FAA addresses dual-engine shutdown of A220 P&W engines

Thankfully it’s not Boeing this time. The haters would have been all over it.

Luckily in the Fokker F28 (circa 1986) we did not have any autothrottle system. So this problem would never have arisen.

In CT7 language it was a uncommanded
rollback. Since the ECU/FCU actually acted as programed. Like 737MAX programmers now crash airplanes too. Automation big lie that takes pilots out of the loop.

147 engines? Who is running the mismatched set?

Rube Goldberg strikes again. Keep It Simple Stupid.

Seems not so much an engine/engine manufacturer issue, but the AIRCRAFT avionics software issue (Airbus). The article starts out seeming to blame the engines!

Why did this take 1 1/2 years for the AD to get issued?

According to the FAA, following an investigation into the matter, it determined that “the sequence of the auto-throttle increasing throttle to maintain Mach number, immediately followed by pilot command to decrease throttle to idle, caused a transient disagreement between actual and commanded thrust.” As a result, the disagreement triggered a thrust control malfunction (TCM) detection logic, and the aircraft shut down both engines as soon as wheel sensors detected that the aircraft had physically landed on the runway.

And this over reliance on technology and not a pilot's skill will eventually lead to deaths in the future. In the not too distant future you will see a monkey in the cockpit trained to start the engines and shut them down after the plane does all of the taxiing and flying and landing on its own.

Is this the least expensive AD note in the history of flight?

So how long are these planes going to be grounded until there fixed

wow. How about the software check if there is any airspeed too....
Software is never bug free but this is a design issue.
