Category: Accident
A Li-2 aircraft experienced a critical incident during a takeoff clearance at Batagay Airport in -48øC conditions. The propeller oil froze, causing blades to become viscous and impede movement, leading to both engines overspeeding during the initial climb. The pilot attempted an emergency landing, resulting in a crash-landing on the embankment of the Batagay river.A Li-2 aircraft experienced a critical incident during a takeoff clearance at Batagay Airport in -48øC conditions.

Description
The Li-2 waited for take-off clearance at Batagay Airport for 20 minutes in -48′ C weather conditions. Since the flight engineer did not take measures to recycle the propeller pitch during that time, the propeller oil got viscous and the blades ‘froze’ in a position of 20 resp. 30 degrees. As a consequence both engines oversped during the initial climb. The pilot attempted an emergency landing but the aircraft crash-landed on the embankment of the river Batagay about 1 km from the runway, sustaining serious damage to landing gear, lower fuselage, wings and engines.
