Investigator assessment
Analysis narrative
At 0144 the plt was issued an approach clearance to the dublin airport & cleared to maintain 3,000 ft msl or above until established on the instrument approach. At 0148 the clearance was amended to a cruise clearance of 3,000 ft or above (the airport does not have an instrument approach). The pilot then reported he was still in the clouds at 2,100 ft msl (605 ft agl). Witnesses reported that the airplane was heard descending at 'maximum power' when it struck a telephone pole. The pilot operated a 24-hour 7-days-a-week veterinarian clinic in spring, texas, and had worked a consecutive 3 day shift from 0800 to 2400 before departing the clinic for the departure airport.
