United Airlines Flight 227 (N7030U), a scheduled passenger flight from LaGuardia Airport New York City to San Francisco International Airport, California, crashed short of the runway while attempting a scheduled landing at Salt Lake City International Airport, Utah on November 11, 1965. ==Accident details== Flight 227, operated by a Boeing 727-22, registration departed LaGuardia Airport at 0835 Mountain Standard Time (1035 EST) for San Francisco, California, with scheduled stops in Cleveland, Chicago, Denver, and Salt Lake City. The flight to Denver was routine. In Denver a new flight crew took control of the plane: Captain Gale C. Kehmeier, First Officer Philip E. Spicer, and Second Officer Ronald R. Christensen. The flight took off from Denver at 1654 MST. During the flight, the First Officer was flying the aircraft under the direction of the Captain. At 1735 the plane was cleared to descend to 16,000 feet by the Salt Lake City Air Route Traffic Control Center. At 1747, now under the direction of terminal control, the plane was cleared to approach. At 1748, in response to the controller's request for the plane's altitude, the pilot replied "Okay we've slowed to two fifty (knots) and we're at ten (10,000 feet) we have the runway in sight now, we'll cancel and standby with your for traffic." The plane began to descend, but its rate of descent was approximately 2,300 feet per minute, nearly three times the recommended rate of descent. At approximately 1749:30, the plane passed the outer marker 5.7 miles from the runway threshold at approximately 8,200 feet, over 2,000 feet above the normal glideslope. At approximately 1751, one minute prior to impact, the plane passed 6,300 feet; it was still 1,300 feet above the normal glide slope and still descending at 2,300 feet per minute. Around this time the first officer reached toward to advance the thrust levers to increase thrust, but the captain brushed his hand aside and said "Not yet." At 30 seconds prior to impact the plane was 1,000 feet above and 1.25 miles from the runway. The captain indicated in post-crash interviews that at this point he moved the thrust levers to the takeoff power position, but the engines failed to respond properly. However, both the testimonies of the other members of the flight crew and the data from the flight data recorder indicate that the attempt to add power occurred only about 10 seconds before impact. At 1752 the plane struck the ground 335 feet short of the runway. The aircraft slid 2,838 feet before coming to a stop. The separation of the landing gear and the No. 1 engine was the result of impact loading in excess of their design structural strength. The failure of the landing gear caused the rupture of fuel lines in the fuselage. The resulting fire, rather than the impact of the crash, accounted for all 43 fatalities. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「United Airlines Flight 227」の詳細全文を読む スポンサード リンク
