Cessna 208B Caravan, Alliance, Neb., Feb. 8, 2007–The Caravan pilot’s descent below minimum descent altitude on a nonprecision approach caused this crash, according to the NTSB. A contributing factor was a low ceiling (reported weather was 1.25 miles visibility and a 200-foot overcast in mist). The cargo flight was dispatched to an airport with a precision instrument approach but the pilot flew to his usual airport, which had a VOR and an NDB approach (out of service). The instruments were nevertheless set for the NDB approach. The Suburban Air Freight Caravan hit a pole and a building on approach, and the sole-occupant pilot was seriously injured. He told investigators that he did not remember the accident
