US actor Harrison Ford is being investigated over an incident last week at an airport in southern California.

The US Federal Aviation Administration said he was piloting a small plane that wrongly crossed a runway where another aircraft was landing.

The planes were within about 1,100m of each other at Los Angeles' Hawthorne airport last Friday.

There was no danger of a crash.

Ford who is 77 years old acknowledged his mistake and apologised.
