Harrison Ford was involved in a “potentially serious” incident while piloting his private plane on Monday which is now being investigated by the Federal Aviation Administration, according to a report by NBC Nightly News.

The actor mistakenly attempted to land on a taxiway at John Wayne Airport in Orange County, which put him near a full passenger plane, according to the report. The FAA told Variety that it does not identify people involved in aircraft incidents or accidents, but issued the following statement on Tuesday:

“Air traffic controllers cleared the pilot of a single-engine Aviat Husky to land on Runway 20L at John Wayne Airport Monday afternoon. The pilot correctly read back the clearance. The pilot then landed on a taxiway that runs parallel to the runway, overflying a Boeing 737 that was holding short of the runway. The FAA is investigating this incident.”

The passenger plane, American Airlines 737, was reportedly loaded with 110 passengers and a six-person crew. Ford was allegedly heard on an air traffic control recording saying, “Was that airliner meant to be underneath me?” Controllers then apparently informed Ford that he was landing on a taxiway instead of runway 20-L.

Ford’s rep declined to comment on the situation on Tuesday.

The 74-year-old “Star Wars” actor has had decades of flying experience, but has also had a series of crashes and close calls. Most recently, in March 2015, he made an emergency landing in a World War II-era airplane on a Santa Monica golf course after its engine failed. Ford suffered a broken arm and minor head injuries, but has since made a full recovery.
