Well, this was fun. Redo of the left flap hinge so the flap hinge edge distance for the rivets attaching to the wing is correct, and matches the redo work on the right wing.
This required drillng out all of the rivets for the flap hinge (carefully), replacing the flap hinge (match drill, countersink, debur, etc., and riveting the new hinge in place.
This work we preciptated by the re-work required for the left wing flap brace.
