The plane crashed when attempting to return after a loss of engine power after takeoff. Both occupants were injured.
Conclusion
The accident with RA-0679G took place in the afternoon in visual weather conditions during a forced landing. The necessity of the forced landing was caused by the alternating failure after the takeoff of the right and then left engines.
Most likely, the reasons for the drop in engine speed were:
- Insufficient fuel supply to carburettors due to increased resistance of installed paper fuel filters (not complying with the recommendations of the engine developer) when using a mixture of fuel and oil, and reduced productivity of fuel pumps due to the development of valves;
- possible cavitation of fuel in sunny weather (fuel system pipelines are black, hoods are not provided by design), high ambient temperature (+25°C) and long time of taxiing (25 min) BC for the executive start.
These design flaws (installation of paper-based aircraft in the fuel system) fuel filters not provided by the developer and fuel pumps with (b) were not identified by the commission of CJSC NPC "Expertise" at Certification of engines as part of the plane for compliance with the requirements of FAP-118 due to failure to carry out the certification work in full, and Lack of knowledge of the Rotax 582UL engine design by members of the commission.
