I read in today´s ATW Daily News concerning the main landing gear:
SAS technical Dpt has found problems in 63 % of the SSV valves on the grounded Q400s.
"The SSV valve has a construction error and is currently being modified by the supplier", SAS concluded.
I take it SAS means Goodrich is modifying the valve design. While this probably is not "a major design flaw in the aircraft", surely this, if true, means that not everything can be blamed on SAS maintenance?
