On 29 August 2007, a SAAB Aircraft Company 340B-229 (SAAB) aircraft was being operated on a scheduled passenger service from Adelaide, SA to Mount Gambier. The aircraft departed from runway 05 soon after an Airbus A320-232 (Airbus) aircraft departed from the same runway. When the SAAB reached a height of 250 to 350 ft above ground level (AGL), the flight crew experienced abrupt, severe buffeting and an uncommanded roll to the left, followed by another roll to the right.
As a result of this occurrence, the aircraft operator advised that they reviewed their operating procedures relating to departures behind jet aircraft and will use the ATSB report as part of a safety promotion strategy directed at all company pilots. In addition, The Civil Aviation Safety Authority is reviewing the safety implications of this incident and is considering the development of a safety education program for flight crew and air traffic controllers.
