Pre-Flight Planning
On 9 September 2009, according to flight assignment No. 54, a Yakovlev Yak-40 aircraft (registration RA-87447) operated by Bugulma Air Enterprise (BAE) was scheduled to perform a charter flight (BGМ 9401) on the route Kazan – Begishevo – Aktobe (Aktubinsk). The assignment was issued on 8 September 2009 by the commander of the BAE aviation squadron and the deputy general director of BAE for flight operations. The client for the flight was the general director of OJSC SMP-Neftegas.
Crew and Medical Checks
The crew consisted of the aircraft commander (PIC), the co-pilot, the flight engineer, and the flight attendant. According to the readiness checklist, the crew completed preliminary training on 7 September 2009 at the Bugulma aerodrome (BAE's home base) under the supervision of the deputy commander of the BAE squadron, with the participation of the senior navigator and senior flight engineer. On 9 September 2009 at 04:40 UTC, the crew underwent a medical check at the medical unit of Kazan Airport and began pre-flight preparations. The pre-flight preparation was led by the PIC and monitored by the duty navigator of Kazan Airport.
Schedule Changes
During pre-flight preparation, the client requested an urgent change to the route and departure time. The proposed new plan was a direct flight from Kazan to Aktobe with a departure time of 08:30 UTC. Later, due to the client not arriving, the departure was postponed to 11:00 UTC. Despite the interval between the pre-flight medical check and the scheduled departure exceeding six hours, the crew did not undergo a repeat medical check. According to the decision acceptance log and issuance of dispatch clearances at Kazan Airport, at 10:24 UTC the PIC made a decision (the rest of the sentence is cut off in the source).
