Looks like he flew one of his two Husky's, N89HU, down to SNA from Santa Monica.
The American flight he went over was AA 1456, not AA 1546 as reported in the link above and the incident occurred at about 2015Z on Monday.
He landed on taxiway C and overflew the B-738 which was holding on L short of 20L for takeoff on 20R.

He might very well have one. He got a Cessna 680 type rating at Flight Safety in Wichita a few years ago.
