All 14 Superjet aircraft were manufactured in 2016.

Rossiya Airlines, one of the country’s largest carriers, is known to operate at least one affected SJ-100. The regional airline Azimuth is said to operate another SJ-100, Yamal five others, with the remaining aircraft in storage at various organizations, including the Sukhoi design bureau.

Inspections require dismantling parts of the plane, including the door-frame skin, lavatory module, as well as thermal and acoustic insulation.

The Sukhoi Superjet 100, rebranded as the SJ-100, is a cornerstone of Russia’s domestic commercial aircraft program, designed to reduce reliance on Western suppliers amid sanctions. More than 230 SJ-100s have been built so far, with roughly 100 currently holding active airworthiness certificates.
