Synopsis
EMB 145 flight crew reported a 'flap fail' caution message during landing phase. Crew landed safely.
Narrative
On arrival into ZZZ on Runway XX; at approximately 1600ft AGL I called for flaps 45 and the landing checklist. As the FO selected flaps 45; we received a flap low speed" advisory message followed thereafter by a "flap fail" caution message. We noticed the flaps were set to 27 degrees on the eicas and verified on the rmu engine page. We had already ran landing data and had appropriate numbers for a flaps 22 landing on runway XX; so this allowed us to continue to land on the runway as the QRH says to multiply unfactored landing distance by 1.4 for flaps 22-44 degrees selected so this turned out to be less required runway distance than the numbers we ran initially. The FO and I agreed it was not necessary to conduct a go around and we landed safely on the runway. Upon exiting the runway and taxiing to our gate; we were not able to retract the flaps back to 0. When we arrived at the gate and the passengers were deplaned I called Maintenance to inform them of the issue and wrote it up appropriately in the log book.This aircraft had this same previous issue the day prior and an evaluation check was conducted on it and was passed."
Second reporter narrative
During arrival to ZZZ on Runway XX; the captain called for flaps 45; landing checklist. I selected flaps 45 and we got a flap low speed"; followed by a "flap fail" caution message. The EICAS indicated 27 degrees. Since we ran the numbers for both flaps settings; I quickly changed the Vref to flaps 22. The Captain and I concurred that we exceeded landing performance required in the QRH and continued to a normal landing. When we cleared 35; during after landing flow; we discovered the flaps would not retract. During my post flight walk around; flaps were stuck at 27 degrees.Failure to diagnose/troubleshoot root cause initially.Suggestion: A more extensive evaluation flight to include multiple TO & LDG's before release to service."
