Russia’s Federal Air Transport Agency (Rosaviatsiya) has approved revised service life limits for the Sukhoi Superjet 100 (SSJ100), increasing the aircraft’s authorised operating life to 20,000 flights, 40,000 flight hours and 20 years. The change applies to aircraft powered by SaM146 engines, including the extended-range SSJ100LR variant, and was incorporated into the aircraft’s type certificate data sheet on 29 September 2026.
The revised limits replace the previous restrictions of 15,000 flights, 25,000 flight hours and 15 years, introduced in 2023. Russia currently operates 154 SSJ100 aircraft, making the extension relevant to the continued operation of the existing fleet.
The latest approval forms part of a phased programme to increase the aircraft’s authorised service life towards its original design targets. The manufacturer, Yakovlev, is using structural calculations, full-scale fatigue testing and in-service operational data to substantiate further extensions.
Vladimir Lavrov, chief designer of the Superjet programme, said the newly approved limits represent 40% of the aircraft’s design service life targets. Further increases will depend on demonstrating continued compliance with airworthiness requirements covering structural strength, fatigue life and corrosion.
The latest approval does not establish the SSJ100’s final service life limits. Yakovlev continues to assess the aircraft’s principal load-bearing structures to support further extensions, with the aim of sustaining airline operations over a longer period.
