On the morning of December 25, an Azerbaijan Airlines Embraer 190 carrying 62 passengers and five crew members crashed while attempting to land at Aktau Airport in Kazakhstan.

Flight J2 8243 took off from Baku and was originally scheduled to head to the Russian city of Grozny, but was diverted to Aktau due to heavy fog. The airline said the crew attempted an emergency landing about three kilometers (1.9 miles) from the city of Aktau in Kazakhstan.

Initial reports indicate that 40 people on board may have died. According to the Flight Safety Foundation’s Aviation Safety Network, the crash would be one of the most serious involving an E190. According to ASN, 44 people died in a crash of this type of aircraft on Henan Airlines in 2010.

The airline said that, according to preliminary data, 37 passengers were from Azerbaijan, 16 from Russia, 6 from Kazakhstan and 3 from Kyrgyzstan.

Flight tracking site Flightradar24 shows the aircraft taking off from Baku at 03:55 UTC, with contact to the ADS-B data initially lost at 04:40 UTC due to GPS interference. The track was recaptured at 06:07 UTC before being lost again at 06:28 UTC at the time of the crash.

Videos circulating online show the plane making a steep right turn before hitting the ground and bursting into flames.

Aviation Week Network’s Fleet Discovery database shows that the aircraft, registration number 4K-AZ65, was 11.5 years old and was delivered to the airline in July 2013. It had completed 9,474 hours on 6,296 flights.
