Bombardier CRJ100ER, F-GRJO
The aircraft suffered a failure of the No 3 hydraulic system when lowering the landing gear on approach. The commander took what he believed to be the necessary actions prior to landing but without apparent reference to the QRH. As a result the aircraft landed with one of the No 3 hydraulic system pumps still running and the nosewheel steering ON, contrary to instructions in the Quick Reference Handbook (QRH). This resulted in an uncommanded steering input to the right after touchdown and the aircraft departed the runway.
