This isn’t correct. There’s one portion of the flight regime where the new engines result in different characteristics. To counter that, the MAX has an automated stick pusher. What’s the alleged fix? Pull the breaker on the overhead panel. There’s a similar failure mode in pre-MAX 737s called “runaway trim”. The giant trim wheels on the center pedestal spin in a loud and attention-getting fashion. The fix? Pull the breaker on the overhead panel.

> To counter that, the MAX has an automated stick pusher. The MAX does not have a stick pusher. MCAS works on the position (trim) of the stabilizer. The elevator feel system (which the NGs have as well) works by creating additional resistance at the yoke (which is hydraulically assisted). Neither are stick pushers. > There’s a similar failure mode in pre-MAX 737s called “runaway trim”. That's a thing that can happen on any plane with a similar horizontal stabilizer setup. I'm sure even a plane with a flying stabilizer (e.g. L-1011) has similar failure modes. > The giant trim wheels on the center pedestal spin in a loud and attention-getting fashion. The "giant" trim wheels were reduced in size on the NG (and MAX?) reducing their leverage. > The fix? Pull the breaker on the overhead panel. There are two switches (whose function was subtly changed with the MAX) that control the trim motors and they're located behind/below the thrust levers.
