Narrative:

On radar vectors and climb out from ontario airport en route to stl we received a TCASII RA at about 6500 MSL. Were cleared to 7000 ft MSL. The red RA alert was superimposed directly over our aircraft with no data tag. We looked up and ahead (no traffic), assumed possible traffic right under us and pulled up sharply and adding power. We went approximately 250 ft above our assigned 7000 ft before coming back quickly to 7000 ft. I told departure control we had an RA, had exceeded our assigned altitude by about 250 ft and were descending and level at 7000 ft. All they said was roger. I asked them if they had any traffic in that location and they said no. We assumed a false TCASII RA.

Title: TCASII RA CREATES AN ALTDEV ALT EXCURSION ALT OVERSHOT ON DEP PROC.

Narrative: ON RADAR VECTORS AND CLBOUT FROM ONTARIO ARPT ENRTE TO STL WE RECEIVED A TCASII RA AT ABOUT 6500 MSL. WERE CLRED TO 7000 FT MSL. THE RED RA ALERT WAS SUPERIMPOSED DIRECTLY OVER OUR ACFT WITH NO DATA TAG. WE LOOKED UP AND AHEAD (NO TFC), ASSUMED POSSIBLE TFC RIGHT UNDER US AND PULLED UP SHARPLY AND ADDING PWR. WE WENT APPROX 250 FT ABOVE OUR ASSIGNED 7000 FT BEFORE COMING BACK QUICKLY TO 7000 FT. I TOLD DEP CTL WE HAD AN RA, HAD EXCEEDED OUR ASSIGNED ALT BY ABOUT 250 FT AND WERE DSNDING AND LEVEL AT 7000 FT. ALL THEY SAID WAS ROGER. I ASKED THEM IF THEY HAD ANY TFC IN THAT LOCATION AND THEY SAID NO. WE ASSUMED A FALSE TCASII RA.
