Once search teams start bringing up remnants of AirAsia Flight
8501 from underwater, Indonesian authorities are expected to ask
U.S. experts to join the crash probe, according to government and
industry officials from both countries.
No such formal request has been made by Indonesia, these
officials said, and the final decision still could keep American
experts on the sidelines. But there has been ongoing communication
between the American and Indonesian sides, and various recent signs
indicate the situation could change quickly.
In the wake of a typical airliner crash, representatives of the
engine manufacturer routinely are requested to participate in the
investigation, along with the regulatory agency responsible for
overseeing testing and safety analysis of the engines installed on
the accident plane.
Yet so far, that isn't the case in the high-profile AirAsia
probe. Neither the U.S. National Transportation Safety Board, which
certified the jetliner's engines, nor General Electric Co., part of
the joint venture which built them, is on the multi-national probe,
which includes French and Indonesian entities.
Experts from Singapore and the U.K. also have pitched in by
providing technical advice or equipment.
Engines of the Airbus A320, which went down in the Java Sea in
stormy weather on December 28, were manufactured by CFM
International, a 50-50 partnership between General Electric and the
Snecma unit of France's Safran SA.
Some air-safety experts are puzzled by the delay in seeking U.S.
assistance. "That surprises me," said Mark Rosenker, a former NTSB
vice chairman, who dealt with Indonesian officials when the board
participated in the probe of an Adam Air jet that crashed on a
domestic flight in January 2007. This time, according to Mr.
Rosenker, "I also would have thought we would be part of the
investigation."
On Wednesday, a General Electric spokesman said "we fully expect
to join the investigative team" once wreckage is brought to the
surface, at which point the company "expects to be participating
with the NTSB" to help Indonesian officials dissect the crash that
killed all 162 people aboard the AirAsia plane.
"We are in communication with Indonesia," company spokesman Rick
Kennedy added, and "we have told them we're ready to go."
Through an email, an NTSB spokeswoman said board officials
"responded to the initial notification" of the accident, "offered
any technical assistance that may be needed" and are "awaiting
recovery of wreckage and/or recorders for further decisions."
Earlier this week, before search teams identified a portion of
the plane's tail section in roughly 100 feet deep water, the head
of the probe signaled he was moving toward asking for U.S.
participation. In an interview, Mardjono Siswosuwarno, the lead
investigator from Indonesia's National Transportation Safety
Committee, said U.S. experts would join at a later stage due to
their involvement with the engines.
