Unfallbericht:
Weather at Huntsville was below minima, so the flight was diverted to Houston Intercontinental Airport. The runway 08 ILS approach was abandoned due to intermittent operation of the aircraft ILS localizer receiver instruments. The crew then tried an NDB approach with Houston TRICON monitoring on surveillance radar. The DC-3 continued descent below minimum descent altitude until the left wing collided with a 23 m high power line tower, located 3 km short of the runway. About 5 m of wing was torn off; the aircraft continued 195 m before striking the ground in a 30-degree nose down and inverted attitude.
PROBABLE CAUSE:
pilot in command - improper in-flight decisions or planning
pilot in command - improper ifr operation
FACTORS:
weather - low ceiling
weather - fog
terrain - high obstructions
miscellaneous acts,conditions - pilot fatigue
