EMB-145 Flight Crew reported the failure of the HS 1 bleed valve. The pilots stated they ran the QRH, descended to a lower altitude, realized there was not enough fuel to complete the mission at the lower altitude and diverted. The pilots were in communication with their Dispatcher.

What is ASRS?

The Aviation Safety Reporting System is NASA's voluntary, confidential, non- punitive incident-reporting system, established 1976. Pilots, controllers, dispatchers, and maintenance technicians file reports describing safety- relevant events. NASA de-identifies every report before adding it to the public database. Reports are not investigated by NASA, the FAA, or the NTSB — they represent the reporter's perspective.

Pilot narratives

Verbatim from the de-identified NASA record. First-person account by the reporter. NASA strips identifying details (names, company, specific time); anonymization placeholders are ZZZ, X, Y.

Reporter 1

After takeoff from ZZZ1 we had caution indication on EICAS High Stage Valve We are followed QRH. We stayed at 25,000 feet and had two issues to resolve first the fault and secondly FO (First Officer) Display which blinked relevant report. We were in contact with the Dispatcher who after informing him about the current situation sent us our latest fuel calculations and informed us that we should go to the ZZZ as divert airport. We Indeed they did go to the Divert Airport ZZZ and I immediately contacted him after landing and ask new information for the next flight ZZZ-ZZZ2. I contacted with Maintenance and informing him about the two remarks by filling in technical log book.

Reporter 2

In flight on the way from ZZZ to ZZZ1, EICAS message HS 1 Valve Fail came up. We ran the QRH procedure and diagnosed the problem. The message came back up on the EICAS shortly after so we ran the procedure again and it was diagnosed but then shortly after once again, the message came back up on the EICAS. We ran the QRH procedure differently this time and we shut bleed valve 1 off. We were limited to FL250 when we were originally planned for FL360. We sent for fuel numbers and it was determined by both Dispatch and the crew to divert to ZZZ due to a higher fuel burn and with a maintenance issue.
