Synopsis
Embraer 145 flight crew reported hydraulic system failure during climb resulted in return to departure airport.
Narrative
CA was PM and FO was PFDeparting from XXL climbing to 3000 departure had us climb to 5000 and frequency change to another departure controller. CA checks in and gets clearance to climb to 9000. Climbing around 6000ft we get a HYD1 LO QTY EICAS msg. CA checks the hydraulic page and sees that quantity is in the amber however pressure is holding steady at 2900PSI. Then CA pulls out Hydraulic System Low Quantity and followed QRH that referenced to Hydraulic System 1 Failure. At this point the pressure starts to slowly drop from system one and soon get aileron and rudder system 1 fail followed by hydraulic system 1 fail. Also hear the nose gear door drop and made sure we did not go above 250kts. CA lets ATC know that we have a hydraulic system failure and will be needing to return back to ZZZ. CA advises downwind leg (for the south runways) while crew runs checklist. After QRH; CA notifies dispatch about HYD SYS1 fail via ACARS; gives special procedures to FA and a PA to pax (Passengers). CA runs through Checklists and verifies landing weight below max ldg limit. In the mean time ATC gives us fixes of ZZZZZ followed by ZZZZZ1 for navigation. Approach control advises if we can accept a 10 mile base and XXR which the crew accepts as sufficient time. Before turning base leg; crew swap controls and CA becomes PF and FO becomes PM. Base leg turn we followed the rest of the QRH with free fall lever and landing gear lever and made sure we had 3 green ldg gear down. Crew gets cleared for the visual for XXR and normal callouts after that. We also advised tower control we will be needing a tug. Landed and taxied off Taxiway 1 and came to a stop. ARFF (Airport Rescue and Firefighting) meets the aircraft and communicate with crew on specified frequency. We did the after landing checklist. Then turned on APU and shutdown both engines per fire commands request as the fire crew did a 360 around the aircraft. After some time; tug came and tug us to Gate XX and from there we swapped to another aircraft.
Second reporter narrative
We departed XXL from ZZZ; I was PF and captain PM. Around 5000 Ft the captain noticed EICAS message HYD1 LO QTY. He reviewed the hydraulics system page and noticed the quantity decreasing but holding the pressure. Captain ran through the QRH for the appropriate EICAS message. As he was going through that; we lost all pressure and received aileron and rudder system 1 failed followed by hydraulic system 1 fail. PM ran through the QRH for the hydraulic system 1 fail. We were cleared to fly to 9;000 during this time and the captain notified ATC of the system fail and that we needed to return to ZZZ. ATC assigned us two GPS fixes and altitude to return to the field. Once all appropriate checklists and QRH items were completed. Capt and FO switched controls on the downwind for XXR. To setup for landing FO finished the remaining items in the QRH; by extending the emergency gear lever and landing checklist. Capt landed on XXR and exited the runway at Taxiway 1 coming to a full stop. From there Fire approached the AC (Aircraft) and inspected it. Eventually operations towed the plane to the gate.
