Narrative:

We were cleared for takeoff on runway 19L. After rotation the first officer noticed a helicopter ahead and to our right (approximately 1 O'clock), and headed eastbound. The first officer called the traffic to my attention (which was obscured by windshield post) and we opted to begin a shallow left turn to provide separation from the traffic (since we were unaware of his intentions with respect to route of flight). The tower made no mention of the traffic. We called the tower and he (controller) apologized saying the helicopter had overshot his departure gate and he (the controller) had not seen the conflict in time to issue an advisory. As always, alertness in the terminal area is crucial and adherence to an assigned departure is a must unless circumstances prohibit doing so safely. This report has been read and submitted as a crew effort by the captain and first officer--thus only 1 copy is being submitted.

Title: NMAC.

Narrative: WE WERE CLRED FOR TKOF ON RWY 19L. AFTER ROTATION THE FO NOTICED A HELI AHEAD AND TO OUR R (APPROX 1 O'CLOCK), AND HEADED EBOUND. THE FO CALLED THE TFC TO MY ATTN (WHICH WAS OBSCURED BY WINDSHIELD POST) AND WE OPTED TO BEGIN A SHALLOW L TURN TO PROVIDE SEPARATION FROM THE TFC (SINCE WE WERE UNAWARE OF HIS INTENTIONS WITH RESPECT TO RTE OF FLT). THE TWR MADE NO MENTION OF THE TFC. WE CALLED THE TWR AND HE (CTLR) APOLOGIZED SAYING THE HELI HAD OVERSHOT HIS DEP GATE AND HE (THE CTLR) HAD NOT SEEN THE CONFLICT IN TIME TO ISSUE AN ADVISORY. AS ALWAYS, ALERTNESS IN THE TERMINAL AREA IS CRUCIAL AND ADHERENCE TO AN ASSIGNED DEP IS A MUST UNLESS CIRCUMSTANCES PROHIBIT DOING SO SAFELY. THIS RPT HAS BEEN READ AND SUBMITTED AS A CREW EFFORT BY THE CAPT AND FO--THUS ONLY 1 COPY IS BEING SUBMITTED.
