From the Wikipedia article
On 25 October 1962 the accident of Aeroflot Tupolev Tu-104 CCCP-42495 occurred, when a Tupolev Tu-104 crashed on takeoff for a test flight, killing all 11 occupants.
Sequence of events
At the time of the accident visibility was 30 km. The Tu-104 lifted off at 10:33 heading west (248°) after a takeoff run of 1,550–1,600 m and began to roll to the left. First the Tupolev grazed the ground with its left wing at 90° of left bank, before it smashed upside down into a forest at 150° of left bank, seconds after lifting off. Both the landing gear and the landing flaps (10°) remained extended.
Investigation and cause
Cause
During maintenance the mechanic had accidentally swapped the aileron cables, which is why the ailerons deflected in the opposite direction in each case, especially since the design of the Tu-104 did not prevent this either. Afterwards the mechanic also did not deflect the control wheel to check his work for errors. His supervisor did not check him; he was also not trained, and for the engineer it was the first inspection without guidance. Finally, Captain Rodionov, who allowed 6 technicians on board although they were superfluous for the test flight, also forgot to deflect the ailerons during the takeoff preparations.
