43 fatalities

Takeoff aborted due to unresponsive controls ends in fatal crash (NC30046)

New York-LaGuardia, United States of AmericaTakeoff (climb)

On May 29, 1947, a Douglas DC-4 (registration NC30046) operated by United Airlines was involved in an aviation accident near New York-LaGuardia, United States of America during takeoff. 43 people were killed. Investigators recorded the probable cause as: The accident was caused by either the pilot failing to release the gust lock before takeoff or the decision to discontinue the takeoff due to apprehension regarding rapid use of a short runway under possible calm wind conditions. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 3 related events involving the same aircraft type or operator are linked below.

An aircraft failed to lift off after the pilot reported heavy controls and locked brakes during an aborted takeoff, resulting in a runway excursion that killed 43 people.

What happened

The aircraft taxied from its parking position and entered Runway 18 without delay. The crew advanced the throttles for takeoff, and airspeed increased to over 90 miles per hour. The pilot applied back pressure to the control column but reported that the controls felt heavy and unresponsive. As the aircraft approached the end of the runway, the decision was made to abort the takeoff.

Brakes were applied approximately 1,000 feet from the south end of the runway, and the engines were cut. An attempt to induce a ground loop using the left brake failed as the aircraft continued straight ahead. Despite locking both brakes, the plane rolled off the runway, crashed through the airport perimeter fence, and crossed the Grand Central Parkway. It came to rest 800 feet beyond the runway end, near the Casey Jones School of Aeronautics, and was quickly engulfed in flames.

Five individuals, including the pilot, another crew member, and three passengers, were rescued from the wreckage. 43 other occupants lost their lives in the incident.

Findings

The investigation concluded that the accident resulted from either the pilot's failure to release the gust lock prior to takeoff or the decision to abort due to apprehension about using a short runway under potentially calm wind conditions.

Probable cause

The accident was caused by either the pilot failing to release the gust lock before takeoff or the decision to discontinue the takeoff due to apprehension regarding rapid use of a short runway under possible calm wind conditions.
