Narrative:
The WX was poor -- RVR 4500, rain, fog, 34 degrees. While flying the ILS to 9R at ord we noticed our inboard flaps jammed at 5 degrees. We initiated a missed approach and began running the abnormal procedure. ATC had asked us to speed up a couple of times to fit into traffic flow but due to the abnormal confign, we were unable. We also asked to maintain 4000 ft instead of 5000 ft but they were unable due to converging bases on simultaneous approachs to 9L and 9R. I was thoroughly impressed with ord approach. They were obliging and professional. They gave us a downwind vector and let us decide when we were ready to come back in. The approach and landing were uneventful. It ran just like the many times we practiced it in the simulator.

Title: ACR LGT ACFT'S FLAP JAMMED DURING APCH RESULTING IN A MISSED APCH AND SUBSEQUENT LNDG WITH PARTIAL FLAPS.
Narrative: THE WX WAS POOR -- RVR 4500, RAIN, FOG, 34 DEGS. WHILE FLYING THE ILS TO 9R AT ORD WE NOTICED OUR INBOARD FLAPS JAMMED AT 5 DEGS. WE INITIATED A MISSED APCH AND BEGAN RUNNING THE ABNORMAL PROC. ATC HAD ASKED US TO SPD UP A COUPLE OF TIMES TO FIT INTO TFC FLOW BUT DUE TO THE ABNORMAL CONFIGN, WE WERE UNABLE. WE ALSO ASKED TO MAINTAIN 4000 FT INSTEAD OF 5000 FT BUT THEY WERE UNABLE DUE TO CONVERGING BASES ON SIMULTANEOUS APCHS TO 9L AND 9R. I WAS THOROUGHLY IMPRESSED WITH ORD APCH. THEY WERE OBLIGING AND PROFESSIONAL. THEY GAVE US A DOWNWIND VECTOR AND LET US DECIDE WHEN WE WERE READY TO COME BACK IN. THE APCH AND LNDG WERE UNEVENTFUL. IT RAN JUST LIKE THE MANY TIMES WE PRACTICED IT IN THE SIMULATOR.
