Loss of control (aeronautics)

A loss of control is when an aircraft starts to flip or rotate without pilot controls and is the cause of many disasters including china northwest flight 2303 United Airlines Flight 585, copa airlines panama flight 201, Alaska airlines flight 261 and Aeroflot flight 4227

effects on aircraft

some examples are:

China Northwest Airlines Flight 2303 took off from Xi'an, china. the aircraft a Russian tupolev 154 was in for maintenance before it's flight and the autopilot yaw-channel had been erroneously connected to the bank control, and the bank-channel to the yaw controls.Additionally, this incorrect maintenance was not done in a properly approved facility. while flying the engaged the autopilot then the plane began to oscillate violently, any attempts by the autopilot to rectify matters only made things worse. The plane shook itself to pieces and broke itself up in midair before the crew could react. the wreckage was discovered, all 160 people died when the plane broke itself up and crashed near Xi'an.

Alaska Airlines Flight 261 took off from Mexico and was on it's way to California. the md-83 was in for maintenance and the t-tail's jackscrew was not checked and caused the lives 88 lives. the plane dived two times the last dive caused the the ailerons to tear off and flipped upside down, the pilots even tried to fly the plane inverted but all attempts were useless. the plane nose dived and crashed into the pacific ocean.

Copa Airlines Flight 201 was preparing too land in fierce thunderstorms and the pilots were getting false readings and was a very shockingly similar accident, a year earlier another Boeing 737-200 flipped, rotated and crashed killing 25 people in Colorado Springs. the plane then entered into a steep dive of an angle of 100 degrees to the right side and rolled uncontrolable to the ground, until it passed the speed of sound and as a consequence, the plane passed the speed limit to hold itself. The pilots tried to level up the aircraft as a desperate and heroic try to save the plane, but it crashed in a jungle area of the Darien Gap at the speed of 400 knots (460 miles per hour), killing all 47 passengers on board instantly.

Aeroflot flight 4227 took of shortly from Almaty international airport to Simferopol Airport, the tupolev entered an altitude of no more then 500 and was in a zone of hot air, the plane entered a steep nose dive and stalled the crew lost control and crashed killing 163 people.
