• leaning of the fuel-air mixture resulted from a "vapor lock" origination in the engine fuel system due to the engine continuous running at the parking place and during the ground maneuvering at the engine power configuration;

• using the automobile gasoline AI-92 with MTBE fuel dope which do not meet the aviation fluel requirements recommended by the aircraft flight and maintenance manuals;
