The Douglas DC-3 OH-LCC was scheduled to take-off at 7:00, but take-off preparations were late and the plane was able to take off at 7:16. The co-pilot requested free flying altitude from the air traffic control, which was permitted. This allowed Flight 311 to fly at any altitude above the minimum flight altitude for the Kruununkylä-Vaasa route which was 450 meters (1500 ft). The pilots did not follow these regulations as they had flown the last 40 kilometers below 100 meters.
Shortly after the flight's last radio contact with the air traffic control, in which the pilots confirmed the weather report and said that they will be at Seppä lighthouse in a few minutes, the flight was starting to prepare for landing below 50 meters. Next, the plane turned abruptly to the left. This slowed the plane and distrupted air flow significantly. The pilots tried to correct the situation by applying full throttle. This did not help and the plane went into a spin. The last thing seen by eye-witnesses on ground was that the pilots had turned landing lights on before the plane crashed into woods at 07:40:30 at a 70-degree angle.
The first people arrived to the scene after 10 minutes could not try to rescue anyone from the wreck as it was burning in 15 meter long flames and was completely destroyed.

Date of Crash: 01/03/1961
Aircraft Model: Douglas C-47A-30-DK (DC-3C)
Military or Civilian: Civilian
Cause of Crash:
PROBABLE CAUSE: "The probable cause of the accident was the wrong execution of a left turn at low altitude at night, as a result of which the aircraft stalled, lost its manoeuvrability and went into a spin. Contributing factor: As a consequence of having had alcoholic drinks and insufficient sleep the night before the, the pilot was not considered to be in a satisfactory mental and physical condition to undertake the flight. For the same reason, the co-pilot should not have been allowed to start on the flight in question."
