Narrative:

Flight X was from fll to iah. On departure from fll, we were cleared to fly runway heading and maintain 3000 ft, on the fll 8 departure. Shortly after takeoff, we were cleared to continue our climb and to maintain runway heading (270 degrees). Our next clearance was to make a hard right turn to 040 degrees. Next we were told to immediately stop our climb, which we did at 6000 ft. After we broke out of the clouds we saw the other after (Y) to our left at our altitude. Its horizontal distance was not determined. We are not sure how the 2 aircraft got so close. We think that the other act missed a clearance due to the controller's instructions being stepped on by other aircraft.

Original NASA ASRS Text

Title: MIA CTLR ISSUES TURNS AND ALT CHANGE ON B737 APPARENTLY TO REMAIN CLR OF ANOTHER ACFT WHO FAILED TO ADHERE TO CTLR INSTRUCTIONS.

Narrative: FLT X WAS FROM FLL TO IAH. ON DEP FROM FLL, WE WERE CLRED TO FLY RWY HDG AND MAINTAIN 3000 FT, ON THE FLL 8 DEP. SHORTLY AFTER TKOF, WE WERE CLRED TO CONTINUE OUR CLB AND TO MAINTAIN RWY HDG (270 DEGS). OUR NEXT CLRNC WAS TO MAKE A HARD R TURN TO 040 DEGS. NEXT WE WERE TOLD TO IMMEDIATELY STOP OUR CLB, WHICH WE DID AT 6000 FT. AFTER WE BROKE OUT OF THE CLOUDS WE SAW THE OTHER AFTER (Y) TO OUR L AT OUR ALT. ITS HORIZ DISTANCE WAS NOT DETERMINED. WE ARE NOT SURE HOW THE 2 ACFT GOT SO CLOSE. WE THINK THAT THE OTHER ACT MISSED A CLRNC DUE TO THE CTLR'S INSTRUCTIONS BEING STEPPED ON BY OTHER ACFT.
