Sukhoi Superjet 100 faces multiple incidents as airworthiness issues plague Russian fleet

Russia's Sukhoi Superjet 100 has faced three incidents in one week, including engine fires and emergency landings. Over half of the fleet, only 93 out of 230, currently holds airworthiness certificates due to issues with fuel filters and sanctions affecting parts supply. The incidents involve Azimuth Airlines, with problems linked to a shortage of fuel filters. Reports indicate that the quality of Russian-made filters is inadequate, leading to increased technical failures in the Superjet fleet. Production of the Superjet was expected to resume in 2024, but no new aircraft have been delivered since sanctions began nearly three years ago. Russia's civil aviation sector struggles to maintain its fleets, with many grounded due to lack of parts and maintenance issues.
