Overview
The accident investigation report for an Antonov An-2, registration RA-17951, was received by the Interstate Aviation Committee (IAC) more than seven months after the occurrence. The exact date and time of the event could not be reliably determined. Due to the lack of objective information, the description of the flight and circumstances is based on statements from the pilot-in-command (PIC), representatives of the operator OOO "Voskhod", and witnesses.
Flight Details
The planned route, pre-flight preparation, meteorological conditions, and the aircraft's loading characteristics (both quantitative and qualitative) could not be established. No application for the use of airspace was filed. According to the PIC's explanation, he was in Yakutsk in July or August when he received an offer from a representative of OOO "Voskhod" to conduct a test flight of the aircraft on a non-commercial basis. He agreed, gathered the necessary documents (which he claimed entitled him to operate the aircraft), and submitted them to the representative.
Crew Statements
The PIC stated that after submitting documents, he was directed to the An-2 RA-17951. He noted that there was no dispatcher at the location and that takeoff permission was obtained from the company administration via a cellular telephone. He requested and received clearance from the administration, though he did not know who specifically authorized the flight. On board, in addition to the PIC, there was a second pilot (identified only by surname F. and given name I.). No other persons were on board. The flight took off after receiving clearance, but the report does not provide further details of the flight or its outcome.
Investigation Limitations
The report highlights significant gaps in information: the inability to determine the date, time, route, weather, and loading conditions. The absence of a filed flight plan and the reliance on verbal permission from the company administration suggest a lack of formal oversight.
