I think the time has come to move on from the 737. Boeing was planning to do this but just opted to update the 737 design instead.

ABC news channel 24 last night showed a Boeing 737 Max8 from Silk Air arriving at Alice Springs they are being relocated from the wet and humid air of Changi to the dry air at Alice Springs. The news presenter advised that all six aircraft from Silk Air would be relocated to Alice Springs and that the auto pilot would be turned off. The relocation was mainly for protecting the asset from any serious corrosion from being stored at Changi.

Would suggest that Silk Air don’t expect to be bringing them back to operations anytime soon, if at all.

Another article on 737NG pickle cracks. It is mentioned that this issue does not apply to the P-8. I seriously doubt there are any P-8s with enough cycles to initiate this cracking. However, I believe there may also be some significant modifications to the P-8 version of the 737 which likely allowed Boeing to feel confident this cracking won't apply.

@John Fedup Methinks you forget to post the link to the article. NG.

I did indeed! Here it is.

Boeing has a whistleblower problem almost as big as Trump's. Some pretty damning comments about safety culture. There is interesting information about synthetic airspeed, a feature found on the Dreamliner but was rejected for the 737 MAX due to cost. When the cost for the MAX grounding along with legal settlements are finally summed up, the added costs for extra safety features and more design review will in hindsight be massively inexpensive in comparison.

Ada Retak di Pesawat Boeing Garuda dan Sriwijaya Air

Seems the cracking issue on NG already spread out. After getting the FAA notification, the Indonesian Aviation Authority also begin to check on NG's with priority of those with over 35,000 flight cycle.

Of 8 being reviewed so far, 3 has found crack. That close to 40% of targeted population. Seems now the Authority will spread the review check progressive to all NG population in Indonesia, which are more than 200 aircraft.

The Airlines suppose to begin phasing out the NG's with high usage hours with MAX. I think the prospect for A220 for the alternative is also being considered by some Airlines, since A320 family order backlog.
Wondering if this is also can give momentum for MC-21 and C919 for market outside their home countries.

Hard to say what opportunities Boeing's troubles will do for MC-21 and C919 sales. Bombardier struggled for C-Series sales although the situation was different. With Airbus support the product took off. With two assembly lines (Alabama and Quebec) together with Airbus support, I think customers may feel the A220 is a a safer bet.

Swiss inspects Airbus A220 jets as engine snag prompts grounding

Talking about A220, I do agree this airliner can provide alternative to Max or Neo that more safe bet compared to MC-21 and C919 for International Airlines out side Russia and China.

This latest incidence in Swiss A220 by looking at it seems more to the engine. This it will effect more US FAA on their certification issue, in my opinion.

A220 sit rather comfortably between Regional Airliner (E series, Sukhoi Superjet or The Japanese Regional Jet MRJ) and the Big Duo.
Still even consider by some Airlines as potential alternative on some routes, I think it will be limitations on streching above 160 seats for A220 to be a real competitor for Max and Neo.
That's why I still see momentum for MC-21 and C919 'at this moment', if MAX continous problem affected it's reputation with the passengers and Airlines Industry.

It's still up to market whether they will received back MAX or significant portion of them just loosing confidence in future use of MAX. It also will be uphill steep battle for MC-21 and C919 to convince Airlines Industry on the reliability of their Aircraft on the left long run.. especially providing realiable logistics chain support.

However, I just feel there's momentum for them at this moment, 'eventough' hard as it is, to try nib some International Market from Boeing even Airbus Single Aisles. This if the Russian and Chinese can play it well.

Boeing need to developed 797 soon, in my opinion. With E Jets already in their stable, 797 can provide them in medium future to kill off MAX and end 737. There's just a limit on how much they can keep upgrading 737.

Here's just a thought of mine..if developing 797 as clean sheets design is too much for their resources considering all their troubles now, why not developing 757 ?
After all, it's what the market wants, 757 replacement..They kill off 757 since the market that need long range medium Airliners was limited.. however with the growth of Air Traffic market toward longger point to point Airliners (which Max and Neo coming on)..757 capabilities seems what many looking on. 757 Neo or 757 Max seems can be catching.. just my two cents..:)

There is spectaculation in a Flight Global article (sorry, don't have a link) that a re-engined 767 with GE engines might be Boeing's quick and cheap NMA. Sounds kind of familiar doesn't?:oops: Probably a better concept than a over-stretched re-engined 737.

Yes I read that also. The speculation seems arise due to Boeing still have 767 line open, whille 757 production line already close for more than a decade.
I believe there's an Executive from Boeing rules that out. Beside if they go with say 767 Neo isn't that will cross too much with 787 ?

However if they developed 757 Neo, it will not cross 787 teritory, and together with E jets...they can cover MAX teritory. After all 757 was still newer design than 737, and have better upgrade potential than 737 (on my mind). It's already have the range and capacity that many Airlines look for current trend of point to point market.

Off course it's better if they go with clean sheet new design (797) for middle of the market. I'm bit bias in here..I like 757, shame the market trend and development change bit late.

I agree the 767neo would be an overlap with the 787. As for a 757neo, a supply chain that ended a decade ago along with a sort of redesign together with a with engine package.....probably not all that less expensive than a clean sheet design. The 767neo might be the only way to get a piece of the NMA market before Airbus swallows it whole.

I see Dennis Muilenberg has just been "demoted", so not sure how much of this will actually come to pass: Boeing ousts CEO Dennis Muilenburg from chairman post as 737 Max woes continue

They are applying a positive spin to this, but the reality is the BOD has quite clearly LOST its confidence in him with this move.

Oooh! The only A220 I've flown on was Swiss, last winter. Zurich-London.

Didn't like the interior much. OK for short haul, but I'd not like to have to spend a long time in it. A bit bleak, I thought. Dunno if that's standard or was chosen by Swiss. Ride was smooth, though.

Isn't A220 is aimed for 2000-3000 km range or 4 hrs flight ? I know it can do more, but I think based on what several airlines that already operate them, it'd the range they are being optimised.

Has not been on one yet, but if seeing the specs it's similar to DC-9 or MD80-90..5 seat abreast compared to 6 abreast on 737 and 320. However larger than 4 abreast of E series, Kawasaki MRJ/Spacejet or CRJ 900/1000. So four hours flight I think still tolerable.

Talking about long Fight:
https://simpleflying-com.cdn.ampproject.org/v/s/simpleflying.com/qantas-project-sunrise-complete/amp/?amp_js_v=a2&amp_gsa=1&usqp=mq331AQCKAE=#aoh=15716382473263&referrer=https://www.google.com&amp_tf=From %1$s&ampshare=https://simpleflying.com/qantas-project-sunrise-complete/

19 hrs+ from Sydney to NY and that's about similar time between Singapore to NY that SQ already done with their A350.

Considering what the initial result that Qantas have publicly posted, then seems they are going to have similar arrangements with SQ did on direct NY route, Business and Premium Economy.
No coach..but it's expected..14 hrs in coach seems what most people can endured.

Boeing's 737 Max troubles deepen, taking airlines, suppliers with it

This is already predicted..Boeing on going problem with MAX, now the problem on structural cracks on NG, no end can be certain with when MAX going to for again, falling behind on NMA market trend, and face even loosing it..now it's spilled to their suppliers and few Airlines stocks that relied heavy on their Airliners.

Particularly interesting comparing Southwest and Jet Blue..The first one relied on 737 while the second one with A320 family. I know it's not only the aircraft matter..Jet Blue business model also very big factors. However those two business model relied on efficient costs chains that includes simplify Airliners they are using.

Industry will take notice on whether relied on 737 family or A320 family will more beneficial on long run.
