From the Wikipedia article
The Il-14 crash near Penek was an aviation accident that occurred on the afternoon of Tuesday, 5 April 1977. An Il-14 passenger aircraft belonging to the West Siberian flight detachment (Aeroflot) was operating a flight to train three co-pilots for independent flying. The aircraft took off from Novosibirsk-Severny airport and was to return there, but about 30 minutes after departure it collided with the ground 91 kilometres from the departure airport. All 6 crew members on board were killed.
Chronology of events
On 5 April 1977, the crew of aircraft USSR-61675 was to perform a flight to train three co-pilots for independent flying under the aircraft commander training programme. The assignment included simulating the failure of one engine in various flight modes.
The weather forecast in the flight area was as follows: cloud cover 6-9 oktas, stratocumulus, fractostratus. Cloud tops at 3-4 kilometres. Snow. Visibility 4-6 kilometres. The aircraft took off at 14:30. At 14:53 the crew arrived in the aerobatic zone and began performing the exercises. At 15:19 the aircraft did not respond to a call. The aircraft collided with the ground at approximately 15:00. The crew was simulating a failure of the left engine in a left turn. To counter the yawing moment, the rudder was deflected by the crew to the right by 18-20 degrees, that is, to a position close to rudder overbalance. From the onset of overbalance the rudder spontaneously and rapidly moved to the right to its maximum deflection, which was aided by a sideslip onto the left wing. The aircraft lost controllability and went into a rapid uncontrolled descent. The collision with the ground occurred with the left wing panel, with a sideslip to the right, at a high vertical speed and a low forward speed. The burning aircraft was found at a distance of 91 kilometres from Tolmachevo airport on an azimuth of 297 degrees. The rudder was deflected fully to the right. The aircraft fell at an angle of 45-60 degrees with a pitch angle of 50-60 degrees and a left bank of 40 degrees. All 6 crew members on board were killed.
