A Cargolux Boeing 747-400 freighter, registration LX-LCL performing flight
CV-7986 from Novosibirsk (Russia) to Shanghai Pudong (China), was cleared to climb to FL310 out of Novosibirsk but climbed beyond FL310. When the aircraft climbed through FL312 TCAS activated with a resolution advisory due to conflicting traffic in opposite direction.
A SF ShunFeng Airlines Boeing 747-400 freighter, registration B-2423 performing flight O3-7201 from Wuhan (China) to Frankfurt/Main (Germany), was enroute at FL320 in opposite direction about 4.5nm from the Cargolux aircraft, when the crew also received a TCAS resolution advisory.
The Cargolux descended back to FL310 which resolved the TCAS resolution. Both aircraft continued to their destinations without further incident.
Rosaviatsia reported Cargolux did not report their TCAS resolution advisory.
