Did this move come AFTER the US decided to ground the plane?.....

I think it might have even come after Boeing grounded them. Said Thursday for both. Anyway, way to take the helm as usual Japan!

Yeah, Japan only seems to move after the US does. I sure would like to see Japan take the lead on something especially since the safety of the people riding in their planes are at stake.

I will be very relieved when they understand the cause of those two crashes.

@Speed, wasn't it actually Japan that took the lead on grounding the 787 with the battery fires?

Yes. But that was because it involved ANA aircraft.

This is kind of a "moot point" as I do not believe these planes currently do fly through Japan's airspace.

Correct Tokyo-Engr. No flights from any carrier scheduled to fly here - so a very moot point. A formality for the Japanese to issue this directive and and just an excuse for the normal people to bash Japan on this website

Japanese companies supply a lot of parts for Boeing planes so it wasn't a huge surprise the government didn't take this action earlier.

The crash seems related more than anything to software, i.e., death by artificial computer intelligence or judgment deemed superior to the pilots. This is a scary thought.

Just a legal formality.

Nobody knows the root cause of the 2nd crash.

The first crash, Lion Air, has been said to be poor training and terrible documentation by Boeing. They are blaming the use of a single AoA sensor in the Lion Air crash. Lion Air didn't buy an upgrade to the software which would point out to the crew that the single senor was putting out anomalous readings, but crew procedures should have compensated for that.

There is no AI software in the aircraft. Flight control decisions are made based on well defined inputs. If those inputs are flawed, perhaps due to a single sensor being used, that is a hardware fault.

Boeing has always trusted the pilots ability to recognize failed sensors, disable those as control inputs, and let the pilot fly the aircraft manually. This requires a well-trained crew.

The Ethiopian Airlines copilot had just 200 flight hours. The voice recorders will help determine if that was any factor or not.

Just heard that Boeing is going to release a software update soon to address the anti-stall software glitch that has apparently been linked to these crashes.

The Software developers should be charged with Manslaughter.

The Boeing 737 Max includes a new “safety” feature about which the company failed to inform the Federal Aviation Administration (FAA).

The short version of the story is that Boeing had implemented a new “safety” feature that operated even when its plane was being flown manually, that if it went into a stall, it would lower the nose suddenly to pick airspeed and fly normally again. However, Boeing didn’t tell its buyers or even the FAA about this new goodie. It wasn’t in pilot training or even the manuals. But even worse, this new control could force the nose down so far that it would be impossible not to crash the plane. And no, I am not making this up. From the Wall Street Journal:

Boeing Co. withheld information about potential hazards associated with a new flight-control feature suspected of playing a role in last month’s fatal Lion Air jet crash, according to safety experts involved in the investigation, as well as midlevel FAA officials and airline pilots.

The automated stall-prevention system on Boeing 737 MAX 8 and MAX 9 models—intended to help cockpit crews avoid mistakenly raising a plane’s nose dangerously high—under unusual conditions can push it down unexpectedly and so strongly that flight crews can’t pull it back up. Such a scenario, Boeing told airlines in a world-wide safety bulletin roughly a week after the accident, can result in a steep dive or crash—even if pilots are manually flying the jetliner and don’t expect flight-control computers to kick in.

@mmwkdw, the recovery for encountering wind shear is to pull back until you get the stick shaker. Would the MCAS actually lower the nose in this instance?
