Narrative:
The Antonov An-2 suffered a runway excursion when it failed to lift off the runway during takeoff at the "May 1" collective farm near Zhuravskoye.
The aircraft came to rest in trees.
The cause of the accident with the An-2 RA-68161 aircraft was a drop in engine power during takeoff, which led to the need for a forced landing immediately after the aircraft took off, as a result of which a rolling out of the runway occurred with a subsequent collision with the trees of the forest belt.
The drop in engine power was due to the destruction of the exhaust manifold flame tubes, which led to a loss of engine power on takeoff due to the ingress of exhaust gases into the carburetor through an open choke.
The destruction of fragments of the exhaust manifold flame tubes occurred as a result of overheating of the material during operation.
Contributing factors are most likely to be:
- shortcomings in the technical operation of the aircraft: flight operations over a long period of time without taking into account the engine operating time and without obtaining the Airworthiness Certificate (without carrying out the work necessary to obtain it);
- lack of sufficient distance to safely end the takeoff.
