I don't see an answer yet so this is my best guess:
The aircraft or parts would be secured using robots and strops.
The aircraft would be hoisted slowly off the bottom and additional strops put in place. Further slow hoisting would take place until deep divers could reach it and check strops and add additional support as necessary. I would not expect them to enter at this stage as any failure could trap them . . .
Once near the surface they may attach buoyancy chambers and slowly inflate until slight negative buoyancy is achieved. Further raising and inflation until the aircraft is virtually on the surface.
They might enter at this point however that might also cause parts to break off and be lost.
The size of the aircraft would probably dictate provision of a barge and probably removal of wings and tail while still suspended on the water.
