The Airbus A320-200, registration EC-JFN, operated flight IB3214, with destination Brussels (Belgium).
During the climb after takeoff from Madrid Airport, when reaching 3500 feet, the flight crew perceived an intense smell of burning, confirming the appearance of smoke in the cockpit, coming from the air conditioning vents. The crew put on their oxygen masks, declaring an emergency and requesting a return to the airport of origin.
From the passenger cabin, the presence of smoke was also reported and the aircraft commander instructed the use of the emergency masks.
Once the return to Madrid was authorized, the landing was made without any other incidents, and the smoke was almost completely dissipated from the aircraft.
The investigation has determined the incident was most likely caused by an inadequate maintenance practice, which led to the contamination of the bleed air from engine 1 and caused smoke to enter the cabins through the air conditioning vents.
The air was most probably contaminated by the residues of grease, oil and bird remains, which were burned during the routine operation of the engine, having not been removed during the maintenance carried out after the bird ingestion during the preceding flight. Oil spills left by prior maintenance procedures could also be a factor.
