Faa finds another major [737] problem

FAA finds new 'potential risk' in Boeing 737 Max, a setback that could delay plane's return to the skies

https://www.usatoday.com/story/news/...es/1577597001/

Do you think it would be possible for Boeing to just remove the Leap engines , change the pylon and put on the old CFMs and call it a 737-800 ish? Sell them cheap and then do a clean sheet design ? It’s really not
Looking good at this point.

Any engineer types know ?

Sure, all it takes is money.

You could change out the engines, and the worst you would have is a -900 with slightly reduced performance...........Hmm, wait.........

Supply chains don’t work that way. Production lines have been shut down and retooled. The NG can’t just be turned back on and neither can the CFM56-7 line. Old is out, New is in.....

Short Term:
Utterly impractical on many levels. Most significantly, if the NG could compete with NEO, they wouldn't have built the max in the first place.

Long Term:
Lots of (government sponsored) new technology on the horizon to dramatically reduce fuel burn/carbon/emissions. It will take a LOT of R&D money to implement (likely drastic changes to aircraft configuration), so both Boeing and Airbus decided not to drop tens of billions in a clean-sheet narrowbody which might be obsolete in ten years. Normally they would have, and just saved the new tech for the NEXT generation a few decades down the line but regulatory and/or political pressure is very likely to force the implementation of said technology as soon as it's ready (2030, maybe sooner?).

Where were these Mighty Feds during the certification process?

Yes, after the shenanigans with MCAS certification came to light I had my suspicions that the inevitable scrutiny might uncover other similar issues.

So much excitement to throw wood on the fire, did anyone actually read the article and note that it's full of errors and bad information, and old information, inaccurate descriptions and straw man references? No?

Too busy posting a link and living off the title, rather than bothering to read the article?
