Narrative:
On climb out after takeoff we were assigned a heading of 210 degrees. Upon changeover to departure, we were directed to continue our climb to 14000 ft. We then received a TA on our TCASII for climbing traffic in front of us. He was co-altitude and approximately 1/2 mi away. We continued our climb and passed 300 ft above them. When we notified ATC, they replied with a 'weren't you cleared to intercept the departure?' ATC stopped aircraft #2's climb. (We had deviated from heading to insure avoidance.) I believe 2 things contributed. 1) apparently we received a nonstandard clearance/handoff between controllers. 2) the cargo aircraft did not have TCASII and was unaware of our position and the potential hazard.
Original NASA ASRS Text
Title: AN ACR B737-200 FLC HAD A CONFLICT WITH AN ACR B727 FREIGHTER DUE TO AN INTERFAC COORD PROB BTWN THE TWR AND TRACON.
Narrative: ON CLBOUT AFTER TKOF WE WERE ASSIGNED A HDG OF 210 DEGS. UPON CHANGEOVER TO DEP, WE WERE DIRECTED TO CONTINUE OUR CLB TO 14000 FT. WE THEN RECEIVED A TA ON OUR TCASII FOR CLBING TFC IN FRONT OF US. HE WAS CO-ALT AND APPROX 1/2 MI AWAY. WE CONTINUED OUR CLB AND PASSED 300 FT ABOVE THEM. WHEN WE NOTIFIED ATC, THEY REPLIED WITH A 'WEREN'T YOU CLRED TO INTERCEPT THE DEP?' ATC STOPPED ACFT #2'S CLB. (WE HAD DEVIATED FROM HDG TO INSURE AVOIDANCE.) I BELIEVE 2 THINGS CONTRIBUTED. 1) APPARENTLY WE RECEIVED A NONSTANDARD CLRNC/HDOF BTWN CTLRS. 2) THE CARGO ACFT DID NOT HAVE TCASII AND WAS UNAWARE OF OUR POS AND THE POTENTIAL HAZARD.
