波音去年11月底说6-8周后提供MAX软件更新
照时程推算是一月 但那时候政府关门中..
目前还不敢肯定 软件更新延宕真的是因为政府关门
但软件更新延迟到三月或四月才发布是肯定的
所以MCAS的BUG现在还在....Orz

UPDATE 2-Boeing's 737 MAX back in spotlight after second fatal crash

CHICAGO/WASHINGTON March 10 (Reuters) - The latest version of Boeing Co’s
best-selling 737 family - a global industry workhorse - has again been thrust
into the spotlight after a fatal crash in Ethiopia, months after a deadly
crash involving an identical brand-new jet in Indonesia.
A Nairobi-bound Boeing 737 MAX 8 operated by Ethiopian Airlines crashed
minutes after takeoff from Addis Adaba, killing all 157 on board. The same
model flown by Lion Air crashed off the coast of Indonesia in October,
killing all 189 on board.
There are still unanswered questions about the causes of the Lion Air crash,
and officials and safety experts said it was too soon to draw links with the
Ethiopian incident.
Boeing did not respond to questions about the 737 MAX 8 on Sunday but said in
a statement it would send a technical team to the crash site to provide
assistance.
Boeing’s shares lost 12 percent in the weeks following the Lion Air crash,
but have more than recouped those declines, closing on Friday at $422.54, 18
percent higher than before the Oct. 29 incident in Indonesia.
Boeing’s 737 MAX is the newest version of a jet that has been a fixture of
passenger travel for decades and the cash cow of the world’s largest
aircraft maker, competing against Airbus SE’s A320neo family of single-aisle
jetliners.
The decades-old 737 family is considered one of the industry’s most reliable
aircraft.
Boeing rolled out the fuel-efficient MAX 8 in 2017 as an update to the
already redesigned 50-year-old 737, and had delivered 350 MAX jets out of the
total order tally of 5,011 aircraft by the end of January.
Former NTSB Chairman Mark Rosenker said the catastrophic crashes of two new
airplanes soon after the 737 MAX 8 was introduced were “highly unusual” and
both had broad similarities in that they went down soon after takeoff.
While it is unclear if there is a direct link, “this is now an extraordinary
issue” for aviation safety officials to grapple with and will prompt a
sweeping investigation to determine if there are common issues, Rosenker said.
Dallas-based Southwest Airlines Co is the biggest operator of the MAX 8, with
31 aircraft, followed by American Airlines Group Inc and Air Canada with 24
each.
Southwest and American said on Sunday they remained fully confident in the
aircraft and were closely monitoring the investigation.
Aviation analyst Scott Hamilton cautioned against drawing comparisons between
the two crashes, especially before the black box recorders are recovered.
Ethiopian has a strong reputation and good safety record, he said in a blog
post.
Still, the crash puts fresh pressure on Boeing just days before it had
planned an event to debut another aircraft.
Late Sunday, Boeing said it would postpone the planned ceremonial debut of
its 777x widebody aircraft that had been set for Wednesday in Seattle and was
to be livestreamed.
The company said it is focused on “supporting” Ethiopian Airlines and “
will look for an opportunity to mark the new plane with the world in the near
future.”
INVESTIGATION AND LITIGATION
Following the Lion Air crash, Boeing faced criticism from some U.S. pilot
unions for not having detailed in its flight manual a change in the way that
software on the MAX reacts in a stall compared with a previous version.
Boeing has insisted that cockpit procedures were already in place to deal
with problems that the Lion Air jet experienced.
A preliminary report into the Lion Air crash focused on airline maintenance
and training, as well as the technical response of the anti-stall system to a
recently replaced sensor, but did not give a reason for the crash. Since
then, the cockpit voice recorder was recovered and a final report is due
later this year.
Boeing was expected to introduce a software patch to help address the
scenario faced by the Lion Air crew in late March or April, government and
industry officials told Reuters in recent weeks.
Boeing is already facing a string of lawsuits in the United States by
families of the Lion Air crash victims, including five cases in U.S. federal
court in Illinois where Boeing has its Chicago headquarters.
The 737 MAX 8 uses LEAP-1B engines made by CFM International, a joint venture
of General Electric Co and Safran SA. (Reporting by Tracy Rucinski in Chicago
