Category: Accident
An L-410 aircraft experienced a catastrophic crash during takeoff, resulting in the loss of all 14 passengers. The engine failure immediately halted the takeoff, leading to a stall and subsequent sinking into the Aldan River. The lack of proper undercarriage retraction contributed to the aircraft’s inability to climb and maintain control.An L-410 aircraft experienced a catastrophic crash during takeoff, resulting in the loss of all 14 passengers.

Description
The Let L-410 was accelerating for takeoff when the no.1 engine automatically shut down just after passing V1. The flight crew feathered the prop but failed to retract the undercarriage. The aircraft was not able to climb out and stalled. It came down in the Aldan river 270 metres from the banks and sank. All 14 on board drowned as they were not able to open the doors. Conclusion: The cause of the crash was the loss of controllability of the aircraft during continued take-off due to the crews failure to comply with the climb height requirements at the recommended speed of 170 km/h due to changes in the initial flight path towards obstructions at the moment the left engine was shut down.
