According to the Russian news outlet Kommersant, the Sukhoi Superjet 100, a domestically-produced Russian aircraft, has experienced multiple incidents over two consecutive weeks. On November 25, Simple Flying reported an Azimuth airline Superjet encountered an engine fire while landing in Turkey. Following this, on December 1, another Azimuth Superjet made an emergency landing at Russia's Mineralnye Vody Airport. Notably, more than half of the Superjet fleet currently lacks Russian flight certificates.
Kommersant detailed that two Azimuth Airlines Sukhoi Superjets were involved in three separate incidents within a week. The first occurred on November 24 when one of the jets suffered an engine fire upon landing. Another incident took place on November 28 when a different Azimuth Superjet was unable to take off from Saransk due to engine failure. The same aircraft had to make an emergency landing on December 1 because of a fuel filter malfunction error.
The publication attributes the fuel filter issue not to the quality of aviation fuel but rather to a shortage of fuel filters in Russia. International sanctions have hindered Russia's ability to source new filters. United Engine Corporation, a state-owned company responsible for engine production, has supplied import-substituted fuel filters; however, there are reports these are clogging up on the Superjets.
