OREANDA-NEWS. April 15, 2010. The fourth Sukhoi Superjet 100 flight test prototype SN95005 flew from Komsomolsk-on-Amur to Zhukovsky-based Sukhoi Civil Aircraft Company Flight test center to continue flight certification campaign.

Flight certification campaign tests scheduled for this aircraft include the evaluation of on-board equipment and, together with 95004, systems failure safety. SN95005 will accomplish tests on both fire protection and inertial gas systems. Sukhoi Superjet 100 is the first Russian aircraft to feature inertial gas system .

Its implementation is a must according to the American and European aviation authorities introduced to enhance flight operation safety. Inertial gas system fills the fuel tank with nitrogen deployed from the air in proportion to the fuel consumed.

Its application allows preventing fire and detonation of fuel fumes in case of unfortunate critical landing, in particular, when the aircraft touches the runway with! the wing.

Further on, Sukhoi Superjet 100 SN95005 will be the vehicle for first customers’ pilot training. “Today the entire company is focused on certification campaign and aircraft production for our first customers. We sustain dynamic pace not only in terms of flight campaign, but also in fatigue tests.

Novosibirsk had already performed over 4950 laboratory flights, by the month end this shall equal 6000. In terms of static testing we are successfully through the main part of operational and design loads, only particular cases are left – such as passenger chair installation strength, etc. By the end of April we expect to power the first ramp-up production aircraft 95007. The key factor now is to have all partners on the project to enlist all efforts in reaching the outlined milestones”, - noted Vladimir Prisyazhnyuk, Sukhoi Civil Aircraft Company President%uk upon fourth Sukhoi Superjet 100 flight test prototype SN95005 arrival to Zhukovsky.
