Pre-Flight Planning and Crew Briefing
On March 15, 2011, according to the daily flight schedule, the crew of helicopter Mi-8T, registration RA-24436, consisting of an instructor pilot, a trainee captain (commander), and a flight mechanic, was scheduled to perform Task No. 245 for a medical evacuation flight operated by the Krasnoyarsk Air Ambulance. After passing the pre-flight medical check at 00:30 at the medical station of Cheremshanka Airport, the crew remained on standby in a designated room at the airport hotel. The crew was medically cleared for flight duties.
At 02:30, the planning dispatcher of AeroGeo LLC received a request from the air ambulance dispatcher for a medical task along the route: Cheremshanka – Tatyshev Island – Shushenskoye – Balakhta – Tatyshev Island – Cheremshanka. The dispatcher informed the crew. At 02:44, the flight plan was transmitted to relevant addresses, designating the flight as EG 9355 with a departure time of 03:00.
Pre-Flight Preparation
Pre-flight preparation was conducted by the crew in the navigation room of Cheremshanka Airport and at the helicopter, under the supervision of the instructor pilot. The weather forecast met the requirements for visual flight rules (VFR) operations. The helicopter was serviceable, had sufficient remaining service life for the mission, and was refueled with conditioned fuel and lubricants.
Planned Additional Training
It was previously planned by AeroGeo management and the crew that, after completing the medical mission, if sufficient daylight remained and crew duty time allowed, the instructor pilot would conduct training for the trainee captain according to Program A-2 "Introduction to Helicopter Commander Duties," Task No. 4, exercises 3 and 4 of the Mi-8 PPLS training program of AeroGeo LLC. These exercises involved traffic pattern flights and hovering with simulated engine failure (by throttling one engine).
