Introduction
On August 8, 2022, two flights were planned for forestry aviation work using a Cessna 177RG aircraft with registration RA-2009G in Class G airspace. The aircraft was involved in an accident on that day; the following details are based on the investigation report concerning pre-flight preparations.
Pre-Flight Maintenance and Fueling
On August 7, 2022, a technician, under the supervision of the pilot-in-command (PIC), performed operational preparation of the aircraft for the upcoming flights. The aircraft was fueled with 210 liters of AI-100 automobile gasoline. The second pilot conducted the pre-flight inspection and drained fuel samples. Additionally, one quart (930 ml) of oil was added to the engine by the technician under the PIC's direction. The oil level in the tank was sufficient for the planned flight time on August 8.
Crew Medical Examination
On August 8, between 05:32 and 05:45, the crew (PIC, second pilot, and observer) underwent a pre-flight medical examination at the medical unit of Ukhta Airport. The examination was recorded in the inspection log.
Weather Information
Meteorological information was provided to the second pilot at 05:55 at AMSG-3 Ukhta before the first flight. This included forecasts and actual weather for Ukhta Airport, the route, and alternate airports. The PIC also received additional weather data from the controller before takeoff. The forecast and actual weather were consistent with the flight assignment, and the PIC decided to proceed with the planned flights.
Flight Execution
According to the technician, the PIC actively piloted the aircraft on all phases of the flights on the day of the accident. The first flight was performed by the PIC, but the investigation report does not provide further details about the accident sequence. The takeoff weight and center of gravity before the last flight could not be determined due to missing technical documentation.
