A Prince George's County man was seriously injured yesterday when the single-engine plane he was piloting crashed near an airport in New York state, authorities said.

Jeremiah Murphy, 68, of Larchmont Road in Laurel was piloting a single-seater 1986 Falcon XP aircraft about 2:30 p.m. when the plane crashed in woods west of the Orange County Airport near Montgomery, located about 60 miles northwest of New York City, said Montgomery Fire Department Chief Bob Reynolds.

Murphy's destination and take-off location were not immediately available. He was the only occupant of the small plane.

Reynolds said Murphy, who was conscious and talking when firefighters arrived, sustained a broken leg, cuts and bruises and was taken by helicopter to Westchester Medical Center, where he underwent surgery. His condition was not available.

The cause of the crash is under investigation by the New York State Police and federal aviation authorities.
