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 NTSB asserted that the A300-600 rudder control system was vulnerable to excessive rudder inputs. [21] The Allied Pilots Association, in its submission to the NTSB, argued that the unusual sensitivity of the rudder mechanism amounted to a design flaw that Airbus should have communicated to the airline. The main rationale for their position ...
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 ...
China Airlines Flight 006 was a daily non-stop international passenger flight from Taipei to Los Angeles International Airport.On February 19, 1985, the Boeing 747SP operating the flight was involved in an aircraft upset accident, following the failure of the No. 4 engine, while cruising at 41,000 ft (12,500 m).
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 ...
A balanced rudder is a rudder in which the axis of rotation of the rudder is behind its front edge. This means that when the rudder is turned, the pressure of water caused by the ship's movement through the water acts upon the forward part to exert a force which increases the angle of deflection, so counteracting the pressure acting on the after part, which acts to reduce the angle of deflection.
