MATTITUCK - Police say the pilot of a small plane that went down in the waters off the Mattituck Inlet has died. No one else was on board the plane.

Coast Guard officials say the plane was an experimental fixed wing single-engine plane that crashed at around 9 a.m. Southold police say the plane was found floating about 7 miles northwest of the Mattituck Inlet. They say the plane’s parachute was deployed before it crashed.

The pilot has been identified as Zubair Khan, of New York City.

News 12 Long Island has learned the plane was registered to Shelter Air, which is based in Brooklyn.

Southhold Police Chief Martin Flatley says he believes Khan built the plane himself.

"It's a fiberglass body and a lot smaller structure than a regular sized plane," he said.

Officials towed the plane through Mattituck Inlet back to the shore, where NTSB investigators will inspect the aircraft. Police say they are still trying to determine where the plane came from and where it was headed.
