FAA orders checks on 9,300 Boeing 737 planes for possible switch failures:
WASHINGTON, July 15 (Reuters) - The Federal Aviation Administration (FAA) on Thursday issued a directive to operators of all Boeing Co (BA.N) 737 series airplanes to conduct inspections to address possible failures of cabin altitude pressure switches.
The directive requires operators to conduct repetitive tests of the switches and replace them if needed. The directive covers 2,502 U.S.-registered airplanes and 9,315 airplanes worldwide.
It was prompted after an operator reported in September that both pressure switches failed the on-wing functional test on three different 737 models.
The FAA said failure of the switches could result in the cabin altitude warning system not activating if the cabin altitude exceeds 10,000 feet (3,050 m), at which point oxygen levels could become dangerously low.
Airplane cabins are pressurized to the equivalent of not more than 8,000 feet (2438 m).
[...] Due to the importance of functions provided by the switch, the FAA in 2012 mandated all Boeing 737 airplanes utilize two switches to provide redundancy in case of one switch's failure.
The directive covers all versions of the 737 jetliners, including the MAX, but is unrelated to any issues related to the MAX's return to service last November.

Whereas now Boeing designs the plane, then removes the safety features they think they can get away with and sells them back at high markups (according to pilots vlogging about the changes over there). For the MAX... why is there only one angle of attack sensor when their new programming to 'fake' a 737 NG so no retraining is needed made that sensor so critical it'll result in a loss of the aircraft if the single sensor fails.
I'm curious: Will EA sue them for copying their business methods?

Huh? What does EA have to do with the angle of attack sensors?

you know; like EA pulls all the good parts of their games out and makes you buy it via DLC
