Scandinavian Airlines Flight 1209, a de Havilland Canada Dash-8-400, took off from Copenhagen Airport, Denmark, on September 9 2007. It was headed to Aalborg Airport, Denmark. SK1209 is a code-shared flight with Spanair flight JK9101, BMI flight BD3923 and Lufthansa flight LH6002.
The landing gear failed prior to landing and the crew circled for an hour before attempting an prepared emergency landing. Upon touchdown, the right landing gear collapsed and the right wing touched ground and a fire broke out. The fire was extinguished by airport emergency teams and all passengers and crew was evacuated. Five people suffered minor injuries, some from propeller parts entering the cabin and some from the evacuation.
Investigation
When activating the handle for lowering the landing gear, the indicator showed two green and one red light. The red light indicated that right landing gear was not locked in position. The landing was aborted. Manual lowering of the landing was attempted also with negative result. Investigation focused on right landing gear. The main landing gear hydraulics actuator top eyebolt was separated from the actuator. A further analysis of the actuator shows corrosion on the inside leading to reduced mechanical strength of the actuator and eventually failure. [1]
On September 19 2007 the prosecutor of Stockholm has commenced a preliminary investigation regarding suspicion of creating danger to another person. [2]
Maintenance procedures
Scandinavian Airlines System (SAS) has been accused of cutting corners for maintenance. As the Civil Aviation Administration began an investigation of the accident, it brought renewed focus on SAS maintenance procedures. Only two weeks previously, Swedish authorities had levelled a scathing critique at the airline after a plane of the same model nearly crashed because its motor accelerated unexpectedly during landing. The airline reportedly made 2,300 flights in which safety equipment was not up to standard, but it has denied that it failed to live up to safety standards.[3]
Similar incidents with Dash 8
- In 2002 a wheel detached from the starboard side of the undercarriage at an aircraft owned by Tyrolean Airways while taking off from Frankfurt Airport. The missing wheel was detected after landing in Salzburg Airport, and the wheel was later recovered.[4]
- In 2004, an All Nippon Airways flight made an emergency landing with a failure of the right landing gear at Kōchi Ryōma Airport.
- On 13 March 2007, All Nippon Airways Flight 1603, nose-landed safely at Kōchi Ryōma Airport after the front wheel of the plane failed to deploy. Bombardier advised all operators to inspect the nose landing-gear mechanism of the aircraft. See also: All Nippon Airways[5]

- On September 12 2007, SAS flight SK2748 with 48 passengers and four crew members was on flight to Palanga, Lithuania when problems with the main landing gear was identified. The pilots were forced to make an emergency landing at Vilnius Airport. After landing the right gear collapsed.
- On September 14 2007, Lufthansa Flight LH4076 (tail number D-ADHA) with 68 passengers and four crew members was on flight to Florence, Italy when problems with the front landing gear was identified.
