The Viscount was parked at gate to board passengers when it was struck by a Seaboard & Western Airlines' Lockheed L-1049D Super Constellation which was performing training flight LN800 at Idlewild Airport. The Constellation began its takeoff run on runway 31R of the New York International Airport at 1100. When an airspeed of 117 knots (V 2) was reached, the aircraft became airborne and climbed to an altitude of approximately 25 feet. At this altitude severe control difficulty was encountered, causing the aircraft to veer suddenly to the left and the left wing to lower 20 to 30 degrees. This wing struck the runway and from this point on directional control of the aircraft was lost. The aircraft skidded In a westerly direction into a temporary terminal area and came to rest after striking the Viscount. All five crew members from the Constellation were injured while the Viscount was empty. Both aircraft were totally destroyed by fire.
The Board determines that the probable cause of this accident was an unwanted propeller reversal at a low altitude occurring immediately after takeoff. A contributing factor was the inadequate overhaul procedure employed by the propeller manufacturer.
