L-410 prototype crash near Nedakonice

4 fatalities • Uherské Hradiště-Kunovice, Czech Republic • Flight

A prototype Let L-410 crashed during a local test flight, resulting in the deaths of all four crew members on board.

What happened

A flight involving an L-410 prototype departed from d’Uherské Hradiště-Kunovice Airport to conduct a routine local test mission. The aircraft was operated by a crew consisting of two pilots and two technicians. During the cruise phase at a low altitude, the pilot-in-command lost control of the aircraft. This loss of control led to a rapid descent into a field situated in Nedakonice, a short distance from the departure airfield.

The impact resulted in the total destruction of the airframe. There were four fatalities and no survivors among the crew members.

Findings

Investigations into the accident determined that the structural failure was triggered by aggressive maneuvers. Specifically, it is believed that the tail section separated from the aircraft during flight as a direct result of severe control inputs applied to the rudder by the pilot.

Probable cause

The aircraft's tail assembly detached during flight due to intense rudder inputs performed by the pilot.
