Narrative:

Departed for XXX following normal preflight and taxi. First officer's leg. Climbing through 8000 ft in IMC, we received a bleed 2 leak. Decided to return to ord after running appropriate checklists. I took my landing weight off of the performance page of the FMS. It was wrong, but I did not catch it. First officer flew until we were on the approach. I did the landing. I estimated about 150 FPM sink at touchdown. Debriefed maintenance at gate while crew and passenger moved to new airplane. Dispatch asked if I landed overweight. I said no. I believed that. During subsequent flight, I began to doubt my belief. Upon return to ord, I went to maintenance and checked on the landing fuel. Doing the math from memory, I am sure we were overweight -- 1500-2000 pounds. I then wrote the jet up for an overweight landing. Aircraft had not flown again.

Title: E145 FLT CREW INADVERTENTLY LAND OVERWT FOLLOWING DISCOVERY OF A BLEED AIR LEAK SOON AFTER DEP FROM ORD.

Narrative: DEPARTED FOR XXX FOLLOWING NORMAL PREFLT AND TAXI. FO'S LEG. CLBING THROUGH 8000 FT IN IMC, WE RECEIVED A BLEED 2 LEAK. DECIDED TO RETURN TO ORD AFTER RUNNING APPROPRIATE CHKLISTS. I TOOK MY LNDG WT OFF OF THE PERFORMANCE PAGE OF THE FMS. IT WAS WRONG, BUT I DID NOT CATCH IT. FO FLEW UNTIL WE WERE ON THE APCH. I DID THE LNDG. I ESTIMATED ABOUT 150 FPM SINK AT TOUCHDOWN. DEBRIEFED MAINT AT GATE WHILE CREW AND PAX MOVED TO NEW AIRPLANE. DISPATCH ASKED IF I LANDED OVERWT. I SAID NO. I BELIEVED THAT. DURING SUBSEQUENT FLT, I BEGAN TO DOUBT MY BELIEF. UPON RETURN TO ORD, I WENT TO MAINT AND CHKED ON THE LNDG FUEL. DOING THE MATH FROM MEMORY, I AM SURE WE WERE OVERWT -- 1500-2000 LBS. I THEN WROTE THE JET UP FOR AN OVERWT LNDG. ACFT HAD NOT FLOWN AGAIN.
