What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) This is a preliminary report. When the remainder of the relevant facts become known, an amended report will be filed. (-23 amendment) the pilot was IFR enroute from bozeman (kbzn), Montana to oakland (koak), California on September 16, 2006. He was cruising at 15,000 MSL. He was in and out of IMC. He noticed his left fuel cap was missing and asked for a lower altitude. Ice was progressively accumulating on the aircraft as he was descending to lower altitudes. Shortly after that his airspeed dropped to zero, the angle of attack indicator froze and he began to receive verbal warnings regarding his angle of attack and the aircraft's landing gear. At 8,000 feet the verbal warnings ceased and he was cleared to twin falls, Idaho (ktwf) airport. Fuel was now venting at a good rate from the left tank and he requested info for the nearest airport and was told about Rockford, Idaho. He then proceeded to land there. At 5 feet AGL the airplane suddenly pitched down and it struck the ground despite the pilot adding full power to arrest the altitude loss. The airplane then bounced and slid off the runway to the left. The airplane came to a stop with the left wing on the ground, the right wing up, sitting upright. The left main landing gear was collapsed; the right main landing gear was partially collapsed. The propeller had struck the ground with both tips slightly bent and the nose wheel in place. This is a final report.
