Situational Awareness; Confusion
Aircraft Equipment Problem Less Severe; Deviation / Discrepancy - Procedural Published Material / Policy
Flight Crew Became Reoriented; Flight Crew Overcame Equipment Problem
Human Factors
After a normal landing; the flight control annunciator illuminated during taxi to gate. Looked up and both hydraulic B switches were off and engine heat was on. Turned hydraulic B switches on and engine heat off. I assume this occurred during after landing flow as there were no amber lights on during approach or with a master recall. Approach and landing felt normal.
While taxiing in; the Captain noticed the Feel Diff Press caution light was illuminated and the #2 hydraulic pressure was low. He then noticed that both #2 hydraulic pump switches were off. I believe that on my after-landing flow I reached up to turn off the engine anti-ice switches; but grabbed the hydraulic pump switches by mistake. When we turned on the hydraulic pumps; the caution light extinguished and the system operated normally. In my mind; there is a slight chance the pumps were turned off in flight; but this seems unlikely because I don't remember intending to turn off the anti-ice until after landing.My insufficient attention to detail in confirming the correct switches was the main cause of the problem. I had also forgotten to wait to do the after-landing flow until after crossing all runways with taxi instructions received and understood. I will remember from this event to wait until the appropriate time to perform procedures; and to always visually confirm every switch before moving it.
After a normal landing the flight control annunciator illuminated during taxi to gate. Upon checking the overhead both hydraulic B switches were found off and engine heat was on. The First Officer believes he may have made a mistake on the after landing flow.
