Flight Planning and Crew
On November 14, 2022, a flight assignment was issued for commercial flight AGU-9151, operated by JSC Angara Airlines under contract with Gazprom dobycha Irkutsk LLC. The aircraft was a Mi-8MTV-1 helicopter, registration RA-25830. The crew consisted of a pilot-in-command (PIC), co-pilot, flight engineer, and flight attendant. The planned route was from Irkutsk aerodrome to Nyuchakan landing site, then to Zhigalovo landing site, followed by UKPG 2 landing site, and back to Irkutsk.
Upon arrival at the aerodrome, the crew underwent a pre-flight medical examination at the Irkutsk airport medical unit and were cleared for the flight. The PIC received actual and forecast weather information for the route and recorded it in the pre-flight weather preparation log at 07:10 local time. The PIC decided to conduct the flight under visual flight rules (VFR).
Departure and First Leg
After aircraft preparation, six passengers boarded the helicopter. At 01:01 on November 15, 2022, the PIC took off and flew to Nyuchakan landing site (Figure 1 in the report). Landing at Nyuchakan occurred at 02:57. The passengers disembarked.
Refueling Stop
The crew then repositioned the helicopter to Zhigalovo landing site for refueling (Figure 2). According to the PIC's account, the helicopter was refueled with a total of 3,000 liters at Zhigalovo. The PIC obtained an updated weather forecast via the internet, which he determined to be suitable for the continuation of the flight.
The report excerpt concludes with the takeoff from Zhigalovo, without further details on subsequent legs or the flight's conclusion.
