Narrative:

On 9/wed/90 at PM05, we were cleared for takeoff. No traffic advisories were issued and we were cleared for a right turn on course after departure. After turning west at 600' AGL, we leveled at 2500' MSL heading west. Another aircraft called and asked tower if he had worked an small aircraft a couple of mins ago. He then said that he had a near miss with an small aircraft heading west. It had to be us because we were the only small aircraft departing at the time. However, we never saw the conflicting traffic, and the tower never called traffic. This situation demonstrates that collision avoidance responsibility ultimately rests with the pilot, and that vigilance, even in a controled situation, is vital.

Original NASA ASRS Text

Title: NMAC.

Narrative: ON 9/WED/90 AT PM05, WE WERE CLRED FOR TKOF. NO TFC ADVISORIES WERE ISSUED AND WE WERE CLRED FOR A RIGHT TURN ON COURSE AFTER DEP. AFTER TURNING W AT 600' AGL, WE LEVELED AT 2500' MSL HDG W. ANOTHER ACFT CALLED AND ASKED TWR IF HE HAD WORKED AN SMA A COUPLE OF MINS AGO. HE THEN SAID THAT HE HAD A NEAR MISS WITH AN SMA HDG W. IT HAD TO BE US BECAUSE WE WERE THE ONLY SMA DEPARTING AT THE TIME. HOWEVER, WE NEVER SAW THE CONFLICTING TFC, AND THE TWR NEVER CALLED TFC. THIS SITUATION DEMONSTRATES THAT COLLISION AVOIDANCE RESPONSIBILITY ULTIMATELY RESTS WITH THE PLT, AND THAT VIGILANCE, EVEN IN A CTLED SITUATION, IS VITAL.
