Description

Turboprop regional airliner. In service since 1994. Stretched, more powerful development of SAAB 340 regional airliner. First civil aircraft powered by Allison AE-2100A turboprops (developed for the V-22 Osprey tiltrotor). Cabin noise is reduced by an active noise control system with 72 microphones and 36 speakers which generate an anti-phase noise. 56 aircraft were built until 1998 and production then ceased.

Accidents & Serious Incidents involving SB20

  • D328 / SB20, London City UK, 1999 (On 15 April 1999, a Dornier 328 crossed the holding point while a Saab 2000 was decelerating after landing on the same runway and the separation between the two aircraft was reduced to 10 meters as the landing aircraft passed. The runway incursion was subsequently attributed to distraction.)
  • SB20 / C510, vicinity Lugano Switzerland, 2011 (On 16 December 2011, a Saab 2000 in the hold and an opposite direction Cessna VLJ joining it lost procedural separation in IMC near Lugano due to conflicting ATC clearances issued by the same controller who had used the wrong Transition Level. Any risk of collision was removed by a TCAS RA activated on the Saab 2000 but the Investigation found that the DFTI radar display available to the controller to help resolve unexpected emergency situations was configured to systematically convert SSR standard pressure altitudes to QNH for altitude display using a distant and inappropriate value of QNH.)
  • SB20, Stockholm Arlanda, 2001 (On 18 December 2001, a Saab 2000 being operated by Air Botnia on scheduled passenger flight from Stockholm to Oulu was taxiing out at night in normal visibility in accordance with its ATC clearance when a car appeared from the left on a roadway and drove at speed on a collision course with the aircraft. In order to avoid a collision, the aircraft had to brake sharply and the aircraft commander saw the car pass under the nose of the aircraft and judged the vehicle’s closest distance to the aircraft to be four to five metres. The car did not stop, could not subsequently be identified and no report was made by the driver or other witnesses. The diagram below taken from the official report shows the site of the conflict - the aircraft was emerging from Ramp ‘G’ to turn left on taxiway ‘Z’ and the broken line shows the roadway which is crossed just before the left turn is commenced.)
  • SB20, Werneuchen Germany, 2002 (On 10 July 2002, a Saab 2000 being operated by Swiss Air Lines on a scheduled public transport service from Basel to Hamburg encountered extensive thunderstorms affecting both the intended destination and the standard alternates and due to a shortage of fuel completed the flight with a landing in day VMC at an unmanned general aviation airstrip where the aircraft collided with an unseen obstruction. After the aircraft came to a stop with the landing gear torn off, the two cabin crew conducted the passenger evacuation on their own initiative. There was no fire and only one of the 20 occupants was injured. The aircraft was declared a hull loss due to the damage sustained relative to the location.)
  • SB20, vicinity Sumburgh, UK 2014 (On 15 December 2014, the Captain of a Saab 2000 lost control of his serviceable aircraft after a lightning strike when he attempted to control the aircraft manually without first disconnecting the autopilot and despite the annunciation of a series of related alerts. The aircraft descended from 4,000 feet to 1,100 feet at up to 9,500 fpm and 80 knots above Vmo. A fortuitous transient data transmission fault caused autopilot disconnection making it possible to respond to EGPWS 'SINK RATE' and 'PULL UP' Warnings. The Investigation concluded that limitations on autopilot disconnection by pilot override were contrary to the type certification of most other transport aircraft.)
