They may be able to get them recertified and into the air again - but their biggest battle will be convincing pax that they are now as safe as the original B737. That could take some doing. Boeings credibility is in tatters, like a battlefield flag.
I reckon there must be a few Boeing people who secretly (or maybe now not secretly) wish they had bitten the (expensive) bullet & designed a brand new narrow body Jet when they made that Max decision. The bean counters won out though & after the excrement hit the fan and the fiddles and failures eventually surfaced it was all over rover.
A complete redesign would be a formidable cost. The improvement was all related to the engine's efficiency, so hard prospect to sell a full redesign and it would take too long. The low floor easy access advantage proved to be a limiting concept with the bulkier motor and it's forward location requirement.. The FIX was poorly executed and deceptively marketed. Quality control issues are mixed with all this as well as no FAA overwatch.. Most pax would not know or care what brand of plane they are flying in as long as the ticket is cheap. The issue is about Liability and being sued. Nev
It's changed..... IF it's Boeing, I'm not going. ALL pilots I know were of the same opinion. Actually, although the 737 is very popular it's had previous (unrelated) problems. Rudder actuator malfunction.. Nev
Boeings philosophy change has been around for almost 20 years but they were able to sack whistle blowers and keep the many issues under wraps even in the face of press reports and TV docos until the Max crashes. The problems are not just confined the Max either with the 777 & 787 found to have issues.
They have been a bit paranoid about removing the union power from the company for any years. It was even obvious in their Australian ventures. Subbing out NEW small recently formed entities with lower pay and cost structures make quality hard to preserve. They didn't want to see the signs and let it get ahead of their business plans which is solely focussed on returns to shareholders and their OWN (linked) remuneration. rates , with inadequate attention to the risks. ALL OK it you can get away with it .What is the REAL cost to the company NOW.? .Nev.
