Accidents & Serious Incidents involving SF34

  • BE20/SF34, Vicinity Stornoway UK, 2011 (LB LOS HF) (On 31 December 2011 a USAF C12 Beech King Air descended 700 feet below the cleared outbound altitude on a procedural non precision approach to Stornoway in uncontrolled airspace in IMC and also failed to fly the procedure correctly. As a result it came into conflict with a Saab 340 inbound on the same procedure. The Investigation found that the C12 crew had interpreted the QNH given by ATC as 990 hPa as 29.90 inches, the subscale setting units used in the USA. The Saab 340 pilot saw the opposite direction traffic on TCAS and descended early to increase separation.)
  • SF34 / B190, Auckland NZ, 2007 (RI HF) (On 29 May 2007, a Saab 340 aircraft that was holding on an angled taxiway at Auckland International Airport was inadvertently cleared to line up in front of a landing Raytheon 1900D. The aerodrome controller transmitted an amended clearance, but the transmission crossed with that of the Saab crew reading back the line-up clearance. The pilots of both aircraft took action to avoid a collision and stopped on the runway without any damage or injury.)
  • SF34 / E145, Stockholm Sweden, 2002 (RI HF) (Description On 16 December 2002, a Saab 340 being operated by Swedish airline Skyways and arriving at Stockholm on a scheduled domestic passenger flight and an Embraer 145 being operated by Swiss on a scheduled passenger flight from Stockholm to Basel almost collided at the intersection between taxiways ‘Z’ and ‘A’ in normal night visibility. Upon seeing the Saab approaching on a conflicting track, the Embraer 145 was stopped very suddenly and the other aircraft passed within an estimated 3 metres. No persons were injured and neither aircraft was damaged. The diagram below taken from the official report shows the intersection involved.)
  • SF34, Izumo Japan, 2007 (HF RE) (On 10 December, 2007 a SAAB 340B being operated by Japan Air Commuter on a scheduled passenger flight left the runway at Izumo Airport during the daylight landing roll in normal visibility and continued further while veering to the right before coming to a stop on the airport apron.)
  • SF34, Kirkwall Orkney UK, 2003 (LOC GND) (On 12 September 2003, a Saab 340B being operated by UK regional airline Loganair on a scheduled passenger flight from Aberdeen to Kirkwall experienced a loss of pitch control during landing at destination and the rear fuselage contacted the runway causing damage to the airframe. Once the aircraft had cleared the runway, some passengers and some of the hold baggage was removed before the aircraft was taxied to its parking position because of a suspicion that the aircraft might have been loaded contrary to the accepted load and trim sheet.)
