| 摘要： | On December 17, 2000, about 1821 central standard time, a Beech BE-23, N2324J, impacted hilly, wooded terrain en route from Spirit of St. Louis Airport (SUS), Chesterfield, Missouri, to Tulsa, Oklahoma.1 The commercial-rated pilot, the sole occupant of the airplane, was killed, and the airplane was destroyed. Radar data indicate that about 1 hour after its departure from SUS, the airplanes heading and altitude became erratic. Between 1809 and 1821, the airplane descended from 8,500 feet mean sea level (msl) to 2,500 feet msl, and its flightpath was a series of irregular descending turns in an easterly direction. The last radar return was about 0.5 mile from the accident site. Visual meteorological conditions prevailed, and no flight plan was filed for the 14 'Code of Federal Regulations' (CFR) Part 91 flight. The National Transportation Safety Board determined that the probable cause of this accident was, in part, 'the pilots incapacitation due to carbon monoxide (CO) and a fractured muffler'. Postaccident examination of the airplanes's muffler at the Safety Board's materials laboratory revealed oxidation that penetrated the wall of the muffler shroud and extended around at least 20 percent of the muffler's circumference. The metallurgical report stated that the oxidized areas of the fracture appeared black, which was consistent with a preexisting fracture that was exposed to the environment for an extended period of time. |
