Sukhoi Superjet 100-95

Aeroflot - Russian International Airlines

The aircraft departed runway 24C at Moscow-Sheremetyevo Airport at 1803LT on a schedule service to Murmansk. Few minutes after takeoff, while climbing to an altitude of 10,000 feet, the crew encountered problems with the electrical system and informed ATC about an emergency situation via the transponder codes 7700 because communication systems were unserviceable. The crew initiated a circuit to return to the airport, continued the approach to runway 24L. On approach at an altitude between 900 and 1,100 feet, the windshear warning system sounded five times 'Go around. Windshear ahead'. From a height of 80 m (260 ft) above ground level, the aircraft descended below the glide path and at a height of 55 m (180 ft) the TAWS warning sounded: "Glide Slope." From that moment on the airspeed increased to 170 knots. At 18:30 the aircraft overflew the runway threshold and touched down at a distance of 900 m past the threshold at a speed of 158 knots. Touchdown occurred at a g-force of at least 2.55g with a subsequent bounce to a height of about 2 m. After two seconds the aircraft landed again on the nose landing gear with a vertical load 5.85g, and bounced to a height of 6 m. The third landing of the aircraft occurred at a speed of 140 knots with a vertical overload of at least 5g. This caused a rupture of the wing structure and fuel lines. The aircraft caught fire, went out of control, veered off runway to the right and came to rest in a grassy area, bursting into flames. The aircraft was destroyed by fire. 37 occupants were evacuated while 41 people, among them a crew member, were killed.

Yakutia Airlines

Following an uneventful flight from Ulan-Ude, the crew initiated the approach to Yakutsk-Platon Oyunsky Intl Airport Runway 23L. Due to work in progress, the runway 05R threshold was displaced by 1,150 metres, reducing the landing distance to 2,248 metres for the runway 23L on which the touchdown zone lighting system was unserviceable. On approach, the crew was informed by ATC that the friction coefficient was 0,45. The crew completed the landing on runway 23L with a slight tailwind component of 4 knots and started the braking procedure. Unable to stop within the remaining distance, the aircraft overran, entered the construction area and collided with the junction of a concrete section under reconstruction, causing both main landing gear to collapse (the left main gear was torn off). The aircraft slid for another 250 metres before coming to rest. All 92 occupants evacuated safely and the aircraft was damaged beyond repair.

Sukhoï

Aircraft was performing a demo flight and left Jakarta-Halim Perdanakasuma Airport at 1400LT with 41 passengers (potential buyers) on board and a crew of four. About thirty minutes later, while turning around Mount Salak, pilots received the authorization to descend from 10,000 feet to 6,000 feet in low visibility. Aircraft hit the edge of a cliff and crashed few yards further and was totally destroyed by impact and post impact fire. SAR teams arrived on scene 18 hours later and all 45 occupants were killed. At the time of the accident, weather conditions were marginal with clouds shrouding both Mount Salak and Mount Gede. First accident involving a Sukhoi Superjet 100. Present model was manufactured 09AUG2009 and totalized 843 flying hours for 500 cycles. Captain had 10,347 flying hours and was a test pilot by Sukhoi Civil Aircraft Company.
