Air Traffic Incident | Operational Error |
Narrative:
Aircraft had just departed tmb en route for msy. Our clearance was to climb to 2000 ft MSL on runway heading. After leveling off at 2000 ft MSL, controller assigned a new heading of 290 degrees. A min or 2 had gone by when the controller issued us an immediate right turn to 020 degrees. As we were in the turn, our TCASII alert sounded and a 300 series cessna could be seen approximately 1200 ft off our left side executing a tight right turn. A few more mins later, still at 2000 ft MSL and on our heading of 020 degrees, we received another TCASII alert for traffic less than 1 mi at our same altitude and 12 O'clock position. We initiated an immediate climb just as the controller issued us an immediate climb to 6000 ft MSL. We feel the problem arose due to a heavy traffic area, lack of controller supervision and excessive workload. Our actions were for the safety of the flight. The miami control facility has been notified and has explained that this incident was an operational control error. Callback conversation with reporter revealed the following information: reporter said they had departed to west into IMC and conflicted with a twin cessna observed on TCASII 1200 ft away indicating the same altitude. A short time later they conflicted with an air carrier about as close. He said the controller was very busy and may have missed issuing a climb clearance. He said his company was told by the mia control facility that the conflict was classified as operational control error.

Title: C750 CREW DEPART TMB TO THE W IN IMC AND CONFLICT WITH A TWIN CESSNA A SHORT TIME LATER WITH AN ACR.
Narrative: ACFT HAD JUST DEPARTED TMB ENRTE FOR MSY. OUR CLRNC WAS TO CLB TO 2000 FT MSL ON RWY HDG. AFTER LEVELING OFF AT 2000 FT MSL, CTLR ASSIGNED A NEW HDG OF 290 DEGS. A MIN OR 2 HAD GONE BY WHEN THE CTLR ISSUED US AN IMMEDIATE R TURN TO 020 DEGS. AS WE WERE IN THE TURN, OUR TCASII ALERT SOUNDED AND A 300 SERIES CESSNA COULD BE SEEN APPROX 1200 FT OFF OUR L SIDE EXECUTING A TIGHT R TURN. A FEW MORE MINS LATER, STILL AT 2000 FT MSL AND ON OUR HDG OF 020 DEGS, WE RECEIVED ANOTHER TCASII ALERT FOR TFC LESS THAN 1 MI AT OUR SAME ALT AND 12 O'CLOCK POS. WE INITIATED AN IMMEDIATE CLB JUST AS THE CTLR ISSUED US AN IMMEDIATE CLB TO 6000 FT MSL. WE FEEL THE PROB AROSE DUE TO A HVY TFC AREA, LACK OF CTLR SUPERVISION AND EXCESSIVE WORKLOAD. OUR ACTIONS WERE FOR THE SAFETY OF THE FLT. THE MIAMI CTL FACILITY HAS BEEN NOTIFIED AND HAS EXPLAINED THAT THIS INCIDENT WAS AN OPERATIONAL CTL ERROR. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR SAID THEY HAD DEPARTED TO W INTO IMC AND CONFLICTED WITH A TWIN CESSNA OBSERVED ON TCASII 1200 FT AWAY INDICATING THE SAME ALT. A SHORT TIME LATER THEY CONFLICTED WITH AN ACR ABOUT AS CLOSE. HE SAID THE CTLR WAS VERY BUSY AND MAY HAVE MISSED ISSUING A CLB CLRNC. HE SAID HIS COMPANY WAS TOLD BY THE MIA CTL FACILITY THAT THE CONFLICT WAS CLASSIFIED AS OPERATIONAL CTL ERROR.
