ATC implicated in fatal King Air accident

The NTSB determined the probable cause of a January 2000 King Air C90 fatal accident was the failure of the pilot to follow his approach clearance, and his subsequent descent into unprotected airspace, which resulted in a collision with the guy wire of a 460-ft microwave antenna. Factors in the accident were the air traffic controller’s failure to verify that the approach for which he cleared the pilot was in service, and the clouds that restricted the prominence of the antenna.
