An Antonov An-28 operated by East Wing was destroyed when it impacted terrain during an ambulance flight in Kazakhstan.
The aircraft took off from Almaty at 18:35 hours local time with destination Shymkent, Kazakhstan. It impacted terrain and caught fire 12 minutes later, near the village of Mezhdurechenskoye. All five on board suffered fatal injuries.

Probable Cause:

The probable cause of the accident was the shutdown of engine no. 2 and then engine no. 1 (possibly due to a faulty shutdown).
In the course of the subsequent emergency descent due to complete loss of power of the engines with no radio communication with air traffic controllers, as well as possibly due to the resulting confusion and nervousness, the crew unintentionally forgot to switch the pressure value on the mechanical barometric altimeter of the aircraft to the pressure on the landing airfield (704 mm Hg), leaving the pressure value of 760 mm Hg, which led to incorrect readings of true altitude of the flight.
Subsequently, the crew was able to start the engines and attempt to make a forced landing at a distance of 28 km from the airfield of Almaty at night in poor weather conditions in an unlit area.
Incorrect readings on the barometric altimeter of the true flight altitude (the radio altimeter showed 750 m) resulted in the aircraft colliding with a power line, causing a fire, as well as colliding with the ground, as a result of which the aircraft structure completely collapsed and burned down.
