Ford, 73, who sustained critical injuries in a plane crash on March 5, touched down his helicopter at a wedding site in Saddlerock Rock Ranch in Malibu, California, reported Us magazine.
"The reception was about to be held in the same area where they allow choppers to land. His wedding gift for the newlyweds, was a picture with the bride and groom!," a source said.
Regardless of the "Indiana Jones" actor's accident in March, his wife Calista Flockhart says she stands by her husband's choice to fly.
The actor, who will next be seen in "Star Wars: The Force Awakens," was hospitalised with a broken pelvis and ankle after he was forced to crash-land his plane.
