Unfallbericht:
The aircraft struck cottages, located 4890 feet short of runway 02, and crashed. The aircraft was on a non precision instrument approach.
The Convair was originally manufactured as a Convair CV-440 and converted to a Convair 580. The plane had flown 8406 hours since the conversion in September 1967.


PROBABLE CAUSE: "The captain's intentional descent below the prescribed minimum descent altitude under adverse weather conditions without adequate forward visibility or the crew's sighting of the runway environment. The captain disregarded advisories from his first officer that minimum descent altitude had been reached and that the airplane was continuing to descend at a normal descent rate and airspeed. The Board was unable to determine what motivated the captain to disregard prescribed operating procedures and altitude restrictions and finds it difficult to reconcile the actions he exhibited during the conduct of this flight."
