Take attention to the items you discovered with a good IA. Make corrective repairs based on good airframe practices. Fly the airplane within the limitations stated in the STC for the mod's.

If you have to do anything it would probably be remove the winglets. The NTSB may find that mixing STC's may be ................, but who knows. There are lots of Skymasters flying with extended wing tanks and lots with winglets but very few with both. Removing the winglets would be the least amount of pain.

Just some thoughts.
