HISTORY OF FLIGHT
On November 1, 2010, about 1530 central daylight time, a Luscombe 8A, N71823, sustained substantial damage when it impacted the ground after takeoff from runway 11 (3,800 feet by 100 feet, concrete), at the Schaumburg Regional Airport, Schaumburg, Illinois. The pilot, who was the sole occupant, was fatally injured. The airplane was registered to and operated by the pilot under the provisions of 14 Code of Federal Regulations, Part 91 as a personal flight. Visual flight rules (VFR) conditions prevailed for the flight, which was not operated on a flight plan. The flight was originating at the time of the accident and was en route to the Sylvania Airport, Sturtevant, Wisconsin.

A commercial pilot who was at the airport was a witness to the accident. He reported that the initial climb after takeoff appeared to be at a normal pitch angle and when the airplane reached about 150 feet above ground level (agl), the sound of the engine ceased. The airplane “hung there” and then stalled. The left wing dropped and the airplane made about one-half of a revolution before it impacted the ground. The witness stated that he could see that the propeller was turning during the accident sequence. He also reported that prior to the accident flight the pilot fueled the airplane using a red fuel can and that the pilot may have had trouble getting the airplane’s engine started; however, the witness stated that the engine sounded normal during its taxi and subsequent takeoff until the point where the engine sounds ceased.

PERSONNEL INFORMATION
The pilot held a commercial pilot certificate with single-engine land, single-engine sea, glider, and instrument airplane ratings. He also held a flight instructor certificate with a rating for single engine airplanes. The pilot’s most recent second class airman medical certificate was issued on September 11, 2007. The pilot reported having 1,100 hours of flight experience on his application for that medical certificate.

AIRCRAFT INFORMATION
The airplane was a 1946 Luscombe model 8A, serial number 3250. It was a 2 place airplane with tailwheel type landing gear and side-by-side seating. It had a strut braced high-wing. The wing had aluminum covering, and the fuselage was of predominately aluminum construction. The airplane was powered by a Continental A-65-8 engine rated to produce 65 horsepower. The airplane’s most recent annual inspection was completed on September 16, 2010.

METEOROLOGICAL INFORMATION
At 1552, the recorded weather conditions at the Dupage Airport, about 8 miles southwest of the accident site, were: Wind 280 degrees at 6 knots; 10 statute miles visibility; broken clouds at 8,000 feet agl; temperature 22 degrees Celsius; dew point 6 degrees Celsius.

WRECKAGE AND IMPACT INFORMATION
The airplane impacted the ground about 20 feet to the side of the runway. The aft fuselage was partially separated from the forward fuselage at the aft cabin. All of the airplane’s tail surfaces remained attached to the aft fuselage. The engine and forward fuselage were crushed rearward. The wings exhibited impact damage to their leading edges and the wings remained attached to the upper cabin of the fuselage. The upper cabin section of the airplane had separated from the remainder of the fuselage. The wing struts remained attached at all points and the main landing gear remained attached to the fuselage. Examination of the airplane’s control system revealed no preimpact anomalies.

Examination of the cockpit controls for the engine revealed that the magneto switch was in the “Right” position and the key was bent, the carburetor heat was off, the throttle was full forward, and the engine primer was out.

Examination of the airplane’s engine confirmed crankshaft rotation, valve train continuity, and magneto operation. Compression was evident on 3 cylinders during initial examination of the engine. Compression on the fourth cylinder was evident after “staking” the valves. All spark plugs exhibited sooting, consistent with a rich mixture. Fuel was present in the carburetor and the fuel strainer was free of obstruction. No preimpact anomalies were found with respect to the engine.

MEDICAL AND PATHOLOGICAL INFORMATION
An autopsy was performed on the pilot on November 2, 2010, by the Cook County Medical Examiner’s Office. The autopsy findings included "multiple injuries," and the report listed the specific injuries. The cause of death was attributed to these injuries.

Forensic toxicology was performed on specimens from the pilot by the FAA Bioaeronautical Sciences Research Laboratory, Oklahoma City, Oklahoma. The toxicology report listed negative findings for all tests performed.

ADDITIONAL INFORMATION
Referencing Federal Aviation Administration Special Airworthiness Information Bulletin CE-09-35, the temperature and dew point at the time of the accident were conducive for the formation of carburetor icing.

The accident airplane was a standard category airplane but its specifications allowed it to be operated as a light sport airplane. When operated as a light sport airplane, the pilot is not required to possess a current airman medical certificate. Pilots are allowed to use their state driver’s license to establish medical fitness in-lieu of an actual airman medical certificate unless their most recent application for an airman medical certificate was denied.
