Turkish Airlines Flight 6491 was a scheduled international cargo flight operated by ACT Airlines on behalf of Turkish Cargo, from Hong Kong to Istanbul via Bishkek, Kyrgyzstan. On 16 January 2017, the Boeing 747-400F flying the route crashed in a residential area while attempting to land in thick fog at Manas International Airport, Bishkek. A total of 39 people – all four crew members on board and 35 residents on the ground – were killed. It was Kyrgyzstan's deadliest plane crash since the crash of Iran Aseman Airlines Flight 6895 in 2008.
The subsequent investigation found that the aircraft failed to acquire the correct instrument landing system's signal. Due to a series of errors by the pilots, the aircraft flew significantly higher than the proper altitude for approach. The autopilot then picked up a false glide slope signal. Believing that they had captured the correct glide slope, the pilots let the autopilot put the aircraft into a descent. It then crashed into a residential area past the runway, mere seconds after a go-around was initiated.
