Blame Darth Cheeto's government shutdown: :notsure:

Boeing to update 737 MAXs after delaying changes for months
Boeing plans to make major changes to the flight control systems on the 737 MAX aircraft — just months after delaying a similar software fix due to failed negotiations with the FAA, a report says.

Sources briefed on the talks told The Wall Street Journal that federal regulators determined that the delay was acceptable because its experts believed there was no imminent safety threat, as did Boeing’s.

The updates — which involve multiple sensors, or data feeds, being rolled out into the MAX’s stall-prevention system in place of its current single-sensor setup — were ordered up in the wake of the deadly Lion Air crash in Indonesia last October and were originally planned for early January.

“For the past several months … Boeing has been developing a flight control software enhancement for the 737 MAX, designed to make an already safe aircraft even safer,” the plane maker said in a statement late Monday. “This includes updates to the Maneuvering Characteristics Augmentation System (MCAS) flight control law, pilot displays, operation manuals and crew training.”

Sunday’s Ethiopia crash marks the second time in less than six months that a 737 MAX aircraft has gone down.

Differences of opinion about technical and engineering issues ultimately led to Boeing’s software change delays, according to the WSJ.
According to the WSJ, US officials have also blamed part of the delay on this year’s government shutdown — saying it halted work for at least five weeks.

The FAA insisted Tuesday in a statement that its ongoing review of the 737 MAXs “shows no systemic performance issues” related to the flight-control system and “provides no basis to order grounding the aircraft.”
OK, that's premature, since they haven't officially determined what caused the accident yet. Buuuut, . . . :notsure:

Ethiopian plane smoked and shuddered before deadly plunge (Reuters)
GARA-BOKKA, Ethiopia (Reuters) - The Ethiopian Airlines plane that crashed killing 157 people was making a strange rattling noise and trailed smoke and debris as it swerved above a field of panicked cows before hitting earth, according to witnesses.
Half a dozen witnesses interviewed by Reuters in the farmland where the plane came down reported smoke billowing out behind, while four of them also described a loud sound.

“It was a loud rattling sound. Like straining and shaking metal,” said Turn Buzuna, a 26-year-old housewife and farmer who lives about 300 meters (328 yards) from the crash site.

“Everyone says they have never heard that kind of sound from a plane and they are under a flight path,” she added.

Malka Galato, 47, a barley and wheat farmer whose field the plane crashed in, also described smoke and sparks from the back. “The plane was very close to the ground and it made a turn... Cows that were grazing in the fields ran in panic,” he said.

Tamirat Abera, 25, was walking past the field at the time. He said the plane turned sharply, trailing white smoke and items like clothes and papers, then crashed about 300 meters away.

“It tried to climb but it failed and went down nose first,” he said. “There was fire and white smoke which then turned black.”

Why Investigators Fear the Two Boeing 737s Crashed for Similar Reasons
The causes of both crashes are still under investigation. But the data cited by regulators points to preliminary indications that the two planes could have been brought down by the same cause, a malfunctioning automated system intended to keep the jet from stalling.
Marc Garneau, Canada’s transport minister, said on Wednesday that the satellite-tracking data revealed “vertical variations” in the Ethiopian Airlines flight reminiscent of those seen before the crash of the Lion Air Boeing 737 Max in Indonesia in October.

Points of similarity:

In both cases the planes were very new, just months after delivery, and although the pilots had thousands of hours of flight time experience on other aircraft, it was a new aircraft to them. About 2 months old in the first case, and 4 months in the second case.

Also the satellite tracking data looks similar.

It's 20 minutes of no bullshit.

Lays out the technical issues of the 737 MAX and why the older 737 systems don't have the problem.

Just an aside: There are issues that may have some relevance with self driving cars as well.

https://www.nytimes.com/2019/03/19/podc ... crash.html

Short version is that this plane was made to compete with a similar sized Airbus plane, which is more fuel-efficient than earlier models of the 737. The selling point was that pilots who already know how to fly the 737 won't need any retraining or flight simulator time. They even decided that pilots didn't need to know about the new MCAS system, so when they ran into problems, the pilots didn't even know that the system existed or that it was what was causing the problem.

What I don't get is that only three months earlier the Lion Air fix was in to avoid this catastrophic event. I can't fathom how they did not know, what with being pilots of that very publicized plane?


Maybe they were too busy looking for a sandwich.


Okay, that was just wrong, too soon, and just bad. I'm sorry.
