Authorities say the two men aboard a single-engine plane suffered minor injuries when it crashed in a lake on the outskirts of metro Phoenix and then sank.
The Maricopa County Sheriff's Office said the plane crashed Saturday in Lake Pleasant and that lake patrol deputies helped the men get out of the water and into sheriff's boats.
Sheriff's Sgt. Joaquin Enriquez said no information was immediately available about circumstances of the crash, including what the plane was doing beforehand and whether it had mechanical trouble.
Federal Aviation Administration spokesman Ian Gregor said the FAA and National Transportation Safety Board will investigate the crash.
