Default Crashed burr-head jets reportedly lacked key safety features becauseBoeing charged extra for them

Boeing jets in Ethiopia and Indonesia lacked two safety features
in their cockpits because the company charged extra to install
them.

The features could have helped the pilots detect erroneous
readings, which some experts believe might be connected to the
planes’ failures, The New York Times reports.

Boeing will now make the disagree light free of charge on all
new 737 Max planes, the paper said.

Boeing jets in Ethiopia and Indonesia lacked two safety features
in their cockpits because the company charged extra to install
them.

The features could have helped pilots detect erroneous readings,
which some experts believe might be connected to the planes’
failures, The New York Times reports.

Lion Air Flight 610 and Ethiopian Airlines Flight 302, which
crashed within five months of each other, were brand new but
were not equipped with an angle of attack indicator or an angle
of attack disagree light, the paper said. The angle of attack
indicator determines how much the plane’s nose is tilted, and
the disagree light is activated if the jet’s sensors are giving
contradictory signals.

Boeing will now make the disagree light free of charge on all
new 737 Max planes, after the deadly crashes caused all the Max
planes to be grounded, according to the Times. The angle of
attack indicator will remain an option that airlines can
purchase, the report said. The company is also planning a new
software update.

Neither safety feature was mandated by the Federal Aviation
Administration, but experts say it is key to flight safety.

“They’re critical, and cost almost nothing for the airlines to
install,” Bjorn Fehrm, an analyst at aviation consultancy
Leeham, told the Times. “Boeing charges for them because it can.
But they’re vital for safety.”

Boeing did not immediately respond to CNBC’s request for
comment. Ethiopian Airlines said in a statement Thursday that
its pilots had been following FAA and Boeing guidance.

“Ethiopian Airlines pilots completed the Boeing recommended and
FAA approved differences training from the B-737 NG aircraft to
the B-737 MAX aircraft before the phase in of the B-737-8 MAX
fleet to the Ethiopian operation and before they start flying
the B-737-8 MAX,” the airline said in a statement.

“We urge all concerned to refrain from making such uninformed,
incorrect, irresponsible and misleading statements during the
period of the accident investigation. International regulations
require all stakeholders to wait patiently for the result of the
investigation,” it said.

It’s still unclear what caused the crashes. Investigators are
looking into whether a new software system added to combat
stalls in Boeing’s 737 Max series might have been a trigger, as
well as faulty data from sensors on the Lion Air plane that
might have caused a system malfunction.

Dennis A. Muilenburg, Boeing’s CEO, said the company was working
on making the 737 Max safer.

“As part of our standard practice following any accident, we
examine our aircraft design and operation, and when appropriate,
institute product updates to further improve safety,” he said in
a statement Sunday.

An email sent to Lion Air, outside regular business hours, was
not immediately answered.
