Unfallbericht:
A few seconds after taking off from runway 05, the Electra struck a flock of starlings. A number of these birds were ingested in engine no.1, 2 and 4. Engine no. 1 was shut down and the prop feathered. Shortly after that the no. 2 and 4 engines experienced a substantial momentary loss of power. This caused the plane to yaw to the left and decelerate to stall speed. The left wing then dropped, the nose pitched up and the L-188 rolled left into a spin and fell almost vertically into the water.

Probable Cause:

PROBABLE CAUSE: "The unique and critical sequence of the loss and recovery of engine power following bird ingestion, resulting in loss of airspeed and control during takeoff. "
