U.S. officials are investigating a fire aboard a
Boeing Co. (BA) 787 Dreamliner in
Boston after a
Japan Airlines Co. (9201) flight from
Tokyo, the latest setback for the jet following several groundings last month.
Flames about two feet (0.6 meter) high shot out of an avionics bay in
the jet’s belly yesterday as the plane sat at a Logan International
Airport gate before its next departure, and there was a small explosion,
Massachusetts Port Authority Fire Chief Robert Donahue said in an
interview. Japan Airlines, which has seven 787s, won’t ground other
Dreamliners.
Boeing’s newest model has been plagued by incidents
since entering commercial service in late 2011, and a previous fire in
the avionics bay forced the test fleet to be parked in 2010. Electrical
faults in December forced
United Continental Holdings Inc. (UAL) and
Qatar Airways
Ltd. to ground 787s, the first jet with a fuselage made chiefly of
composite materials instead of aluminum and with an all-electric power
system.
“In-flight fires are very serious,” said John Cox, a
former airline pilot who now consults on safety issues with
Washington-based firm Safety Operating Systems. “Although this happened
on the ground, the idea that there was a fire on board means that this
needs to be carefully evaluated.”
Japan Airlines
said its 787 service to Boston from Tokyo today will fly as scheduled.
Yesterday’s return trip to Tokyo was canceled, Sze Hunn Yap, a
spokeswoman, said today in a telephone interview.
Smoke
The
smoke was traced to a fire from the battery used for the auxiliary
power unit, Japan Airlines said in a statement today, as the U.S.
National Transportation Safety Board and
Federal Aviation Administration began their own inquiries. The unit, which is made by
United Technologies Corp. (UTX), is designed to provide electricity when the engines are off.
GS Yuasa Corp. (6674)
made the battery involved in the 787 fire and it’s cooperating with the
investigation, Tsutomu Nishijima, a spokesman for the Kyoto-based
company said by phone. GS Yuasa isn’t aware of the reason for the fire,
he said.
The company’s shares declined 4 percent to 335 yen in Tokyo trading today, the biggest drop since Oct. 23.
Japan
Airlines gained 1.1 percent to 3,780 yen in Tokyo trading today. The
company has checked the batteries of five of its 787 aircraft and
inspection of the sixth will be completed by 6 a.m. tomorrow, spokesman
Taro Namba said.
ANA’s Checks
All Nippon Airways Co.,
the initial operator of the 787, received a communication from the
transport ministry to check all its 787s and the company will inspect
the batteries on all its 787s by today, spokesman Ryosei Nomura said by
phone.
ANA, as the carrier is also known, wasn’t doing anything
different with its fleet in light of the Japan Airlines incident, said
Nao Gunji, a spokeswoman. Boeing said it wasn’t making any changes to
its test-flight plans for other 787s, either.
The NTSB sent an investigator to Boston, said
Kelly Nantel, a spokeswoman. The FAA, the agency that certified the jet’s design in 2011, said it also is looking into the fire.
“Anything
that involves a fire does not get the luxury of being called a teething
problem,” said Carter Leake, an analyst at BB&T Capital Markets in
Richmond,
Virginia,
and a former military and commercial airline pilot. “Boeing needs to
get ahead of this quickly, because now you run the risk of getting into a
passenger aversion issue.”
Stock Drops
While last month’s Qatar Airways failure came on the plane’s delivery flight, a United jet had to make an emergency landing in
New Orleans while carrying passengers to
New Jersey’s Newark airport from Houston.
Debris
in an electrical panel on a Dreamliner sparked an in-flight fire in
late 2010, before the plane entered service, grounding the entire test
fleet for six weeks and forcing a redesign of parts of the system that
added six months to more than three years of delivery delays on the
plane.
Boeing fell 2 percent yesterday to $76.13 at the close in
New York in the biggest decline since Nov. 14. That pared the shares’ gain in the past year to 2.9 percent.
“We are aware of the event, and we are working with our customer,” said
Marc Birtel, a spokesman at Boeing’s commercial headquarters in
Seattle.
Flight 008
Flight
008 arrived at Logan International Airport at 10:06 a.m. Boston time
with 183 passengers and crew, Japan Airlines said in a statement.
Everyone was off the plane when a mechanic observed smoke in the cockpit
at 10:30 and alerted the fire department, Donahue said.
The
blaze broke out under the cabin in an avionics bay that also houses
batteries for the APU, said Richard Walsh, a spokesman for Massport, the
airport operator.
Firefighters from Massport and the Boston Fire
Department discovered smoke throughout the cabin and used hand-held
infrared detection devices to locate the blaze, Donahue said.
It took about 20 minutes to extinguish the fire, using a gas called
Halotron
that displaces oxygen in electronics fires. Shortly afterward, there
was a small explosion in the compartment that Donahue said probably came
from a battery pack. A dry chemical powder was used to put that out, he
said.
The 787 includes several lithium-ion rechargeable
batteries to power electronics and other equipment, according to FAA
records. The FAA imposed special conditions in 2007 on the use of
lithium-based batteries because they are a greater fire hazard than
other battery technologies.
No Heat
Lithium batteries burn violently and cannot be easily extinguished, according to FAA and NTSB tests.
The FAA said in
rules
published in the Federal Register that the batteries must be designed
to prevent overheating. If a battery did fail, it should not release
dangerous gases or damage nearby wiring, according to agency records.
Leake,
the BB&T analyst, said any connection between yesterday’s incident
and previous faults would mean that “the ante has been upped.”
“The
system should always be designed to isolate, and you should never
generate enough heat for a fire,” said Leake, who formerly worked at
Canadian planemaker Bombardier Inc. He has a buy rating on Boeing.
There
were no injuries yesterday, though one firefighter was evaluated for
skin irritation, Donahue said. Airport firefighters had trained with
Boeing on the Dreamliner, which familiarized them with the plane and
made their work more efficient, he said.
‘Introductory Squawks’
The
plane that caught fire was delivered to Japan Airlines last month, the
seventh 787 the carrier had received after getting its first in March.
It still has another 38 on order, according to Boeing’s website.
In July, an engine component on a 787 intended for
Air India fractured, spewing shards of metal and sparking a brushfire as the plane prepared for its first flight in
South Carolina. The FAA ordered in December that Dreamliners be inspected after fuel leaks on two planes were traced to manufacturing errors.
Boeing
Chief Executive Officer Jim McNerney has characterized the previous
incidents on the 787 as “normal introductory squawks” for a new model.
The
planemaker has delivered about 50 Dreamliners to eight customers since
All Nippon received the first one in September 2011. Boeing is doubling
the jet’s production rate this year to 10 a month to fill orders for
about 800 Dreamliners, which are valued at about $225 million at the
average list price.
