Die Boeing 737 der USAir befand sich auf einem Linienflug von Chicago nach Palm Beach mit einer planmäßigen Zwischenlandung in Pittsburgh. [23][24] USAir ceased using Flight 427 as a flight number. "Chuck" Emmett III, 38, who was hired in February 1987 by Piedmont Airlines (which merged into USAir in 1989). The aircraft had recorded approximately 18,800 hours of flight time before the crash. Peter Germano, 45, of Moorestown, N.J. who had worked for USAir since February 1981. [11]:153, Investigators later discovered that the recovered accident rudder power control unit was much more sensitive to bench tests than other new such units. Beautiful days have a way of changing.

September 1994 verunglückte eine Boeing 737-3B7 auf dem USAir-Flug 427 im Landeanflug auf Pittsburgh durch einen plötzlichen Vollausschlag des Seitenruders. [1]:292–295 The final report also included detailed responses to Boeing's arguments about the causes of the three accidents. AT 6.57 pm on 8 September 1994, the pilot and co-pilot of USAir flight 427 were swapping recipes for fruit drinks with one of the flight attendants. It's an investigation one man says affected him differently than any other. [1], Reading the control-yoke data from the FDR revealed that the pilots made a crucial error by pulling back on the yoke throughout the dive, with the stick shaker audible on the CVR from the onset of the dive. By Jeff Martinelli and Natalie Fiorilli. At the time of the crash, Flight 427 was the second-deadliest accident involving a Boeing 737 (all series); as of 2020, it now ranks as the ninth deadliest. You can help. The National Transportation Safety Board investigated the crash. All 127 passengers and five crew members were killed. [1][11] The FDR revealed that after the aircraft stalled, the plane and its occupants were subjected to a load as high as 4 g throughout the dive until impact with the ground in an 80-degree nose-down attitude at approximately 300 mph under significant sideslip. TWA Flight 427 was a regularly scheduled TWA passenger flight departing Lambert-St. Louis International Airport (STL) in Bridgeton, Missouri on November 22, 1994, operated using a McDonnell Douglas MD-82.

When they began to gather up the 132 bodies from USAir Flight 427 today, officials realized there were so many pieces that the grisly task would take days, perhaps weeks. However, two parameters recorded were crucial: the aircraft's heading and the pitch-control yoke position. [1]:96–100[19] Boeing agreed to redesign the rudder control system with a redundant backup and paid to retrofit the entire worldwide 737 fleet. At 19:02:57, the aircraft entered the wake turbulence of Delta 1083, and three sudden thumps, clicking sounds and a louder thump occurred, after which the 737 began to bank and roll to the left. The exact mechanism of the failure involved the servo valve, which remains dormant and cold for much of the flight at high altitude, seizing after being injected with hot hydraulic fluid that has been in continuous action throughout the plane. [13][11] It stated that the cause of the rudder reversal was more likely psychological and likened the event to a circumstance in which an automobile driver panics during an accident and accidentally presses on the gas pedal rather than the brake pedal. Here are some images taken from the video as a reminder.

Cellini, 37, thought of his wife, a USAir flight attendant who was supposed to work the next day. Boeing felt the latter more likely, while USAir and the pilots' union felt that the former was more likely. During the approach, Flight 427 encountered wake turbulence from Delta 1083, but the FAA determined "the wake vortex encounter alone would not have caused the continued heading change that occurred after 19:03:00. This raised the aircraft's angle of attack, removed all aileron authority, prevented recovery from the roll induced by the rudder and caused an aerodynamic stall. [11] Boeing's test pilots reenacted the dive in a simulator and in a test 737-300 by flying with the same parameters recorded by the accident FDR, and found that recovery from a fully deflected rudder at level flight, while at 190-knot crossover speed, was accomplished by turning the wheel to the opposite direction of the roll, and not pulling back on the yoke to regain aileron authority. [4] As a result, pilots were warned of and trained how to deal with insufficient aileron authority at an airspeed at or less than 190 knots (352 km/h), formerly the usual approach speed for a Boeing 737. [8] USAir had difficulty determining Flight 427's passenger list, facing confusion regarding five or six passengers. Unfallhergang.

The aircraft continued to roll while pitched nose-down at the ground. The jam left no trace of evidence after it occurred, and a Boeing engineer later found that a jam under this controlled condition could also lead to the slide moving in the opposite direction than that commanded.
