Narrative:

We were on a vector to runway 26 in phx. We were very high and close. Approach control asked if we saw the runway, we said we did. They then cleared us for the visual. We should have gone around at that point. We tried to make approach work. We were configured before 1000 ft AGL. About the time we crossed the approach lights, I noticed that the flaps were at 25 degrees. The flap handle was at 30 degrees, but the flaps indicated 25 degrees. We executed a go around. I don't know where in the approach the flaps blew up to 25 degrees. When I scanned the airspeed on the approach, it was always below maximum flap speed. Our landing weight was near maximum landing weight.

Title: GAR PERFORMED BY THE PIC OF A B737 AFTER A DESTABILIZED APCH FOR RWY 26 AT PHX, AZ.

Narrative: WE WERE ON A VECTOR TO RWY 26 IN PHX. WE WERE VERY HIGH AND CLOSE. APCH CTL ASKED IF WE SAW THE RWY, WE SAID WE DID. THEY THEN CLRED US FOR THE VISUAL. WE SHOULD HAVE GONE AROUND AT THAT POINT. WE TRIED TO MAKE APCH WORK. WE WERE CONFIGURED BEFORE 1000 FT AGL. ABOUT THE TIME WE CROSSED THE APCH LIGHTS, I NOTICED THAT THE FLAPS WERE AT 25 DEGS. THE FLAP HANDLE WAS AT 30 DEGS, BUT THE FLAPS INDICATED 25 DEGS. WE EXECUTED A GAR. I DON'T KNOW WHERE IN THE APCH THE FLAPS BLEW UP TO 25 DEGS. WHEN I SCANNED THE AIRSPD ON THE APCH, IT WAS ALWAYS BELOW MAX FLAP SPD. OUR LNDG WT WAS NEAR MAX LNDG WT.
