A helicopter crashed at Chandler Municipal Airport on Thursday, slightly injuring a passenger.
The two-seat RotorWay Executive 162F tipped on its side at 8:20 a.m. as a flight instructor and student practiced hovering, Federal Aviation Administration spokeswoman Ian Gregor said.
The student suffered minor injuries, while the teacher was unharmed.
The helicopter was "significantly damaged," Gregor said, with its rotor blades taking the most damage. There was a fuel leak, but no fire.
The helicopter's registered owner is listed as Cobb International, doing business as RotorWay International. The Chandler-based company bills itself as "the world's oldest and largest kit helicopter manufacturer."
A phone message left with the company was not immediately returned.
Investigating the crash are the FAA and the National Transportation Safety Board, Gregor said.
