Fatal aircraft accident near Vantaa Airport

3 fatalities • Helsinki-Vantaa, Finland • Takeoff (climb)

An aircraft crashed following an engine failure during its initial climb from Helsinki, resulting in no survivors.

What happened

During the departure phase from Vantaa Airport in Helsinki, the flight crew encountered significant mechanical difficulties. Shortly after departing the runway, the pilot communicated that the aircraft was experiencing engine-related issues and requested permission to perform an emergency return to the airfield.

While attempting to manage the situation, the airplane experienced a rapid loss of altitude. The aircraft subsequently impacted the ground near the airport, resulting in a post-crash fire. There were three fatalities among the occupants of the plane, with no survivors reported from the wreckage.

Findings

Investigations into the accident determined that the primary factor was a mechanical failure involving the propulsion system. Specifically, one engine ceased functioning shortly after takeoff, while the remaining engine suffered a partial loss of power, making it impossible to maintain flight.

Probable cause

The accident was caused by the simultaneous failure of one engine and a significant power reduction in the second engine during the climb.
