Kairbolat "Nikolai" Sainovich Madyonov (Kazakh: Қайырболат Сайынұлы Майданов, romanized: Qaýırbolat Saýınulı Maýdanov, Russian: Николай Саинович Майданов; 7 February 1956 – 29 January 2000) was a legendary Kazakh helicopter pilot who was awarded both the title Hero of the Soviet Union and Hero of the Russian Federation, making him one of only four people awarded both titles.

He fought in the Soviet-Afghan war and was later mortally wounded when his helicopter was ambushed by Chechen rebels while he was evacuating Russian soldiers from the Argun Gorge.

The terrain and weather in Afghanistan were very difficult for flying helicopters in, but he nevertheless flew his Mi-8 very well, deploying paratroopers and rescuing wounded soldiers.

He made runs to pick up troopes from different locations and became very overweight from so many soldiers inside, but he managed to make a safe takeoff.

On 29 January 2003 he was ordered to fly troops into the Argun Gorge, and due to poor intelligence information, his helicopter came under attack by terrorists.

He made the decision to go and pick up paratroopers to save them from being ambushed, but the terrorist snipers were aiming at helicopter pilots, and a bullet his instruments and then ricocheted into his chest and shrapnel hit his neck.
