.
The NTSB also said it examined the aircraft's aft auxiliary power unit, which contained the lithium-ion battery that burned on the Japan Airlines Co. 787 in Boston on Jan. 7, at UTC Aerospace Systems and found nothing wrong. UTC Aerospace is a United Technologies Corp. subsidiary in Phoenix.
The 787 Dreamliner was grounded by the U.S. Federal Aviation Administration on Jan. 16 after a second battery incident occurred in Japan on an All Nippon Airways Co. flight.
