The landing gear of a single-engine airplane collapsed while coming in to Brookhaven Calabro Airport on Sunday afternoon, a Federal Aviation Administration spokesman said.
The FAA will investigate the cause of the rough landing, spokesman Jim Peters said. A single person was aboard the plane, he said. The pilot walked away from the aircraft after the landing and was not hurt, according to the Mastic Fire Department.
Suffolk police said the 911 call came in at 12:51 p.m.
The vintage plane came to rest on its belly, with its right wing on the ground.
The aircraft is a Cessna 305C, Peters said. Aviation websites describe it as a military aircraft that flew for the first time in 1949 and that the Army retired in 1974. It was a liaison and observation plane, the websites said.
The airport is owned by the Town of Brookhaven.
