A B-50 aircraft crashed into a field six miles southwest of Eielson Air Force Base during a local training sortie, resulting in the deaths of all ten people on board.

What happened

The incident occurred while the crew was conducting a local training flight out of Eielson Air Force Base. During the sortie, the pilots lost control of the aircraft. The plane subsequently crashed into an open field situated six miles southwest of the airbase. Tragically, all 10 occupants aboard the aircraft were killed in the accident.

Findings

Investigations indicated that mechanical failure was the primary factor leading to the loss of control. Specifically, oil congealed within the small tubing of the aircraft's manifold pressure regulator. This blockage disrupted normal engine operations and contributed directly to the crash. Following this event, modified regulators were installed on all B-50 aircraft to prevent similar occurrences.

Probable cause

The crash was caused by congealed oil in the small tubing of the manifold pressure regulator, which led to a loss of control.
