According to the report, as Ford's plane came in for the landing it passed over the top of an American Airlines 737 carrying 110 passengers and a six-person crew.
Los Angeles firefighters are seen near a plane that was piloted by Harrison Ford when it crashed at a golf course in Venice on Thursday, March 6, 2015.
The FAA told NBC News that Ford had been given clear instructions to land at the proper runway.
The Hollywood star, who holds a private pilot license, only just overshot the American Airlines plane after accidentally coming down on a taxiing lane instead of a runway in California, according to NBC News.
Though Ford, 74, was instructed to land on runway 20-L at John Wayne Airport in Orange County, Calif., he apparently made a mistake and aimed for a taxiway landing.
While this story is still now developing, we do know that Ford was aware of the plane underneath him, as he allegedly asked the air traffic controllers, "was that airliner meant to be underneath me?" Air traffic controllers informed Ford that he had landed on a taxiway rather than the runway, NBC said. "The FAA is investigating this incident".
In 2015 he crash-landed a World War II-era airplane on a Santa Monica golf course after the engine failed, suffering a broken arm and minor head injuries.
Ford, an experienced pilot, was flying a single-engine Husky. Camera assistant Eddie Aguglia told NBC News, "Looking at where he crashed and how the plane went down, I'm sure there was a moment where he said, 'I'm not going to risk lives, whatever happens, happens".
