Investigation Summary
The flight was a domestic cargo operation from Pointe Noire to Brazzaville. At the time of the approach, Brazzaville was experiencing a tornado and heavy thunderstorms with visibility reduced to 4,000 meters. The aircraft, which still bore the 'HeavyLift Congo' livery despite being operated by Aéro-Service and leased from Air Highnesses, failed to maintain the glide path. It first struck two large tree branches at 1,080 meters from the threshold, then clipped six smaller trees and several houses at 1,015 meters. The main wreckage plunged into a ravine 870 meters short of the runway. Post-crash confusion led to conflicting official statements. Early government reports claimed the aircraft overran runway 23R due to brake failure and a failed go-around, but physical evidence and METAR data supported a short-landing scenario on runway 05L. The aircraft's registration and ownership were also subjects of significant scrutiny, involving a complex web of Armenian companies and alleged links to military officials. The flight data recorders were recovered and sent to the Interstate Aviation Committee (IAC) in Moscow for analysis in February 2013, but a final report has not been publicly released.
Final Conclusions
The investigation remains under the jurisdiction of the Ministry of Transport of the Republic of the Congo. As of the last update from the Interstate Aviation Committee (IAC) in February 2013, the flight data recorder and cockpit voice recorder had been received for readout. Both units exhibited mechanical damage from impact forces, requiring reconstruction efforts. No final determination of cause has been published by the Congolese authorities.
