Ottawa County officials say two men were on board a small aircraft that crashed at Park Township Airport at 1269 Ottawa Beach Road in Holland.

It happened just after 7:00 p.m. Wednesday night, as the aircraft landed. Officials say it veered off the runway into the grass, where it overturned.

The pilot of the plane, 63-year-old Richard Henley, of Holland, was flown from the scene by Aero Med to Spectrum Butterworth with serious injuries. His passenger and the owner of the plane, 71-year-old Leyland Klink, of Spring Lake, was treated at the scene for minor injuries.

We're told the aircraft was a Evolution Revo lite sport edition ultralite.

The FAA and NTSB are now investigating.
