"- A component of the main electric trim system became inoperative. Our pilots ran the appropriate checklist, which included manually trimming the aircraft. They returned to MIA and landed uneventfully. The issue was not related to MCAS."

Indeed. This was a part failing on an aircraft in flight. It landed without incident, and was likely never in any sort of danger. Losing electric trim is an annoyance but also trims safety margins by, as I understand it, making autopilot impossible. So, it's good that they returned.

If this had happened on a 767 or A320 we'd never have heard about it.

Why re 767 or A320? (i'm guessing because they're not recently in the news.)

As I understand it the aircraft has a quite complex relationship with trim because of fundamental aerodynamic flaws (engines are too far forward). Am I right in saying other aircraft e.g. an A320 would handle this sort of failure without as much risk to the plane?

737 max had two fatal crashes due to automated trimming issues (MCAS) and the fleet had been grounded until very recently.

It's a new aircraft not one 20years in service like your average 767 or A320!

Guys, this is a very common and well-known problem. It's been around for over 4 years now. The good news is that instead of nosediving into the ground the 737s can now land and be swapped out. The main take away here is that there are no more fatal crashes. This is a solid improvement for Boeing.

I agree but it’s like the galaxy phone that had the battery issue. It just killed confidence with the consumer.

The investigation (and what we learned form it) into Boeing also didn’t help with confidence levels.

After a few new iterations nobody talks about the battery anymore. I’m not so sure how Boeing can turn this around relatively quickly.
