During the changing of a reserve part in the plane's landing gear a gasket was forgotten and later blocked a hydraulic arm, preventing the right wheel from emerging during the landing at Copenhagen's Kastrup Airport on Oct. 27, Danish newspaper Politiken reports.
A series of landing gear problems with this Dash model convinced SAS and subsidiary Widerøe to shelve its fleet of Q-400s, a decision that the manufacturer protested at the time.
According to Politiken, the accident investigation has also found that the equipment change occurred without producer Bombardier being notified by SAS.
Bombardier also said that the equipment shift did not follow accepted procedure, with SAS using a reserve part normally intended for the nosewheel.
SAS spokesman Bertil Ternert said that the airline group did not wish to comment at the time since the accident investigation board had not yet completed its work.
The European air safety organization EASA meets in Cologne on Wednesday to consider the lifting of the Scandinavian aviation authority ban on the Dash 8 Q-400, Danish news agency Ritzau reports.
