No a repair is treated differently,( Different book), Although care passes to the gun smith control ie authority to dispose of
does not. Interestingly sending a gun out of state for consignment sale and pawn transactions also give the FFL/Pawn broker authority to dispose of and therefore require return via an FFL if return is inter-state.
