Synopsis

ERJ 145 flight crew reported an advisory HYD1 Low Quantity Message; followed by a ENG1 HYD Pump Fail message. After communicating with Maintenance; the flight crew elected to return to the departure airport where; during the approach; additional hydraulic system messages appeared. The crew completed a safe landing and noted leaking hydraulic fluid on the post flight walk around.

Narrative

We got an Advisory HYD1 Low Quantity Message. ENG1 HYD Pump FAIL then came on. [The Captain] took over the radios for me to pull the QRH. Upon going through the QRH; it was listed as a Crew Awareness. [The Captain] then decided we should get in contact with Control. They transferred the airplane and radios to me and called Control. Control asked us to turn back around to ZZZ so we advised Center that we needed to stop our climb at FL240 and turn around to ZZZ. We gave them our fuel and souls on board. Center gave us vectors and altitudes to join the ZZZZZ arrival. [The Captain] flew the airplane and ran the radios while I got our approach numbers for flaps from the QRH and ran through the descent/approach checklist. ZZZ eventually took us off the arrival and vectored us in for the visual XL. We informed Tower that we may need a tug to turn off on the taxiway; as we were unsure if we were going to have steering capabilities once off the runway. They informed us that per procedure; they were going to have the trucks waiting for us. As we began the approach for XL; and put the landing gear down; we got HYD SYS 1 FAIL and AIL SYS 1 INOP. We continued on the approach and [The Captain] landed the aircraft. On landing we got a RUDDER SYS 1 INOP; and. SPOILER FAIL. [The Captain] was able to successfully steer off the airplane and we got a HOT BRAKES indication as well. I went to the Hydraulics page; the Inboard Brakes were hot so we advised Ground of this as well.

Second reporter narrative

On climb out around 13;000 ft; HYD1 LOW QTY EICAS Message displayed. I checked on the Multi-function Flight Display (MFD) Hydraulics page to verify and Quantity showed 0 and in Amber. Shortly after E1 HYD PUMP FAIL EICAS Message appeared. I took over radios and First Officer (FO) ran QRH which just said 'Crew Awareness'. We continued the climb and got in touch with Maintenance who advised us to return to ZZZ. We told Center that we needed to stop the climb; and return to ZZZ. We had passengers and 9200 lbs. of fuel (4 hrs. of flight time.) I told the Flight Attendant about the issue and that we would be returning back to ZZZ. They stated that there was a loud whooshing sound. After that I let the passengers know about what was going on and apologized while reassuring we were completely safe. We were given a few vectors in the descent and given direct ZZZZZ for the ZZZZZ arrival. Approach asked if we needed assistance. We advised that we possibly might need help getting off the runway and taxi in since HYD 1 controls our Nose Wheel Steering. At this point they said they would have trucks standing by. I informed the Flight Attendant and passengers about the information and not to be alarmed. On approach HYD SYS 1 FAIL and AIL SYS 1 FAIL. During rollout of landing; SPOILER FAIL; RUDDER SYS 1 FAIL. Taxied off the runway and to the ramp. Got a HOT BRAKES indication due to only the inboard brakes being used and informed ground since the trucks were next to us. On post flight walk around; noticeable Hydraulic Fluid leaking from Engine 1 and on tail of aircraft.
