Aeroflot Flight N-63 was a scheduled domestic flight in the Soviet Union, executed by an Ilyushin Il-18 aircraft. The flight was en route from the city of Simferopol to Vinnytsia. As it approached Vinnytsia Airport, the aircraft encountered inclement weather that included heavy fog and poor visibility conditions, which complicated the landing process for the crew. During the approach, the plane struggled to maintain the necessary altitude and control, ultimately leading to a crash just short of the runway.

Following the accident, an investigation revealed that the pilots had possibly underestimated the impact of the fog alongside their airspeed and altitude management. The combination of these human errors with the challenging environmental conditions resulted in a catastrophic end, claiming the lives of 48 individuals aboard. The event marked one of the significant incidents in Soviet aviation history, prompting changes to regulations and procedures to improve flight safety standards.

Safety measures and protocols in aviation were reexamined post-crash, leading to stricter training requirements for pilots when facing adverse weather. The crash influenced policy adjustments within Aeroflot as well, shifting focus towards enhancing aviation safety and operational reliability. Moreover, it raised awareness about the need for better weather forecasting and improved pilot decision-making in complex atmospheric conditions.
