CHI08FA039

The airplane's recorded airspeed indicated that the airplane slowed on final approach and subsequently encountered a recorded stall/spin condition during go-around from runway 12. A post impact ground fire and explosion occurred. The recorded winds at the airport were 190 degrees at 15 knots, gusting to 22 knots. On-scene and follow-up examinations of the wreckage and recorded data from the airplane's recoverable data module revealed no airplane or engine pre-impact anomalies. The maximum demonstrated crosswind component for the aircraft was 20 knots. Subsequent to the accident a remark was entered to the airport's master record. The remark advised pilots landing on runway 12 to be alert for turbulence and possible windshear when winds are out of the south.

History of flight

On November 25, 2007, about 1455 central standard time, a Cirrus Design Corp. SR22, N482SR, was destroyed on impact with terrain during landing on runway 12 (4,254 feet by 72 feet, dry asphalt) at the Faribault Municipal Airport (FBL), near Faribault, Minnesota. A post impact fire occurred. The personal flight was operating under 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed in the area at the time of the accident. No flight plan was on file. The private pilot and three passengers sustained fatal injuries. The flight originated from the Aberdeen Regional Airport (ABR), near Aberdeen, South Dakota, about 1300, and was destined for FBL.

About 1300, a witness, who was a lineman at ABR, saw the pilot and three passengers board N482SR and saw the airplane depart from ABR.

About 1300, a witness, who was a certified flight instructor (CFI) and lineman at the fixed base operator at FBL, saw a Cirrus SR22, N633CD, attempt a landing and saw it go-around. About 1440, the CFI was monitoring the Unicom frequency at FBL when the pilot of N482SR advised him of his intentions to land and refuel. The CFI stated that he saw N482SR on short final and saw the airplane go-around. About eight minutes later he saw the airplane over runway 12 about 40 feet above the ground in level flight heading towards his location. He reported that about four seconds later the airplane rolled left, and impacted terrain in an inverted attitude. The CFI indicated that the airplane impacted terrain left wing down, it cartwheeled, and then the post impact fire and explosion occurred.

Personnel information

The pilot held a Federal Aviation Administration (FAA) private pilot certificate with an airplane single-engine land and instrument rating. He had been issued a FAA third-class medical certificate on July 25, 2007, through an Aviation Medical Examiner Assisted Special Issuance for obstructive sleep apnea with the limitation that it was not valid for any class after July 31, 2008. The pilot was treated for his sleep apnea with a continuous positive airway pressure (CPAP) device that recorded its operational data. Data from that device revealed that the pilot had used it for at least 4 hours on each of the three nights preceding the accident.

According to a representative from the University of North Dakota (UND), the pilot completed the initial transition-training course for new Cirrus owners conducted by UND in September 2006. He completed the turbo difference course in December 2006. He completed the recurrent training course in October 2007. The pilot reported to UND that he had accumulated 1,200 hours of total time and 175 hours of time in a SR22.

The pilot's logbook was found at the accident site. The logbook pages were charred and partially readable. The pilot's logbook showed an endorsement for a flight review dated November 6, 2007 and an endorsement for an instrument proficiency check dated November 8, 2007.

Aircraft information

N482SR, a Cirrus Design Corp. SR22, serial number 2760, was a four-place single engine low wing airplane powered by a six-cylinder, 310-horsepower, Teledyne Continental Motors (TCM) model IO-550-N (50) engine, with serial number 691380, that drove a three-bladed Hartzell constant speed propeller. The airplane's airworthiness certificate was issued on October 19, 2007.

A receipt showed that on November 10, 2007, a mechanic found that the airplane landing light's wiring was "unhooked." The wiring was reconnected and the landing light operation was "ops' checked good. According to the receipt the airplane's Hobbs meter read 41.5 hours and the airplane had accumulated 33.4 hours of total flight time at the time of that corrective action.

A fuel log from ABR showed that the airplane was last fueled there on November 8, 2007. The log showed that the airplane was serviced with 29 gallons of 100 low lead aviation gasoline.

The airplane was equipped with an Avidyne Entegra Primary Flight Display (PFD) that was designed to provided the functions of the attitude indicator, heading indicator, airspeed indicator, altimeter, vertical speed indicator, directional gyro, course deviation indicator, and altitude pre-select controller onto a single electronic display. The airplane was also equipped with an Avidyne FlightMax EX5000C Multi-Function Flight Display (MFD). The MFD was a 10.4-inch landscape-oriented display mounted in the instrument panel that was designed to provide supplemental display of situational and navigation information to the pilot. The MFD could display normal and emergency checklists as well as performance data and could display navigation data, such as groundspeed and track. The PFD and MFD communicated data through a serial bus. The airplane was equipped with a recoverable data module that recorded parameters of the data transmitted on the serial bus.

The airplane's flight manual indicated that the airplane's maximum demonstrated crosswind component was 20 knots.

Meteorological information

At 1456, the recorded weather at FBL was: Wind 190 degrees at 15 knots, gusting to 22 knots; visibility 10 statute miles; sky condition clear; temperature 8 degree C; dew point -4 C; altimeter 29.77 inches of mercury.

Airport information

The airport elevation at FBL was 1060 feet above mean sea level. The airport was located about three miles north west of Faribault. FBL was a non-towered airport with two runways, 12/30 and 2/20. Runway 12/30 was a 4,254 feet long and 72 feet wide asphalt runway. Runway 2/20 was a 2,025 feet long and 140 feet wide grass runway.

Flight recorders

The airplane was equipped with a recoverable data module manufactured by Aerosance Inc. The module was installed in the airplane's empennage. The unit was designed to record airplane performance, configuration data, and navigation data to include the flight's groundspeed and global positioning system track. The flight's data was stored on a compact flash card within the module.

Wreckage and impact information

The airplane was found inverted on about a 180-degree magnetic heading in a bean field northeast of the runway 12 taxiway about 330 feet northeast of the runway's centerline and about 2,000 feet from the approach end of the runway. The composite portions of airplane's empennage and wings were consumed by fire. The metal portions of the airplane's empennage and wings exhibited deformation, discoloring, and melting. The fuselage, up to the firewall, exhibited damage and charring consistent with a fire. A ground scar was observed starting about 48 feet west of the wreckage and led to the center of the wreckage on about an 80-degree magnetic heading. The shape of the scar's depression was consistent with the inverted shape of the left wing tip. A red navigation light lens was found near the ground scar. A propeller blade had separated from its hub and was found imbedded in a depression in the ground north of the ground scar about 27 feet from the center of the wreckage. The depression's shape was consistent with the shape of the spinner and engine cowling. A propeller blade was found resting within the depression. The third propeller blade that exhibited chordwise abrasions on its back was found about 180 feet from the center of the wreckage on about a 350-degree magnetic heading from the center of the wreckage. The airplane's recoverable data module was deformed, discolored, and was found about 84 feet north of the center of the wreckage. The top of the oxygen bottle was found about 309 feet from the center of the wreckage on about a 70-degree magnetic heading from the center of the wreckage. The airplane's parachute was found extended on the ground starting with its risers near the center of the wreckage and its topmost portion resting about 120-degrees magnetic and 105 feet from the center of the wreckage.
