According Aviaforum.ru (basically the Russian and CIS PPrune), a renowned user has just posted (using my google translator)»»»
"The plane that crashed yesterday after two engines failed in Afghanistan was flown by pilots Dmitry Belyakov and Arkady Grachev. The first was 41 years old, the second - 42. The other two people listed as crew members were previously doctors who accompanied the sick Anna Evsyukova and her husband Anatoly during transportation from Pattaya (Utopao) to Moscow (Zhukovsky). It was a registered ambulance flight, but in fact it was a commercial flight. However, both pilots only had private pilot certificates, meaning they could not fly commercial flights. These certificates were issued to them by the North-West Territorial Administration of the Federal Air Transport Agency in September 2023. Dmitry Belyakov has a total flight time of 2.4 thousand hours, while Arkady Grachev has only 870 hours. On the Falcon 10, the pilots had minimal flying experience. Both trained for this type of aircraft only last year. The FlightSafety International training center issued them with a document confirming their training for this business jet in May 2023. The operator of the business jet that crashed in Afghanistan, Athletic Group LLC, did not have any certificates for flights. According to the Rosaviatsiya website, the company did not have certificates for commercial air transportation, aviation work, or a general aviation operator’s certificate. Accordingly, she could not operate commercial flights. Permission to fly the Falcon 10 was issued as a non-commercial one. The flight was declared empty, with no passengers or luggage, and only two pilots. Previously, air transportation of a married couple and doctors was illegal. PS: So you don’t even have to wait for Monday."
You can also see there some actual pics of this Falcon already with the russian reg RA- as well the takeoff video from a nearby Moscow aerodrome to destination Thailand two days ago.
