Instead, understanding how an airplane turns requires understanding the lift force generated by its main wings, the downward lift force imposed by the
horizontal stabilizer and how the elevator is used to control them.
The FAA said the "erroneous inputs can potentially make the
horizontal stabilizers repeatedly pitch the nose of the airplane downward, making the aircraft difficult to control."
The left and right
horizontal stabilizers were located about 850 feet and 790 feet, respectively, from the main wreckage.
He immediately saw the problem: the control cable that connects the
horizontal stabilizer to the components in the front of the aircraft was frayed almost to the point of breaking.
Boeing has bought a new building in the Salt Lake City suburb of West Jordan to focus on fabrication of composite
horizontal stabilizer components for the 787-9 Dreamliner.
Hamilton Sundstrand and its subsidiaries supply a wide range of systems for this multipurpose new-generation airlifter, including the A400M's Auxiliary Power Unit, Secondary Electrical Power Distribution Center, Ram Air Turbine emergency power system, Trimmable
Horizontal Stabilizer Actuator, Throttle Control Assembly, Cockpit and Load Master Workstation Lighting, and an eight-bladed 17.5-foot diameter Propeller System, the largest all-composite propeller in production.
Under the terms of the agreement Hamilton Sundstrand will provide the same suite of systems it is currently providing for the A320 family of aircraft, including the electric power generation system, cabin pressure control system, emergency ram air turbine, auxiliary power unit, cabin signage lighting, flight and cockpit controls and door and
horizontal stabilizer actuation.
We then positioned the man-lift under the starboard
horizontal stabilizer with two personnel onboard: an AT3 holding the p-static sprayer wand and an ATAN driving the man-lift.
Boeing, Alenia Aeronautica, Rolls-Royce Boeing has confirmed a fresh delay to its 787 programme, citing compounded issues with workmanship problems with the aircraft's Alenia Aeronautica-built
horizontal stabilizer and its Rolls-Royce Trent 1000 engines.
Recently, a series of problems involving F-15 jets have been reported, with part of the engine of one falling into the Sea of Japan off Hokkaido and part of the
horizontal stabilizer of another dropping off at an aviation festival in Fukuoka Prefecture.
