Atlantic Southeast Airlines Flight 2311 was a regularly scheduled commuter flight from Hartsfield-Jackson Atlanta International Airport to Brunswick Golden Isles Airport which suffered an uncontrolled collision with terrain during landing approach just north of Brunswick, on April 5, 1991. The aircraft was an Embraer 120RT Brasilia, registered N270AS. A few minutes before the aircraft impacted the ground, controllers at Glynco Jetport cleared flight 2311 for a visual approach to runway 07 at the airport. Witnesses reported that as the airplane approached the airport, it suddenly turned or rolled to the left until the wings were perpendicular to the ground. The airplane then fell in a nose-down attitude and disappeared out of sight behind the trees.〔http://www.airdisaster.com/reports/ntsb/AAR92-03.pdf〕 Four years later, another Embraer Brasilia of ASA crashed in the Georgia countryside, with 9 fatalities. ==Flight history== The aircraft involved in the accident was an Embraer EMB-120 Brasilia, manufactured on November 30, 1990. It was equipped with two Pratt & Whitney PW-118 engines and Hamilton Standard 14RF-9 propellers. The airplane received its U.S. standard airworthiness certificate on December 20, 1990. The aircraft had accumulated about 816 flying hours prior to the accident. Only one deferred maintenance item was noted in the maintenance logs. This was for fuel leaking from the auxiliary power unit cowling. The circuit breaker for the APU had been pulled while spare parts could be made available to fix the cowling. Captain Mark Friedline, age 34, had been hired by Atlantic Southeast Airlines in May 1981. He was fully qualified to fly three different commercial aircraft including the EMB-120. It was estimated that at the time of the accident, he had accumulated about 11,724 total flying hours, of which 5,720 hours were in the EMB-120. He had been involved in the development of the EMB-120, and its introduction to service in the United States, and was trained to fly the aircraft by the manufacturer. An inspector described his knowledge of aircraft systems "extensive", and his pilot techniques as "excellent". First Officer Hank Johnston, age 36, was hired by Atlantic Southeast Airlines in June 1988. He was a qualified flight instructor. Because more than 6 months had passed, since he had undergone an FAA medical inspection and he was issued with a first-class certificate, it automatically reverted to a second class certificate. A second class certification was adequate for his duties as a first officer. At the time of the accident, it was estimated that he had accumulated about 3,925 total flying hours, of which 2,795 hours were in the EMB-120. Flight Attendant Cindy Crabtree, age 30, was hired by Atlantic Southeast Airlines in 1986. 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「Atlantic Southeast Airlines Flight 2311」の詳細全文を読む スポンサード リンク
