Lufthansa A343 and Lufthansa Cityline CRJ9 at Frankfurt, loss of separation on departure and go around on Jul 13th 2019
A Lufthansa Airbus A340-300, flight LH-780 from Frankfurt(Germany) to Nanjing (China), was lined up and waiting for takeoff from Frankfurt’s runway 25C.
A Lufthansa Cityline Canadair CRJ-900, flight LH-1015 from Brussels (Belgium) to Frankfurt(Germany), was on final approach to Frankfurt’s runway 25R.
While LH-1015 was still on final approach tower cleared LH-780 for takeoff, the A340 commenced their takeoff roll. The crew of the CRJ however initiated a go around.
After the crew reported the go around, Tower immediately restricted the climb of the CRJ to 2000 feet and instructed a right hand turn, LH-780 was instructed to turn left.
The crew of LH-780 reported they had a TCAS warning now in a left hand turn at about 2400 feet. After the developing conflict was resolved, the CRJ crew reported they had the A340 always on their TCAS and in sight, there wasn’t any issue, they had to go around, descending through 300 feet they couldn’t hold the aircraft, it was nearly uncontrollable. The CRJ crew reported on downwind that they had received a TCAS resolution advisory for a very short period of time.
The A340 continued to Nanjing for a safe landing, the CRJ positioned for another approach land landed safely on runway 25R about 15 minutes after the go around. ATC explained to other traffic that the LH-780 had turned right, they detected/recognized the go around very late, that’s why it got very tight, otherwise they could have separated them better.
Standard Departures out of runways 25C and 25L provide for right hand turns, in some cases for left hand turns after becoming airborne.
Germany’s BFU rated the occurrence an incident and have not opened an investigation into the occurrence.
