Narrative:
Upon gear retraction we had a master caution 'air.' I looked up at the air panel and saw a bleed leak for the #2 engine. Due to the fact that the #1 bleed was deferred we could not pressurize. While discussing whether to continue or return to dfw we exceeded our initial altitude of 2000 ft. The altitude deviation was caused by a minor distraction during the initial climb segment. While this altitude deviation was caused by crew error, I firmly believe it could have been avoided if ATC at dfw did not give all propeller driven aircraft an initial altitude of 2000 ft. In light of the fact that the ATR-72 climbs out at better than 3000 FPM initially, it seems that an initial altitude of 5000 ft would be more appropriate.

DUE TO THE FACT THAT THE #1 BLEED WAS DEFERRED WE COULD NOT PRESSURIZE. WHILE DISCUSSING WHETHER TO CONTINUE OR RETURN TO DFW WE EXCEEDED OUR INITIAL ALT OF 2000 FT. THE ALTDEV WAS CAUSED BY A MINOR DISTR DURING THE INITIAL CLB SEGMENT. WHILE THIS ALTDEV WAS CAUSED BY CREW ERROR, I FIRMLY BELIEVE IT COULD HAVE BEEN AVOIDED IF ATC AT DFW DID NOT GIVE ALL PROP DRIVEN ACFT AN INITIAL ALT OF 2000 FT. IN LIGHT OF THE FACT THAT THE ATR-72 CLBS OUT AT BETTER THAN 3000 FPM INITIALLY, IT SEEMS THAT AN INITIAL ALT OF 5000 FT WOULD BE MORE APPROPRIATE.
