The dead are pilot and plane owner John Ambroult, 60, of Eastham, Massachusetts, and 41-year-old Stephen Claussen of Seattle.
Two other passengers were injured when the plane crashed in a heavily wooded area near a small airport in southern Ocean County late yesterday afternoon.
The injured were identified as Jacalyn Brown, 28, of Pemberton and Juan Carlos Salinas, 43, of Mexico City.
No word from state police Sergeant Stephen Jones on the extent of their injuries. State police were able to speak with Salinas after the crash.
It was not immediately clear what caused the crash.
Stephen Williams, director of airports for the Delaware River and Bay Authority, says the plane was flying as part of a federal study of coastal birds and wind currents along the Jersey Shore, where developers have proposed installing wind turbines.
