An Antonov An-26B-100 transport plane crashed after striking powerlines near Mykhailivka, Ukraine, shortly after takeoff from Zaporozhye Airport (OZH). One of the three crew members suffered fatal injuries.

The aircraft had been stuck at OZH following the Russian invasion of Ukrainen that started on February 24, 2022. Almost two months later, UR-UZB was to be ferried to Uzhgorod Airport (UDJ), away from the OZH due to fighting going on in the vicinity.
In the 90 days prior to the accident, the captain had just flown for 85 minutes while the copilot and flight engineer had not made any flights.

The cause of the aviation incident (collision of an airworthy aircraft with an obstacle) was the decision of the captain to carry out the flight under Visual Flight Rules (VFR) conditions in foggy weather at a critically low altitude, leading to the loss of visual contact with the ground, uncontrolled increase in speed, and the aircraft colliding with a power transmission line.

Contributing Factors:
1. The flight crew's failure to decide to switch to instrument flight and climb to a safe flight altitude when encountering weather conditions that did not meet the visual meteorological flight conditions.
2. Likely use of altimeters by the flight crew to maintain flight altitude in meters when the altimeter mode was set to indicate altitude in feet.
3. The decision of the flight crew to fly at critically low altitudes with the radio altimeter and GPWS turned off.
4. The flight crew's failure to follow the departure procedure from the aerodrome area under VFR, which was discussed in detail by the flight crew during pre-flight briefings.
5. Deterioration of weather conditions after takeoff.
6. Low crew resource management (CRM) skills.
7. Retraction of flaps in a turn at an altitude lower than recommended and at a speed higher than recommended for the An-26 aircraft.
8. The complex emotional state of the crew during both preparation and execution of the flight due to combat actions conducted by the Russian Federation near the departure aerodrome.
9. Conducting the flight without meteorological support, which contradicts aviation regulations.
10. The absence of procedures for conducting flights under VFR at low and critically low altitudes for An-26 aircraft in the operator's manuals.
