The key components, essential for Russian Mi-8 military helicopters and manufactured by Czech company První brněnská strojírna (PBS) Velká Bíteš, reportedly reached Russia through intermediary companies in Kazakhstan and India following the commencement of the Ukrainian invasion. The Ukrainian news source relies on data from the NGO State Watch, suggesting that the Czech firm may have violated European Union sanctions imposed against Russia. The Ukrainian NGO State Watch bases its claims on export registers, indicating that the Indian company Space Era Materials and Processes sold 20 key components to Russia over the past two years, amounting to $8.5 million (CZK 190 million).
