(-23) On July 2, 2006, about 0925 central daylight time, a single-engine Cessna 180K tailwheel-equipped airplane, N1SE, was substantially damaged when it impacted terrain following a collision with static transmission lines while on takeoff from a residential street, near Owasso, Oklahoma. The private pilot sustained fatal injuries and the passenger was seriously injured. The airplane was registered to an individual and was operated by the pilot. Visual meteorological conditions prevailed and a flight plan was not filed for the 14 code of federal regulations part 91 personal flight. The local flight had originated from a private airstrip about 0915. A witness was working in the backyard of a residence when he observed the accident airplane flying "real low" over the trees in a southerly direction. As the witness watched, the airplane descended out of view behind a house and garage that was located several doors east of where he was standing. The witness stated, "the engine sounded fine, but I heard a bang and went around to the front yard to investigate." From the front yard he observed a street sign at the north end of 181st street bent over. The witness then went into the house, got his sister and together they drove east along 79th steet to find the airplane. As they approached the intersection of 79th and 181st streets, they observed the airplane on the ground back taxiing to the north end of 181st street before it turned 180-degrees back towards the south. According to the two witnesses, once the airplane completed its 180-degree turn, it started a takeoff roll southbound along 181st street. Approximately 380 feet along its takeoff roll, the airplane's left wing impacted the street sign for the second time before continuing southbound. The witnesses added that as the airplane lifted off the road it began to drift to the east below two transmission lines that ran parallel to the road. The witnesses further reported that as the airplane climbed, the left wing came up under, and slid along, the lower transmission line before the airplane rolled across the wires and impacted the ground in a near vertical descent. The pilot and passenger were reported to have departed from a private airstrip with the intended destination of gundy's airport (O38), which was located about two and a half miles southwest of their departure point. The street on which they landed (181st street) was located approximately two miles along their route and about 3,090 feet directly east of O38. Both O38'S runway and 181st street ran north and south with their south ends terminating at 76th street. Runway 17, at O38, was a 2,600 feet long by 26 feet wide asphalt runway. 181st street was constructed of asphalt and was approximately 1,600 feet long and 22 feet wide. Both runway 17 and 181st street had orange windsocks east of their locations. The transmission lines were located on the east side and parallel to 181st street. The lines began about 900 feet from the north end of the 181st street and continued south to 76th street. At 0953, the automated weather observing system at the tulsa international airport (tul) near tulsa, Oklahoma, located approximately 7 nautical miles southwest from the site of the accident, reported wind from 190 degrees at 8 knots, 10 statute miles visibility, few clouds at 25,000 feet, temperature 84 degrees, dew point 66 degrees, and a barometric pressure setting of 30.12 inches of mercury.
