Yeah i thought that, but wouldn't the slings creat
stress points that would damage the plane? Cause
the "skin" where the slings are placed to buckle?
There would also be high stresses at any hoist points if they were used instead of slings.
I can only speak to the engines and nacelles - each sub-component has hoist points built in so that large parts can be removed safely with a crane and put on or taken off of dollies or fixtures. And the hoistsp oints and surrounding structure are designed to carry the loads.
My educated guess is that there must be hoist points on major sub-sections - nose, forward fuselage, aft fuselage, wings, pylons, tails, etc. Let's watch and see what happens - we'll all learn something.
