Exclusive: Boeing eyes Lion Air crash software upgrade in 6-8 weeks

SEATTLE/PARIS (Reuters) - Boeing Co (BA.N) is weighing plans to launch a
software upgrade for its 737 MAX in six to eight weeks that would help
address a scenario faced by the Lion Air crew during last month’s deadly
crash in Indonesia, two people briefed on the matter said on Thursday.

Crash investigators are focusing on the possibility that a new anti-stall
system that repeatedly pushed the Lion Air jetliner’s nose down was being
fed by erroneous data from a faulty sensor left in place after a previous
hazardous flight.

Boeing has said cockpit procedures that were applied on the previous flight
are already in place to tackle such a problem, and that its 737 series
remains safe to fly.

But U.S. regulators have said Boeing is also examining a possible software
fix, after coming under fire for not outlining recent changes to the
automated system in the manual for the 737 MAX, the latest version of its
best-selling passenger jet.

While plans for the possible fix are not final, Boeing’s software upgrade
could block the recently modified anti-stall system, known as MCAS, from
continuously running until the plane hits its nose-down limit, the sources
said.

The MCAS function would be disabled if the crew counteracted it by trimming
or adjusting settings in the opposite direction, according to two people
briefed on Boeing’s proposals.

“When the crew makes the adjustment, that would essentially disengage MCAS
unless it got new data,” one of the people said.

Data from the Lion Air flight recorder suggests the pilots sought to correct
the system more than two dozen times before the jetliner plunged into the
Java Sea on Oct. 29, killing all 189 people onboard.

Attention has focused on the role of a suspect “angle of attack” sensor
used to drive alerts on stall or loss of lift.

While each 737 has two of these blade-shaped vanes, the plane’s anti-stall
system relies on data pulled from just a single vane during each flight,
compared with a three-sensor “voting” system on rival Airbus (AIR.PA)
jetliners.

Boeing’s software update would come as an emergency measure from Boeing and
Federal Aviation Administration, the sources said.

SECOND PROBE
The specific system for preventing stalls was not originally designed to
monitor both probes because regulators assumed risks of a mishap were small
and would be further reduced by the presence of a trained crew and power
switches on errant systems.

Now, however, Boeing is examining whether the anti-stall system should also
check data from the second probe before engaging, according to a person
briefed on the matter.

Boeing declined comment on the proposed changes.

“As part of our standard practice following any accident or incident, we
examine our aircraft design and operation, and when appropriate, issue
bulletins and make recommendations to operators to further enhance safety,”
 a Boeing spokeswoman said.

“Boeing continues to evaluate the need for software or other changes as we
learn more from the ongoing investigation.”

The FAA has repeatedly said it will “take further action if findings from
the accident investigation warrant.”

Car demand collapse outruns GM's moves
A decision to update the software has not been finalised and Boeing could
choose a different strategy, the people said.

The world’s largest planemaker has 4,542 of the upgraded 737 MAX on order
from airlines, worth over half a trillion dollars at list prices, or about
half that after typical discounts.

Boeing has delivered 241 of the jets to customers since it entered service
last year, according to its website.
