Sukhoi Superjet 100 – 12 flights, over 30 hours in the sky. Second prototype is powered on

The Sukhoi Superjet 100 aircraft, powered by 2 SaM146 engines provided by PowerJet, scored over 30 hours in-flight during the first stage of factory-based flight tests, with an average flight lasting 2 to 4 hours.

At this stage the test program goal is to conduct initial in-flight evaluation of aircraft aerodynamics and general performance. Aircraft systems and equipment functioning are checked at various configurations of wing control surfaces with both retracted and extracted landing gear positions. The testing was performed at an altitude ranging up to 3000 m with 35000-40000 take-off weight at 670-680km/h maximum speed.

Summarizing the results of the first series of flights the SSJ100 pilots highly commended the aircraft's stability and control at all tested modes, including take-off and landing. The aircraft also demonstrated a good climb rate.

Even at this stage, flight data analysis of the aircraft's static and aerodynamic performance corroborate the aerodynamic, system and simulation data, earlier obtained through the large series of bench-testing. Flight, take off and landing performance at large confirm the design objectives.

The first stage of factory-based flight tests produced the first in-flight hourly fuel consumption rate. Its projection over the cruise mode shows that the aircraft consumes less than 1.7 tons per hour, which justifies the competitive advantages in terms of fuel efficiency declared earlier.

As the certification flight campaign will employ four SSJ100's, SCAC's flight team introduced additional crews – On June 29 Nikolay Pushenko performed his first SSJ100 flight, and on July 2 Leonid Chikunov captained the aircraft for the first time.

Concurrently with flights, the production sites in Komsomolsk are manufacturing both further prototypes and the aircraft intended for delivery. All aircraft systems have already been installed on SSJ100#95003 and it has been powered on, allowing for factory system trials. SSJ100#95004 had its fuselage joint with the outer wing and is currently fitted with the systems. Assembled fuselage of the fourth flight aircraft (SSJ100#95005) has been recently shipped to the final assembly shop, while outer wing

production is in completion. In the meantime, KnAAPO is putting together centre, cabin and rear sections of the fatigue aircraft (SSJ100#95006).

All manufacturing sites – KnAAPO, NAPO, and VASO – continue parts production for the first four aircraft to be delivered to airlines. The centre section assembly of the first delivery aircraft, the seventh in succession of the SSJ100 family, began in Komsomolsk in June.

As a part of the total technical upgrade of production sites, Brotje team is completing the installation of the automated fuselage/wing assembly rig, to assemble the first aircraft intended for delivery.

Upon completion of the first stage of factory flight tests Sukhoi Civil Aircraft Company performed an integral assessment of key systems and the components delivery schedule for both prototypes and the aircraft intended for the airlines. This assessment, combined with the standard certification test campaign agenda, lead to a need to revise the Programme schedule. According to the Sukhoi Superjet 100 Programme schedule the type certificate shall be obtained in mid 2009, followed by the first deliveries in 3Q09.

Certification Campaign

The certification flight test campaign will involve four flight aircraft; each of them given a specific role. Aircraft specific task defines their equipment – the first and the second flight aircraft, for instance, will not have a passenger cabin interior. They are intended primarily for evaluation of flight, take-off and landing performance, stability and controllability, as well as strength characteristics. Later, they will be employed in the most hazardous tests at high angles of attack and stall, undergo aeroelasticity and flutter safety tests.

The third and the fourth flight aircraft are intended primarily for testing avionics and the passenger cabin interior, including emergency evacuation. The same two aircraft will confirm the designed landing category and environmental noise level.

Upon completion of the factory flight test (from 10 to 40 flights depending on the aircraft), the aircraft, which are in the final assembly shop today, will in total make over 600 certification flights at SCAC's Zhukovsky-based flight test centre.

The test campaign intended to confirm the aircraft's readiness for the first flight included tests on the rigs. Similarly, the certification campaign includes tests on various rigs and on a number of SCAC's system and integration rigs of the static aircraft to confirm the designated life cycle of the aircraft.

Overall, SCAC together with the Programme suppliers will have to build over 40 test rigs. Indeed, the engineering simulator and the "Electronic bird" are entirely equipped and ready for the certification tests.

Besides, the static aircraft is being tested at TsAGI aiming to launch the Sukhoi Superjet 100 certification flight tests.

Customer and Fleet Support

SuperJet International SpA (SJI), founded in 2007 by Alenia Aeronautica and Sukhoi Company and responsible for worldwide Customer Services, will deliver Sukhoi Superjet 100 customer and fleet support. Customer services include:

- Spare Parts supply including AOG service

- Optional on-site spare parts lease stock

- Exchange pool for Line Replaceable Units (LRU)

- Off-wing maintenance of LRU's, and Main Elements (Landing Gear and APU) through a "one-window" concept

- Pool of high value tools and ground support equipment (GSE)

- Engineering Support

- Training

- Technical Publications, maintained and provided via Web, on CD/DVD, and in hardcopies

- Flight operations support

- Maintainability and reliability tracking & analysis

- On-Site Support by Field Service Representatives and Mobile Repair Teams

- Account Managers, coordinating all customer issues to ensure their overall satisfaction

SuperJet International will manage all these services through its "Customer Care Centre" as the focal contact point for customers available 24 hours 7 days a week via a user-friendly Web-Portal, phone or email .

Furthermore, SuperJet International offers "Super Care Plan (SCP)", with costs calculated on a "flight-hour" basis for the indicated services, selected from a menu, thus allowing the customer for guaranteed maintenance cost.

Aircraft base maintenance (A-,C,- and structural checks) is offered through a worldwide network of independent, reputable, SJI authorized Service Centres (aircraft MRO facilities). SJI will regularly support and audit these service centres on an ongoing basis to ensure OEM quality standards.

SJI offers LRU and Main Elements repair and overhaul through its "one-window" as a single interface, but subcontracts the job to vendors and component R&O facilities. However, the customer is free to contract LRU and Main Elements repair and overhaul direct to vendors or other service providers.

SJI's first Training Centres Organization will be located in two sites: Moscow and Venice. The first training equipment – Flight Navigation Procedure Training device – has already been installed in SJI's Venice Headquarters and the Training Class Room is ready. In May 2008 SJI had started its first training courses for internal staff – SSJ100 Maintenance General Familiarization. FTO (EASA) certification for the "temporary" Marcon training facility in Venice, is in progress.

As for SJI training facilities in Moscow, the use Sukhoi's facilities in Zhukovsky is being considered. Both classrooms and training devices, such as Full Flight Simulators (FFS), will be timely installed to support training. This facility will be further used to support training needs of all customers in Russia/CIS.

Prior to entry into service, SJI will provide the customers with Recommended Spare Parts List (RSPL) for initial provisioning, followed by initial provisioning conferences. Parts are delivered to the customer on the Purchase order well in time before arrival of the first aircraft. Subsequently, all spare parts orders, relating both to proprietary and vendor components, will be managed through the SJI Customer Care Center.

SJI will initially establish two main spare parts distribution centres, one in Moscow (early 2009) and one in ?entral Europe (early 2010), followed by additional warehouses located in other countries worldwide depending on the Sukhoi Superjet 100 market. All these centres will be managed by a leading international logistics provider.

SJI is currently selecting a Logistics Provider to manage the SuperJet International warehouse network and to provide all logistics services, such as transportation and customs clearance.

SJI is committed to have the Moscow warehouse (at SVO) ready in 2009, with initial spare parts provisioning starting no later than 2 months prior to first SSJ100 delivery to AFL.
