737 Max return to service might be 'phased,' CEO concedes

[Yo_Mama_Been_Loggin]

Boeing chairman and chief executive Dennis Muilenburg on Wednesday reiterated his projection that, despite concerns publicly expressed by Europe’s air safety regulator, the 737 Max should begin to return to service around November.

However, he conceded that lack of alignment among international regulatory bodies could mean that the grounded jet may first resume flying in the United States, with other major countries following later.

“We’re making good, solid progress on a return to service,” Muilenburg said, speaking at a Morgan Stanley investor conference in Laguna Beach, California. He later added that “a phased ungrounding of the airplane among regulators around the world is a possibility.”

A week ago, the European Union Aviation Safety Agency (EASA) publicly criticized the certification process of the 737 Max. And the agency said that it would favor a redesign of the airplane’s systems to take readings from three independent Angle of Attack sensors rather than the two-sensor system in Boeing’s proposed upgrade to the Max.

Muilenburg played down the possibility that this could mean potentially expensive hardware changes to the airplane in addition to the planned software upgrade.

Referring to the fact that the Airbus A320 —the direct competitor to the 737 —has three Angle of Attack sensors, Muilenburg said that “our architecture on Boeing airplanes is different than Airbus airplanes,” and added “that doesn’t necessarily mean hardware changes.”

1. They should be scrapped

And never flown again.

[Yo_Mama_Been_Loggin]

2. They've been flying for more than 50 years

8. Not this kitbashed version

With the center of gravity changed to install the new improved efficient engines that now requires a software fix to the flight controls the make the thing not fall out of the sky.

It is a badly engineered aircraft that had overstretched a 50 year old design.

13. The F-117 was fly by wire too

This can be fixed.

15. Fly by wire isn't the problem. The big new engines make the plane unstable and prone to stalling.

Boeing threw in a lot of technology to make it behave more like a 737, including the undisclosed anti-stall system, and gave it insufficient redundancy.

Fundamentally, the MAX is a kludge marketed as the trusty 737. Boeing is patching the most obvious fatal flaws. As another post notes, Europe wants more. Also, pilots will need retraining as the MAX is a new beast.

4. There is no way in the world that was going to happen.

These aren't Corvairs and they aren't de Havilland Comet's, either.

The 737 is a tried and true airframe, and though the two accidents that happened are tragic, Boeing can and will make these aircraft safe to operate.

9. See post 8

10. Sorry, Charlie. Post 8 does not address post 4 ion any relevant way.

Simply saying it does, does not make it any more true. You simply fail to supply data or evidence to support your bumper stickers (see: Rational Thought in the Enlightened Age).

3. Understrand there is a backlog on the 737 max

orders out to 40 months. Air Bus has a similiar backlog.

Folks,it is all about the Money and to hell with safety.

[A HERETIC I AM]

5. Nonsense

Did Boeing screw up? Yes they did. But suggesting they did so with a completely cavalier attitude toward safety is a serious stretch.

6. Where they screwed up was deciding to make the plane 10 years ago!

Delta was to profit focused and decided to try and cobble up a new plane using the 737 body with new engines and wing configuration that made the plane subject to too rapid ascent. Necessitating even more rigging this time with software.

Whereas Airbus invested the money in a brand new and vastly superior airplane (even before the Max was learned to be a death trap).

This may not bankrupt Boeing because the Government will not let that happen. But they are in a bad spot. Airbus will own them for the next generation because to many airlines and passengers like me will never fly on a 737 Max. Assuming they are ever actually flyable.

7. When Boening's

chief Test Pilot took the Fifth,and refused to answer direct and indirect questions about his approval of the Max Software,that kicked the door wide open on Boeing trust issue. Not suggesting a Cavalier Attitude one bit,but,we now see they were doing their level best to save 2.5 billion in Pilot Training costs just to get their new plane certified in order to stop their Air Bus Competitor from stealing their market.

11. They're not going to add redundancy for that sensor? Swell.

That's likely to be it's well deserved death knell. If they put the damn things back in the air like that passengers will stay away in droves and airlines will be forced to dump the jets and sue the crap out of Boeing.

[Owl]

12. Exactly!

[Yo_Mama_Been_Loggin]

14. Boeing will do two sensors while the the European Union Aviation Safety Agency want 3

It's very rare I've seen triple redundancy on any system
