It seems more and more likely the 737 MAX grounding will go well beyond six months and it can approach nine months to a year depending on developments in the next months.
The costs to Boeing for the MAX debacle are now approaching the costs of a new aircraft development.
Corners can't be cut when making airliners
The development of a new civil airliner requires somewhere between 50,000 and 100,000 work years. The total development cost lands below or above $10bn depending on the size of aircraft and its capabilities.
This is a lot of work years and a lot of money but the 737 MAX crisis shows there are no possibilities to avoid this magnitude of effort. There are no shortcuts possible in this business. The tiniest oversight or shortcut and it has major consequences.
The MCAS software fix for the 737 MAX pitch instability was such a shortcut. An aerodynamic solution to the problem could have been made but a software fix was easier and cheaper to implement.
