Two Long Islanders were killed and a third injured in a small-plane crash in Pennsylvania, authorities said yesterday.

The victims were students at SUNY Farmingdale’s Aviation Program.

The plane, which crashed near the Scranton airport Wednesday night, was on a flight not sponsored by the school.

The two who died were the 34-year-old pilot, Patrick Sheridan of Long Beach, and a 19-year-old passenger, Casey Falconer, of Garden City Park.

The survivor was 21-year-old Evan Kisseloff of Oceanside.
