The Russian Ministry of Industry and Commerce awarded a 4.5 million‑rouble research programme to lengthen the operational life of the Sukhoi Superjet 100, aiming to raise the aircraft’s flight‑hour limit from 15,000‑25,000 to 25,000‑40,000 and to increase the total number of flights from 10,000‑15,000 to 15,000‑20,000.
The programme also seeks to extend the service life of some Superjet variants to 20 years, with chief designer Vladimir Lavrov saying the new limits confirm the aircraft’s structural reliability and raise the assigned life to 40 % of the design values; the Superjet first flew on 19 May 2008 and entered service with Armavia in April 2011, later becoming a mainstay for Aeroflot, while Brussels Airlines withdrew four units in 2018 after technical failures.
