What are the precise circumstances under which the FAA allows MAXs to be flown (aside from test/certification flights)? Can Boeing move undelivered frames out of Washington state for storage (Victorville, Tucson,...)? Could they be delivered to airlines and the airlines would then store them (not that any airline would agree to do that).
When an aircraft model is grounded, it loses it's hull & flying insurance - ground cover only.
Presumably, Boeing are delivering frames to storage facilities under experimental / test cover, with test crew (probably a record number of test crew at work). Interesting to know if FAA consent to permit this, has been influenced politically.
Strategically, if Boeing are required to update software, and other elements of the aircraft, keeping undelivered aircraft close, will speed the process.
There is also an issue with technical delivery. Would a customer want to take delivery, as this is a significant financial and insurance milestone? Let Boeing manage the storage, funding and insurance.
Deliveries can’t happen because the airplane does not have a valid type certificate since it was suspended. Without a type certificate, airworthiness certificates for each airplane produced can’t be issued. Therefore no deliveries can be made. The airworthiness certificate (which is posted in the flight deck of the airplane) is usually issued about one day before the airplane delivers after completing test flights. That is the technical reason deliveries cannot happen, not insurance.
Before an individual airplane has its airworthiness ticket, airplanes can be flown under the production certificate. This is not because of political influence. Airplanes need to fly prior to the type and airworthiness certificates. There are still requirements and approvals needed before planes can fly but it is covered under a different set of regulations. New features, designs, modifications etc are always being made and flown prior to final approval of the certification plans. There are certification plans required, which require FAA approval.
Insurance and Political Influence of the FAA aren’t technically accurate assertions regarding why airplanes can’t be delivered, so please do not spread inaccurate information when you don’t understand the process.
