The aircraft departed Vigo-Peinador Airport in Spain, bound for Istanbul Airport in Turkey, with eight people aboard, seven crew and one passenger, which was a cargo escort. Flight 4050 was a cargo flight, carrying 10 t (10 long tons; 11 short tons) of cargo, with the intention to stop-over on Lviv International Airport, in Ukraine for refueling, before continuing to Istanbul.
The aircraft was approaching Runway 31, on heading 310, in difficult weather conditions; although there was little wind, vertical visibility was only 60 metres (197 ft), while visibility near the ground was 250 metres (820 ft) and Runway Visual Range (RVR) was 800 metres (2,625 ft).
The crew declared an emergency and started to perform an emergency landing, but failed to reach the runway. The aircraft impacted the ground at 7:10 a.m. just 1.5 kilometres (0.93 mi; 0.81 nmi) before the Runway 31 threshold, close to the village of Sokilnyky. The cockpit section broke off on impact, then the cargo shifted, crushing and killing five occupants.
Emergency response
At 7:29 a.m. the crew member called and reported the aircraft performed an emergency landing. At 7:40 a.m. the wreckage of the aircraft was located 1.5 kilometres (0.93 mi; 0.81 nmi) from Runway 31. By 9:00 a.m. it was determined there were eight people aboard. Three of them were found seriously injured and they were taken to the hospital. Three bodies were also found, while two were still missing. Later two missing bodies were found, all dead. It was finally determined five people perished in the crash, at least four of them were crew, and the sole passenger, a cargo escort.

Lviv's mayor

Investigation
The National Bureau of Air Accidents Investigation of Ukraine (NBAAI) opened officially investigation of the accident on 9 October, four days after the crash. The on-site work of the commission took place between October 5 and 7. In this action two black boxes were recovered and were in good condition and able to provide data. The other information, such as air traffic control communication, radar data, weather information, emergency service response and ground based navigation aids at the airport were also collected.
The final report was published by NBAAI on 8 October 2021 concluding that the probable cause was, "the most probable cause of the accident, collision of a serviceable aircraft with the ground during the landing approach in a dense fog, was the crew’s failure to perform the flight in the instrument conditions due to the probable physical excessive fatigue, which led to an unconscious descent of the aircraft below the glide path and ground impact."
Aftermath
The day after the crash Ukraine Air Alliance was banned from operating flights in European Union airspace. On 7 October 2019, State Aviation Administration of Ukraine announced that air operator's certificate of Ukraine Air Alliance was terminated effective 5 October 2019, 00:00 UTC after an accident.
