Flight Details
On 21 March 2020, a Bell-206B-III helicopter, registration RA-01917, conducted a flight from the waypoint "Baza Transit" to "Mys Konstantinovsky" as per a telegram issued on 20 March 2020 (No. 201243). The planned route was a direct track covering a distance of 140 km with a true course of 45°. The helicopter carried one passenger and approximately 30 kg of cargo.
According to the passenger, the flight was undertaken on the pilot's personal initiative, who offered to show the passenger coastal landmarks.
Pre-flight Preparation
The pilot-in-command arrived at the Baza Transit waypoint at approximately 06:00 and began pre-flight preparations. He obtained necessary meteorological information for Naryan-Mar airport, the en-route area, and the destination landing site using the internet. The pilot did not undergo a medical examination before the flight, which is consistent with the requirements of the federal aviation regulations (FAP-128, paragraph 8.10.1 allows the pilot to self-assess fitness when a medical worker is unavailable at the departure site).
The pilot conducted the helicopter's pre-flight preparation himself. He performed refueling with aviation kerosene TS-1 from a storage container in the hangar where the helicopter was kept. No pre-flight entry was recorded in the helicopter's logbook, so the investigating commission estimated the total weight using available data.
Weight and Fuel Estimation
The commission determined the following:
- Fuel load: approximately 340 liters (272 kg, assuming fuel density of 0.8 kg/l).
- Engine oil: 5.8 kg.
- Cargo: approximately 30 kg.
