We now have a situation in which the crew were predisposed to an understanding that an 'unreliable airspeed' issue had arisen on previous flights. It now appears that as you correctly allude to, the crew were led unawares into a checklist and remedy that DID NOT address the underlying issue. The Boeing 'fix' was not an immediete grounding and rectification but rather now 'recommend' a crew ignore the cacophony of noise, stick shakers, aural alerts and instead go to another checklist. In the heat of the battle, remembering which is which is not only difficult but is crap. The distraction from a cascade of warnings mostly spurious is a dangerous precedent.

There once was a time where a prudent Boeing would have grounded the fleet, rectified the problem.
That Boeing is long gone.
Infected by the requirements of a capital market and 'commercial returns' the smart money men have focus on the BA NYSE price and personal financial incentive. it is worth considering that Boeing were perhaps well aware of the issue.



Remember. Now it just occurs in plain sight, no attempt to hide, or even explain. Airframer say jump, FAA say: “How High?”
Trust, But verify. Unless it’s too expensive? Not the first time a system was untested while carrying passengers.


Regulatory capture plain and simple.
