From the Wikipedia article
The Let L-200 crash in Bryansk was an aviation accident involving a Let L-200D Morava passenger aircraft of the company Aeroflot, which occurred on Saturday 4 September 1965 on the outskirts of Bryansk; 1 person was killed.
Crash
On 2 September the aircraft operated passenger flight F-49 from Moscow (Bykovo Airport) to Gomel with an intermediate stop in Bryansk; it was flown by G.K. Kudryavtsev. The next day the pilot began preparing to operate the return flight F-50 to Moscow, when it turned out that if button No. 2 was pressed, vibration appeared in the right engine and the rotational speed dropped to 400 revolutions per minute. The detected malfunction was reported to the dispatcher and to the head of the section of the aviation engineering service of the Gomel Joint Aviation Detachment (IAO GOAO), after which the departure of aircraft 34469 was cancelled. On the morning of the following day (4 September) at 08:30 MSK, pilot Kudryavtsev reported to the dispatcher that, together with an aviation technician, he had rectified the engine malfunction by cleaning the magneto contacts, and he received clearance for departure. At 09:28 MSK flight F-50, with two passengers and the pilot on board, took off from Gomel Airport.
At 10:30 MSK, flying at an altitude of 300 metres, flight F-50 entered the Bryansk Airport zone, and the pilot requested landing conditions. However, a minute to a minute and a half later Kudryavtsev reported that the aircraft had "interruptions in the right engine", and at 10:33 reported that "the right engine is feathered". When at 10:34 the controller asked where the aircraft was, the pilot replied: I am on the outskirts of the city. At 10:36 the controller asked about the flight conditions, to which he received the reply: speed 160, altitude 170. At 10:37 the pilot reported following a heading of 110°, after which he made no further contact.
It was established that, having passed the outer marker radio beacon, pilot Kudryavtsev began a left turn, that is, towards the operating engine, with the flaps extended to 15°. During this manoeuvre height was lost, so that, having turned to 320°, the airliner found itself at a dangerously low altitude. Trying to correct the situation, the pilot through his actions caused the speed to drop; as a result the aircraft entered a spin and struck the roof of house 52 on Plekhanov Street, 6 kilometres from the airport, with its left wing, demolishing its veranda. Having turned through 180°, the machine fell onto the street, the nose section of the fuselage was destroyed, and everyone on board was seriously injured. Two hours after the accident pilot Kudryavtsev died in hospital from his injuries, becoming the only victim of the crash.
Investigation and cause
Causes
According to the commission's conclusion, one of the main causes of the accident was that the aircraft had been cleared for flight although its right engine had run 81 hours beyond its established service life. Another main cause was the clearance of the aircraft for flight at Gomel Airport, despite the fact that no technical inspection of it had been carried out and the causes of the vibration and the drop in engine rpm had not been identified. The State Scientific Research Institute of Civil Aviation was unable to establish what caused these malfunctions. It could not be established why the right engine shut down during the flight. An accidental shutdown could only have occurred because the altitude corrector lever was in the "rich" position. However, all the other levers and control buttons of this engine were in a position consistent with the pilot having deliberately shut down the engine.
Another cause of the crash was named as pilot Kudryavtsev's limited flying experience on a twin-engine aircraft (23 hours of solo flight time on the Let L-200), especially in single-engine flight conditions. Owing to insufficient practice, the pilot may have hastily taken the mistaken decision to shut down the engine. As a result, during the landing approach the machine lost forward speed and fell into a spin.
