Analysis

The airplane was destroyed on impact with trees, power lines, and terrain during takeoff. The pilot, student pilot rated passenger, and two other passengers were fatally injured. The pilot of the airplane that departed before the accident airplane stated that on his takeoff he "bent forward as his window partially fogged. He used his landing light to align with the runway centerline and maintain runway heading until he gained visual cues." A witness stated, "I ... saw the second plane taking off in the same direction. I noted that it was not very high off the ground. I saw its red and green lights but its headlight or landing light was not visible. ... A few seconds later, I heard what sounded like a crash or an explosion and the lights went out in the house." Another witness stated that "there was a flash of light and he looked out to see a fire in front of his house and in the street. He said that there were tiny fires through out the area and the fires went out quickly. He said it was a cloudy night and very dark. ... He said the airplane noise was coming from a different direction then he usually hears." The pilot stated that he "saw one side of runway lights on the way in and did not notice runway lights on takeoff." An on-scene investigation found no anomalies. Continuity was established to the flight controls. Engine control continuity was established. The engine produced a thumb compression at all cylinders. The left magneto produced spark at all leads. Fuel was found in the fuel selector valve. The propeller blades exhibited chordwise abrasions. A power line was found with a missing section. The operator's safety recommendation stated, "The pilot of the other aircraft that departed just prior said 'We should have departed to the south. The wind was calm. But there are more lights, from a beacon, buildings, few houses etc. Simply more to reference ... the [horizon.']" The weather was: Wind calm; visibility 10 statute miles; sky condition clear; temperature -20 degrees C; dew point -21 degrees C; altimeter 30.11 in Hg.

Factual Information

HISTORY OF FLIGHT On February 14, 2001, about 2102 central standard time, a Piper PA-28R-201(Arrow), N120CC, piloted by a commercial pilot, was destroyed on impact with trees, power lines, and terrain near Webb Lake, Wisconsin during takeoff from runway 4 at Voyager Village Airstrip Airport (Y05), near Webster, Wisconsin. The personal flight was operating under 14 CFR Part 91. Dark night and visual meteorological conditions prevailed at the time of the accident. No flight plan was on file. The pilot, student pilot rated passenger, and two other passengers were fatally injured. The flight was originating at the time of the accident and was destined for Lake Elmo Airport (21D), near Saint Paul, Minnesota. Two airplanes landed at Y05 for dinner at the restaurant near the airport. After dinner, the flights departed for their respective destinations. The pilot of the airplane that departed before the accident airplane stated that on his takeoff he "bent forward as his window partially fogged. He used his landing light to align with the runway centerline and maintain runway heading until he gained visual cues. He heard the instructor pilot in the Arrow announce that the Arrow was departing runway 4. He tried calling the Arrow with no response." A witness stated: A minute or two later, I heard another plane. I again went to the window and saw the second plane taking off in the same direction. I noted that it was not very high off the ground. I saw its red and green lights but its headlight or landing light was not visible. The sound of the engine seemed normal but not as loud as the first plane's. I again sat down in my chair to resume watching TV. A few seconds later, I heard what sounded like a crash or an explosion and the lights went out in the house. Another witness stated in an interview: ...The nine o'clock news just started. He said he lost electrical power at his house about 10 minutes after 9. He stated the airport is about 400 yards from his house. He said the airplane sounded like it was working hard to make altitude. He stated that he heard two booms and then lost his lights. He said that there was a flash of light and he looked out to see a fire in front of his house and in the street. He said that there were tiny fires through out the area and the fires went out quickly. He said it was a cloudy night and very dark. ... He said the airplane noise was coming from a different direction then he usually hears. The pilot of the airplane that departed before the accident airplane stated that he "saw one side of runway lights on the way in and did not notice runway lights on takeoff." PERSONNEL INFORMATION The pilot was an instrument rated commercial pilot and he held a certified flight instructors certificate. He held a First Class Medical Certificate, dated September 29, 1998.

The student pilot rated passenger held a Third Class Medical Certificate and Student Pilot Certificate dated April 14, 2000. The pilot listed that he had Lasik eye surgical treatment on that application for that medical certificate. A record of flight time was found on-scene. That record listed 53.1 hours of total time, 4.4 hours of night time, and 15.1 hours of cross country time. AIRCRAFT INFORMATION The airplane was a Piper PA-28R-201, serial number 28R-7737057. The airplane logbook's last recorded annual inspection was dated January 16, 2001. That record listed the airplane's total time and its tachometer reading as 6,517.0 hours. METEOROLOGICAL INFORMATION At 2103, the Rice Lake Regional - Carl's Field Airport, near Rice Lake, Wisconsin, weather was: Wind calm; visibility 10 statute miles; sky condition clear; temperature -20 degrees C; dew point -21 degrees C; altimeter 30.11 inches of mercury. WRECKAGE AND IMPACT INFORMATION The airplane came to rest in a wooded area east of Long Lake Road at latitude 45 degrees 58.399 minutes N, and longitude 92 degrees 8.144 minutes W. About a nine foot section of the outboard right wing was found detached from the airplane approximately 300 yards southwest of the main wreckage resting at latitude 45 degrees 58.375 minutes N and longitude 92 degrees 8.224 minutes W in a wooded area west of Long Lake Road. Broken tree branches were found resting on the ground near that outboard section of right wing. The outboard section of the right stabilizer was found approximately 275 feet southwest of the main wreckage resting in that wooded area west of Long Lake Road.(See appended wreckage diagram.) The airplane fuselage was found inverted. The engine was found resting on the retained inboard section of right wing. The cabin door was found detached. The left and right fuel tanks were found deformed, discolored, and covered with a soot like substance.
