On the 16th of january 2017 a turkish Airlines Boeing 747-400 freighter was flying from hong kong to Istanbul’s Ataturk airport with a stopover at Manas international airport in Bishkek,kyrgyzstan. The flight was being operated by ACT airlines on behalf of turkish airlines. They were carrying about 84 tons of commercial cargo.
The plane lifted off from hong Kong at about 7:12 pm on the 15th of january. They were 2 hours late. The plane climbed and cruised with no issues to speak of. 41 minutes past midnight on the 16th of january flight 6491 entered the bishkek ATC area control center Flying at 34000 feet they'd have to start descending soon to make it into bishkek.
Soon afterward the crew asked for clearance to descend and after being cleared they descended down to 22000 feet. As they neared bishkek they checked in with ATC about the weather at bishkek, ATC tells them that the RVR or runway visual range is 400 meters. RVR is the visibility at the threshold of the runway. This means that to someone standing at the edge of the runway theyd be able to see 400 meters or 1300 feet down the runway. Not the best of situations but the pilots would be able to make do with the visibility. At 1:06 am the crew was handed off to the approach control who cleared the plane to descend down to 6000 feet. Approach control was going to try to set the plane up for an ILS approach onto runway 26. The approach controller then proceeded to give the crew the weather for their approach. The wind was calm, visibility was 50 meters,RVR was 300 meters. With the weather deteriorating the controller asked the crew if they wanted to continue the approach. The final decision in this situation was with the crew. They could abort the landing and go around if they felt like the weather was not conducive for a landing. The crew elected to continue the landing. The controller then gave them the landing clearance runway 26 was all theirs!
The controller gave the crew another weather update as they continued their approach quote "...wind calm... RVR in the beginning of the runway four hundred meters, in the middle point three hundred two five meters and at the end of the runway four hundred meters and vertical visibility one six zero... feet". The plane descended through dense fog, An automated voice calls out 500 signalling that they were 500 feet above the terrain, the pilot in command says continue, signalling that he wanted the approach to continue. As they approached minimums the First officer calls out approaching minimums! The pilot in command asks the first officer to look outside as they searched for the runway, but through the dense fog they could see little. An automated system says 100 they were now 100 feet off the ground the first officer again calls out minimums! The pilot in command says “ Negative go around”
they didn't have the runway in sight and half a second later the go around button was pushed. But they were at 58 feet when the go around button was pushed. The 4 engines surged to life and the pilots pulled back on the control column executing a missed approach. The right wing began to scrape trees along its flight path. The plane touched down on the ground with barely
