Dual engine failure during takeoff leads to fatal crash

3 fatalities • Iruma AFB (Johnson AFB), Sayama, Japan • Takeoff (climb)

An aircraft experienced a dual engine failure during its initial climb, resulting in a stall and subsequent impact in a field near an airbase.

What happened

During the initial climb phase following takeoff, the aircraft experienced a simultaneous loss of power in both right-side engines, specifically engines number three and four. This dual engine failure caused the aircraft to lose sufficient lift, leading to an aerodynamic stall.

The flight subsequently crashed into a field situated approximately five kilometers southeast of the airbase. The impact resulted in three fatalities among the crew, while eight others sustained serious injuries.

Findings

In addition to the loss of power in the two engines, reports indicate that the aircraft's electrical system also experienced a failure during the incident. The primary factor leading to the crash was the simultaneous failure of both right-side engines during the climb.

Probable cause

The simultaneous failure of engines number three and four caused an aerodynamic stall and subsequent crash.
