A Hop! Embraer ERJ-170 on behalf of Air France, registration F-HBXG performing flight AF-1671 from Lyon to Caen (France), was enroute at FL280 about 70nm southeast of Paris when the aircraft was overflown by a Cessna 550 business jet, that had been cleared to climb to FL270. Both aircraft were able to continue to their destinations without further incidents.

The BEA reported the Cessna 550, performing a flight from Paris Le Bourget (France) to Geneva (Switzerland) encountered problems with their autopilot while climbing through FL230, the pitch angle increased and the aircraft suffered a load factor. The aircraft had been cleared to climb to FL270, but overflew the Embraer ERJ170 that was enroute at FL280. The Cessna crew reported they had a malfunction of the #1 altitude and speed indication system, the transponder therefore reported erroneously they were on FL270. This created a loss of separation with the potential of a collision without triggering TCAS. The BEA rated the occurrence an incident (?) only and opened an investigation.
