B767-200 EICAS Wing Hydraulic Valve message
Recently had EICAS message "Wing Hydraulic Valve" message appear in flight. A scenario I thought was confined to the ground.
Anyone else experienced this?

Flight Control Wing Valve
There apparently is an EICAS advisory message for L WING HYD VAL or R WING HYD VAL. This advisory apparently indicates the left or right wing hydraulic flight control valve is closed. It would be interesting to see the indications on the P61 panel.
The MEL discusses how to dispatch with the valve secured into the open position. It would be a lengthy maintenance procedure.

The DDG says the valve may be inoperative open, with maintenance action as follows -
Verify associated valve (s) is open by pressurizing the appropriate hydraulic system and displacing control column or control wheel, as appropriate, while observing flight control deflection on EICAS.
Given the nature of the snag, I would rather opt for manual postioning of valve, removal and stowage of plug and then testing as above.
