Prvni brnenska strojirna Velka Bites, a. s. is a Czech engineering and manufacturing company. It focuses mainly on the development, testing, and production of devices for the aircraft industry. Together with PBS Energo, a.s.; PBS Brno, a.s. and PBS Aerospace Inc., PBS VB is a member of PBS GROUP, a.s.
Soon after the Russian invasion of Ukraine, the EU, the U.S., and Canada, among others, imposed sanctions against the Mi-8s producer, Kazan Helicopter Plant (KHP). As a result, PBS Velka Bites stopped deliveries to Russia after 20 years of uninterrupted supplies. However, a Trap Aggressor investigation conducted exclusively for the Kyiv Independent revealed that Mi-8-specific power units made by PBS Velka Bites continue to reach Russia via intermediaries in Asia.
