The plane that crashed into a home in Union Vale last month, killing two people, had engine problems moments after takeoff, according to a preliminary report by the National Transportation Safety Board.

The finding is based interviews with the passenger sitting in the cockpit — who told the NTSB both engines lost partial power at an altitude of only about 50 or 100 feet — and from the Sky Acres Airport manager, who saw the plane try to climb above some trees and a building before rolling on its side and going down.

Surveillance video also showed the pilot had difficulty starting the engines after refueling the six-seater twin engine Cessna.

The NTSB said the wreckage showed significant fire damage to the cockpit and engines, making it difficult to determine the position of the throttle and other controls.

According to the Federal Aviation Administration, the craft crashed into a home on South Smith Road on Aug. 17. The pilot and one person in the home were killed.

Both passengers aboard the plane were seriously hurt, as well as 21-year-old Hannah Bocker, who was inside the home that caught fire. She is being treated for severe burns at Westchester County Medical Center.
