VANCOUVER, Wash. (AP) _ Two small planes collided while trying to land at a private airfield, authorities said. Five people were injured.

One plane, a Cessna 150, came down on top of a four-seat Cessna 172 at Evergreen Airport Friday afternoon, said county Fire Department spokesman Dave Sauerbrey.

The Cessna 172 pilot, Dave Mackin, his wife, Chrissie, and passenger Mark Hadley, received minor injuries, Sauerbrey said. The three are members of a Portland rock group called Bandit.

Student pilot Stephen Hartung, who was aboard the Cessna 150, was in critical condition at a Vancouver hospital, a spokeswoman said. The instructor, Robert Freier, was in serious condition at a Portland hospital.

The two planes were approaching the airfield from the west when the accident occurred about 4 p.m., Sauerbrey said.

Sauerbrey said there is no control tower at the airfield, where pilots land by sight.
