During the 1990s, a series of issues affecting the rudder of Boeing 737 passenger aircraft resulted in multiple incidents. In two separate accidents (United Airlines Flight 585 and USAir Flight 427), pilots lost control of their aircraft due to a sudden and unexpected rudder movement, and the resulting crashes killed everyone on board, 157 people in total.

Flight 585 was operated by a Boeing 737-291, registered as N999UA with serial number 22742. [2] It was manufactured in May 1982 for the original incarnation of Frontier Airlines, and was acquired by United Airlines on June 6, 1986, when the former went out of business (a new airline company with the same name formed eight years later).
The rudder is a fundamental control surface which is typically controlled by pedals rather than at the stick. It is the primary means of controlling yaw—the rotation of an airplane about its vertical axis. The rudder may also be called upon to counter-act the adverse yaw produced by the roll-control surfaces.
WASHINGTON (Reuters) -The Federal Aviation Administration said on Tuesday it issued a safety alert to airlines warning of the potential for limited or jammed rudder movement on certain Boeing 737 ...
Due to reorganizations in 1993 and 1998, the current Raymarine - at the time still under the name of the parent company - was created. In January 2001, Raymarine was formed when the division was acquired in a management buy-out backed by Hg. [4] In December 2004 the company was floated on the London Stock Exchange quadrupling Hg's investment. [5]
The yaw axis has its origin at the center of gravity and is directed towards the bottom of the aircraft, perpendicular to the wings and to the fuselage reference line. Motion about this axis is called yaw. A positive yawing motion moves the nose of the aircraft to the right. [1] [2] The rudder is the primary control of yaw. [3]
A rudder pedal is a foot-operated aircraft flight control interface for controlling the rudder of an aircraft. [1] [2] The usual set-up in modern aircraft is that each pilot has a pedal set consisting of a pair of pedals, with one pedal for each foot. Each right and left pedal works together so that one pedal pops out when the other is ...
The cause was initially a malfunction in two of the plane's rudder travel limiter units, followed by incorrect actions by the crew which eventually led the plane to stall while encountering a thunderstorm. The crew ignored the recommended procedure to deal with the problem and reset a circuit breaker which further disengaged the autopilot and ...
