Training flight stall and crash during engine failure simulation (45-21790)

Hamilton-Kindley Field, BermudaTakeoff (climb)

On July 14, 1950, a Boeing B-29 Superfortress (registration 45-21790) operated by United States Air Force - USAF (since 1947) was involved in an aviation accident near Hamilton-Kindley Field, Bermuda during takeoff. No fatalities were reported. Investigators recorded the probable cause as: The aircraft entered a stall during takeoff while the crew was practicing engine failure procedures.

An aircraft experienced a stall and subsequent crash during a local training mission while the crew was practicing procedures for an engine failure.

What happened

During a scheduled local training session, the crew was engaged in maneuvers designed to simulate the loss of power in one of the engines. As the aircraft type reached the point of lift-off, the flight experienced a sudden stall. This aerodynamic stall led to an immediate crash at the site of departure.

Despite the impact, there were zero fatalities and no injuries reported among the crew members on board. The incident occurred during the initial climb phase of the flight operations.

Findings

Preliminary details indicate that the loss of control was a direct result of the engine failure simulation being performed at the moment of lift-off, which led to the aerodynamic stall.

Probable cause

The aircraft entered a stall during takeoff while the crew was practicing engine failure procedures.
