Rosaviatsia approved an amendment that extends the authorised service life of the Sukhoi Superjet 100 from 15 to 20 calendar years and raises the flight limits from 15,000 to 20,000 flights and from 25,000 to 40,000 flight hours.
The extension applies to SaM146‑powered SSJ100 aircraft, including the RRJ‑95B‑100/LR‑100 variants, and is based on engineering calculations, full‑scale structural testing and operational experience assessments; programme chief designer Vladimir Lavrov described the new limits as an intermediate step toward the original design targets, while Rostec reports that 154 SSJ100s are currently in operation in Russia.
