The second of four SSJ100 prototypes SN95003 took to the skies on December 24, thus joining the flight test program started earlier this year.
The aircraft took off from the factory runaway and safely landed after a successful 2h 30min. flight at the altitude up to 6000 m.
The airplane performed traditional stability and handling quality as well as systems’ checks in accordance with the first flight assignment. SSJ100 SN95003 was captained by Leonid Chikunov, Sukhoi Civil Aircraft test pilot, who flew with Nikolai Pushenko, also a test pilot. “With a number of software modifications introduced on SN95003 basing on the results of the flight envelope evaluations done on the first prototype, the aircraft demonstrated remarkable stability and handling qualities. Both flight test engineers and pilots are quite pleased with the overall performance of the second prototype. The aircraft looks trouble free and I expect it to join our ongoing certification test campaign at the earliest”, said Leonid Chikunov.
The first two prototypes SN95001, launched in May, and SN95003 are to perform the larger part of the certification program. In the course of 398 flights the both airplanes fitted with heavy on-board measurement instrumentation will perform a wide range of tests including overall performance, stability and control, engine and systems performance, hot & high trials, cold weather trials etc.
Sukhoi Superjet 100 SN95001 has already spent more than 200 hours in the skies. “Since May 19, when the first airplane took to the skies, we’ve done quite a lot. As test pilots we go much beyond a flight envelope an airline pilot will usually fly. We are to be absolutely sure that in a critical situation the airplane will behave in the expected way. In November, along with the systems and overall performance evaluation trials, we conducted the first series of high angles of attack testing. And it’s encouraging that the airplane behaves in a predictable way, every average pilot can manage”, said Alexander Yablontsev, Sukhoi Civil Aircraft Chief Test Pilot, commenting SN95003 SSJ100 flight trials.

SSJ100 aircraft with horizontal winglets (saberlets) has successfully accomplished a series of flight tests following the results of which Sukhoi Civil Aircraft Company has obtained a Major Change Approval from the Federal Air Transport Agency of the Russian Federation. First aircraft with the winglets has been delivered by SCAC to Severstal Aircompany (AC tail number is RA89135).
