An Austrian Airlines Airbus A320-200, registration OE-LBI performing flight OS-208 from Frankfurt/Main (Germany) to Vienna (Austria), was climbing out of Frankfurt’s runway 18 when the crew stopped the climb at FL090 reporting smoke on board. The aircraft returned to Frankfurt for a safe landing on runway 25C about 15 minutes after departure.

Several passengers reported there had been smoke on board of the aircraft, the crew also talked about smoke (and not an odour/smell).

The airline reported the aircraft returned due to an unusual smell on board. There had been problems with the APU.

The aircraft remained on the ground in Frankfurt for about 18 hours before returning to service.
