A CSA Czech Airlines Airbus A319-100, registration OK-MEL performing flight OK-803 from Bucharest Otopeni (Romania) to Prague (Czech Republic), was climbing out of Bucharest when the crew noticed vibrations from the floor at the cockpit and the forward galley associated with low frequency noise that appeared to originate from the air conditioning system. The crew continued the flight as planned. During the descent into Prague the vibrations and sound suddenly ceased, however an odour of burning wires and light haze appeared in the cockpit. A short time later a “VENT BLOWER FAULT” was displayed on the ECAM. The crew carried out the ECAM actions, the odour and haze disappeared. The aircraft continued for a safe landing in Prague and taxied to the gate, where passengers disembarked normally.

In their fourth quarter 2018 bulletin Czechia’s UZPLN reported the air conditioning “BLOWER FAN” was replaced.
