Let's recertify our jet instead of doing a new one, shorten time to market.
New engines don't fit, ruin the handling of the aircraft. Can't recert that.
Try to fix aircraft handling in software. Designed flawed system to hide this from pilots and get regulatory apptoval. Under testing discover that system as submitted to regulators does not work well enough in flight. Update to allow to run repeatedly instead of once as well as increasing movement ranger per cycle. Do not tell regulators.
Ship aircraft with 1 hour iPad video intro for pilots. Do not mention this system.
Discover that the indicator in the cockpit for sensor failure for the system only works if you have optional HUD upgrades. Sit on this data. Do not patch until your aircraft is grounded.
Reassign the guys who are supposed to be doing safety oversight for you if they ask for more safety testing.
There still in business though, so Boeing will probably pull out of this fine.
Boeing itself should be fine after a couple of really expensive years. VW was as well and I for my part really thought VW could go under. Instead it hit some high level managers and around 30 billion in fines.
