  2. Vertical stabilizer - Wikipedia

    en.wikipedia.org/wiki/Vertical_stabilizer

    The vertical stabilizer is the fixed vertical surface of the empennage. A vertical stabilizer or tail fin [1] [2] is the static part of the vertical tail of an aircraft. [1] The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim ...

  3. 1963 Elephant Mountain B-52 crash - Wikipedia

    en.wikipedia.org/wiki/1963_Elephant_Mountain_B...

    Due to buffeting stresses, [2] the stabilizer shaft broke [1] and the B-52's vertical stabilizer came off the plane. It was found 1.5 miles (2.4 km) from where the plane struck the mountain side. [4] With the loss of the vertical stabilizer, the aircraft had lost its directional stability and rolled uncontrollably.

  4. Stabilizer (aeronautics) - Wikipedia

    A Boeing 737 uses an adjustable stabilizer, moved by a jackscrew, to provide the required pitch trim forces. Generic stabilizer illustrated. A horizontal stabilizer is used to maintain the aircraft in longitudinal balance, or trim: [3] it exerts a vertical force at a distance so the summation of pitch moments about the center of gravity is zero. [4]

    The flight control stick remained attached to the installation area while the top of the rudder and vertical stabilizers were found bent 90 degrees to the right. The airplane's engine was ...

  6. List of aircraft structural failures - Wikipedia

    en.wikipedia.org/wiki/List_of_aircraft...

    The list of aircraft accidents and incidents caused by structural failures summarizes notable accidents and incidents such as the 1933 United Airlines Chesterton Crash due to a bombing and a 1964 B-52 test that landed after the vertical stabilizer broke off. Loss of structural integrity during flight can be caused by:

  7. 1964 Savage Mountain B-52 crash - Wikipedia

    en.wikipedia.org/wiki/1964_Savage_Mountain_B-52...

    The 1964 Savage Mountain B-52 crash was a U.S. military nuclear accident in which a Cold War bomber's vertical stabilizer broke off in winter storm turbulence. [3] The two nuclear bombs being ferried were found "relatively intact in the middle of the wreckage", according to a later U.S. Department of Defense summary, [4] and after Fort Meade's 28th Ordnance Detachment secured them, [5] the ...

  8. American Airlines Flight 587 - Wikipedia

    en.wikipedia.org/wiki/American_Airlines_Flight_587

    The aircraft performance study indicated that when the vertical stabilizer finally detached, the aerodynamic loads caused by the first officer's actions produced 203,000 pounds-force (900 kilonewtons) of force on the rudder, meaning that the vertical stabilizer did not fail until far in excess of the 100,000 lbf (440 kN) of force defined by the ...

  9. Empennage - Wikipedia

    en.wikipedia.org/wiki/Empennage

    The empennage of an Atlas Air Boeing 747-200. The empennage (/ ˌ ɑː m p ɪ ˈ n ɑː ʒ / or / ˈ ɛ m p ɪ n ɪ dʒ /), also known as the tail or tail assembly, is a structure at the rear of an aircraft that provides stability during flight, in a way similar to the feathers on an arrow.
