Narrative:

On final approach to ZZZ; flaps fail EICAS message illuminated when flaps were selected. A missed approach and a climb away from the traffic pattern was initiated for vectors to assess the problem and run the QRH. Control was with ZZZ approach. QRH procedure was accomplished and we were handed off to tower but were too high and too fast to complete a no flap landing from that point. A go around was accomplished to the VFR traffic pattern and an uneventful no flap landing was accomplished.

Title: CL604 FLT CREW REPORTS FLAPS FAIL EICAS DURING APPROACH. MISSED APCH AND QRH PROCEDURES LEAD TO NO FLAP APCH AND GAR DUE TO HIGH AND FAST. THIRD ATTEMPT SUCCESSFUL.

Narrative: ON FINAL APCH TO ZZZ; FLAPS FAIL EICAS MESSAGE ILLUMINATED WHEN FLAPS WERE SELECTED. A MISSED APCH AND A CLB AWAY FROM THE TFC PATTERN WAS INITIATED FOR VECTORS TO ASSESS THE PROB AND RUN THE QRH. CTL WAS WITH ZZZ APCH. QRH PROC WAS ACCOMPLISHED AND WE WERE HANDED OFF TO TWR BUT WERE TOO HIGH AND TOO FAST TO COMPLETE A NO FLAP LNDG FROM THAT POINT. A GAR WAS ACCOMPLISHED TO THE VFR TFC PATTERN AND AN UNEVENTFUL NO FLAP LNDG WAS ACCOMPLISHED.
