Narrative:
The Cubana aircraft, on a flight from Miami to Havana, was in, or had just performed, a gentle left bank leveling out on the Havana heading of 197 degrees when it collided with a US Navy Beech SNB-1 Kansan (39939) at an altitude of 4000 feet. The Navy plane was on an instrument training flight out of Key West-NAS. The SNB crashed into the water just west of the Naval Station, but the DC-4 continued for some distance before commencing a left bank which became progressively steeper until the aircraft assumed a nose-down attitude, crashing into the ocean 1,7 miles from the point of the collision.

PROBABLE CAUSE: "The failure of the crews of both aircraft to maintain sufficient vigilance under VFR conditions to prevent a collision."
