Narrative:
Flight was level at 11000, approach downwind, when approach control issued traffic -- 2 fgts climbing sbound, cleared to 10000 ft. First officer (PF) saw traffic and, at the same time, TCASII issued first a TA, then an RA. Our TCASII showed the fgt leveling at 11200. They passed 2-3 mi in front of us. We saw traffic the whole time and did not take evasive action. Had we been IMC and/or 2-3 mi ahead, the story might have had a different ending, for TCASII told us to climb. Comments: 1) I spoke to the tower chief shortly after landing, and he concurred that the fgt violated our airspace by not adhering to their clearance. 2) following an RA could have caused us to climb into the traffic. Apparently he (they) mistook his clearance to 10000 for 11000. Supplemental information from acn 258535: immediately after takeoff on runway 08 abq IAP, switched from tower to departure. Instructed right turn 160 degrees, climb to 10000 ft. Shortly thereafter, fgt experienced a ground collision warning. Pilot snapped nose up, checked terrain (less than 1 mi away). Topped out at 11000 ft, immediately descended back to 10000 ft. Reset electrical system and continued. We had the airliner in sight at all times, did not feel there was a conflict. After landing, fgt was determined to have been experiencing false warnings due to radar altimeter bus failure.

Title: CONFLICT WITH FGT WHO OVERSHOT ALT ACCOUNT FALSE GPWS.
Narrative: FLT WAS LEVEL AT 11000, APCH DOWNWIND, WHEN APCH CTL ISSUED TFC -- 2 FGTS CLBING SBOUND, CLRED TO 10000 FT. FO (PF) SAW TFC AND, AT THE SAME TIME, TCASII ISSUED FIRST A TA, THEN AN RA. OUR TCASII SHOWED THE FGT LEVELING AT 11200. THEY PASSED 2-3 MI IN FRONT OF US. WE SAW TFC THE WHOLE TIME AND DID NOT TAKE EVASIVE ACTION. HAD WE BEEN IMC AND/OR 2-3 MI AHEAD, THE STORY MIGHT HAVE HAD A DIFFERENT ENDING, FOR TCASII TOLD US TO CLB. COMMENTS: 1) I SPOKE TO THE TWR CHIEF SHORTLY AFTER LNDG, AND HE CONCURRED THAT THE FGT VIOLATED OUR AIRSPACE BY NOT ADHERING TO THEIR CLRNC. 2) FOLLOWING AN RA COULD HAVE CAUSED US TO CLB INTO THE TFC. APPARENTLY HE (THEY) MISTOOK HIS CLRNC TO 10000 FOR 11000. SUPPLEMENTAL INFO FROM ACN 258535: IMMEDIATELY AFTER TKOF ON RWY 08 ABQ IAP, SWITCHED FROM TWR TO DEP. INSTRUCTED R TURN 160 DEGS, CLB TO 10000 FT. SHORTLY THEREAFTER, FGT EXPERIENCED A GND COLLISION WARNING. PLT SNAPPED NOSE UP, CHKED TERRAIN (LESS THAN 1 MI AWAY). TOPPED OUT AT 11000 FT, IMMEDIATELY DSNDED BACK TO 10000 FT. RESET ELECTRICAL SYS AND CONTINUED. WE HAD THE AIRLINER IN SIGHT AT ALL TIMES, DID NOT FEEL THERE WAS A CONFLICT. AFTER LNDG, FGT WAS DETERMINED TO HAVE BEEN EXPERIENCING FALSE WARNINGS DUE TO RADAR ALTIMETER BUS FAILURE.
