The victims' names were not immediately released. The plane crashed at 7:45 p.m. about 1.5 miles west of the airport in the woods on the border of New Bedford and Dartmouth. It was cleared for landing at the airport.
"At some point as the aircraft was on final approach, we lost communication with it," FAA spokesman Jim Peters said. "All three were killed."
The turbo-prop Socata plane is owned by PK Leasing of Allentown, Pa., Peters said. It wasn't immediately known where the plane took off, he said.
