Circumstances:
On a night approach to Kiev-Zhuliany Airport, while initiating a fourth turn to join the approach path, the airplane struck the ground at a speed of 420 km/h, gear and flaps up. It crashed in a huge explosion in a field located 16 km west of the airport. The aircraft was totally destroyed and all 29 occupants were killed.
Probable cause:
The crew continued the approach by night without proper settings related to the atmospheric pressure. The following contributing factors were reported:

- The airfield pressure on altimeters was not established,
- ATC instructions to reduce the approach speed, transmitted twice, was not respected by the crew,
- The fourth turn on final was initiated too late and only following an ATC reminder.
