Boeing Investigation Update from Japan


During an early inspection of the 787 in Takamatsu by Japanese officials, the battery’s electrolyte had leaked from the lithium-ion battery.

The charred insides of the battery show the battery received voltage in excess of its design limits.

In October 2011, the FAA issued an emergency order requiring lithium ion batteries in 42 Cessna Citation CJ4 to be replaced with nickel-cadmium or lead-acid batteries, after a connection with a ground power station led to overcharging and a fire.

Wait…was this human error and not battery error? Or a combination of both?

    NTSB ISSUES UPDATE ON ITS INVESTIGATION OF FLIGHT 27 THAT DIVERTED TO DULLES AIRPORT

    NTSB ADVISORY
    National Transportation Safety Board
    Washington, DC 20594
    May 21, 2010

    In its continuing investigation of a fire aboard a Boeing
    757 that diverted to Dulles Airport (IAD) enroute to the Los
    Angeles International airport (LAX) from New York’s John F.
    Kennedy International airport (JFK), the National
    Transportation Safety Board has developed the following
    factual information:

    On Sunday, May 16, 2010, about 9:17 pm (EDT) the pilots on
    United Airlines flight 27, a Boeing 757, N510UA, noted a
    strong acrid smell and observed smoke from the Captain’s
    lower front windshield. The incident occurred about 30
    minutes into the flight while the aircraft was level at
    36,000 feet MSL. On board the aircraft were 7 crew members
    and 105 passengers.

    The Captain and First Officer reported that they donned
    their oxygen masks and smoke goggles immediately after
    observing the smoke and fire. The Captain then gave control
    of the airplane to the First Officer and discharged a halon
    fire extinguisher. The smoke and fire dissipated but then
    re-ignited. The Captain obtained a second bottle from the
    Purser. The fire remained extinguished after this second
    bottle was discharged. At approximately 500 feet MSL on
    final approach to Runway19L at IAD, the Captain’s windshield
    cracked. The landing was uneventful. The airplane cleared
    the runway, after which ARFF (Aircraft Rescue Firefighting)
    entered the aircraft to check for residual heat and fire.
    None was found and the airplane was towed to the gate for
    deplaning. There were no evacuation and no injuries to the
    flight crew or passengers.

    Preliminary examination of the cockpit area revealed that
    the inner pane of the Captain’s windshield had cracked. One
    of the five terminal blocks attached to the inside of the
    lower left windshield was consumed by fire and the portion
    of the wire harness associated with this terminal block was
    significantly damaged by fire. There was significant sooting
    and paint peeling to the left hand side of the windshield
    air frame support.

    The Captain’s windshield was moved and will be examined by
    Board investigators at the manufacturer.

    Two previous windshield fire events on B757-200 aircraft
    prompted the NTSB to issue Safety Recommendation A-07-50
    http://www.ntsb.gov/recs/letters/2007/A07_49_50.pdf. The
    Safety Board investigators will look closely at the
    recovered hardware to determine if this latest event is
    related.
