Circumstances:
The aircraft took off from Olenek Airport at 1651LT. While climbing to a height of 100-120 meters, the engine lost power. The captain decided to return for an emergency landing and initiated a turn to the left when the airplane stalled and crashed, one minute after takeoff. The aircraft was destroyed and all five occupants were injured.
Probable cause:
It was determined that the loss of engine power was the consequence of the malfunction of the spark plugs due to an excessive accumulation of tetraethyl plumb.
