In 2010, a new runway 3300m long (05L/23R) and a new terminal with 3 air bridges were opened. The older runway (05R/23L) was repaired and now is used as a taxiway. A second module for the new terminal was completed in 2013. Chinese construction firm Weihai International Economic & Technical Cooperative Co., Ltd. performed the $160 million in upgrades to the airport.
On 19 September 1989 UTA Flight 772, a McDonnell Douglas DC-10-30 (registration N54629) operating the Brazzaville-N'Djamena-Paris CDG sector, was bombed 46 minutes after take-off from N'Djamena causing the aircraft to crash while flying over Niger. All 156 passengers and 14 crew members on board perished. For nearly 20 years, this incident marked the deadliest air disaster involving a French-operated airliner, in terms of loss of life. As of June 2009, it ranks as the second-deadliest (see Air France Flight 447).
