A crash-landing by a Dash 8 Q400 turboprob plane flown by SAS on Oct. 27 could have been caused by earlier maintenance, a preliminary report by Danish authorities said.
The report, issued over the weekend and obtained by Reuters on Monday, said a blockage could have caused the right-side main landing gear on the plane to fail to extend properly.
The incident, which occurred as the plane was landing at Copenhagen's Kastrup airport, was the third such accident involving a Q400 turboprop plane operated by the Scandinavian airline within two months.
No one was seriously injured in any of the incidents.
The report, by the Danish Accident Investigation Board, said a valve in the landing gear was blocked by a part from a separate valve.
It said that during the replacement of one valve on Oct. 22, "the rogue O-Ring found blocking the orifice in the restrictor valve of the accident aircraft could have unknowingly been transferred by maintenance personnel".
It said the investigation was continuing.
SAS declined to comment. |
