A SILA Siberian Light Aviation Antonov AN-28, registration RA-28728 performing a flight from Kedrovy to Tomsk (Russia) with 15 passengers and 4 crew, was enroute about 100nm west of Tomsk when radio and radar contact was lost, the signal of an ELT was picked up afterwards in the vicinity of the village of Bachkar and the coordinates established at N57.38 E80.38. Rescue and Recovery Teams are on their way to the site. The aircraft was found upside down, however, everybody survived, one of the pilots received a serious injury (broken leg), all others escaped with minor or no injuries.

According to initial information the crew did not report any problems or anomalies with the flight. The crash site is in an area of dense forest which hinders the search as nothing appears to be visible from the air. A search on the ground has been initiated.

The aircraft was found by rescue teams, all occupants survived and are being taken to hospitals. According to preliminary information the crew performed a forced landing in an open area following at least one failed engine. A number of Russian media report quoting survivors both engines of the aircraft had failed.

Russia's Ministry of Emergencies reported the aircraft carried 15 passengers and 3 crew, all were rescued. The captain suffered a fractured leg, all others suffered minor injuries like bruises only. The rescue operation has been completed, 12 people are being flown to Tomsk via a helicopter, the rest are taken to Tomsk via bus.

Russia's MAK opened an investigation into the accident stating the aircraft carried two pilots, two technicians and 15 passengers. There were no fatalities, the aircraft sustained substantial damage. A commission has been formed to investigate the accident.

On Jul 20th 2021 the captain of the flight reported they went into a thick cloud and icing occurred resulting in the failure of both engines. The crew thus took decisions a lightning speed, the passengers had already understood something unusual had happened and followed the instructions to buckle up properly, while the crew began to look out of a location to put the aircraft into. They selected an area with small thin trees. Only when the wheels touched the ground they realized the ground was actually a swamp. The wheels sunk in causing the aircraft to topple over. Fortunately all passengers were buckled in and now hang in their seats upside down. The first officer got out of his seat and helped the passengers out, only after all passengers had been out of the aircraft and in a safe distance they noticed the captain's leg had badly swollen. The ELT was activated and rescuers quickly found their location from the ELT signal and smoke from a fire, they discovered the overturned aircraft but had problems to choose a landing site. The captain underwent surgery to fix his broken leg.

On Jul 21st 2021 meteorologists explained there was an area of high humidity and freezing temperatures in the Bachkar region, ceiling being at about 500-800 meters and tops at about 3000-4000 meters with the temperatures reaching freezing in between. The aircraft was at 2800 meters (about 9000 feet) climbing up to 3000 meters/FL100 when the engines failed likely due to both engine inlets icing up. It needs to be explained why the aircraft entered a zone of potentially dangerous weather conditions and why the anti-ice systems of the engines did not prevent the engines icing up.

On Jul 22nd 2021 Rosaviatsia reported the captain had 7300 flight hours total, 3970 hours on type, the first officer 155 flight hours on type. A secondary cold front was moving over the accident area. The height of the freezing level was 2500 meters. According to preliminary data both engines failed while the aircraft was climbing out of Kedrovy. Rosaviatsia has registered 7 occurrences involving an AN-28 since 1991 associated with engine failure in icing conditions, one resulting in an accident, 3 in serious incidents and 3 in incidents. All events were caused by either human error operating the engine de-icing or by failure of the engine de-icing system.
