Cirrus Design CORP SR20 accident near Crystal Lake, Illinois, November 26, 2011

The NTSB's narrative final · quoted from the NTSB record

The noninstrument-rated pilot was conducting the accident flight under visual flight rules (VFR) without a flight plan. The pilot contacted the tower air traffic controller at the intended destination airport and inquired about landing. The controller informed him that the airport was currently under instrument flight rules (IFR). About 30 seconds later, the pilot informed the controller that he had inadvertently flown over the airport. The controller ultimately cleared the flight to land; however, the pilot decided not to land, informing the controller that he did not want to get delayed at the airport due to the weather. The pilot subsequently told the controller that the flight was “in and out of the clouds.” After asking the pilot if he was IFR qualified (and learning that the pilot was not), the controller transferred the flight to the local radar-equipped approach control facility for further assistance. That controller advised the pilot of several airports in the vicinity that were under VFR. After initially indicating that he would divert to one of those airports, the pilot told the controller that he did not want to “mess with the weather” and did not want to “get stuck in here,” and he declined to proceed to that airport. Radar data depicted that, shortly after the pilot’s radio transmission, the airplane entered a gentle right turn. About 90 seconds later, the right turn tightened abruptly, consistent with the airplane entering a steep spiral. The last 19 seconds of radar data depicted the airplane entering a climb of about 2,500 feet per minute (fpm) followed by an approximate 3,600-fpm descent. Witnesses reported hearing an airplane overhead, but they were not able to see it due to the cloud cover. They described the sound as similar to an airplane performing aerobatics. The witnesses subsequently observed the airplane below the clouds in a steep, nose-down attitude before it struck the ground. Based on reported weather conditions in the vicinity of the accident site, the flight encountered instrument meteorological conditions. A postaccident examination of the airplane did not reveal any anomalies consistent with a preimpact failure or malfunction.
