Executive Summary:During the flight from London Heathrow to Geneva after the climb to FL290 and establishing cruise conditions at 11:05 UTC a loud bang was heard by the flight and cabin crew. The cabin crew advised the cockpit crew by interphone of their observations. After checking all parameters, all seemed normal and the flight continued to Geneva.

During descent in to Geneva for a landing on runway 05, around 11:46 UTC the vibrations on the RH engine increased and fluctuated as well as the EGT of the RH engine.

A loss of engine power was felt, so that a corrective rudder input had to be given.

During the landing and flare phase, fire was observed by a crew in the proximity of the runway and TWR was advised. After landing, the warning light “ENG #2 OIL FILTER CLOGGED” came on. The crew shut down the RH engine.

Geneva Apron advised the crew that one engine is on fire and asks them if they can stop were they are, which means on the taxiway. The crew complied with the request.

The aircraft stopped on the taxiway. Both fire extinguisher bottles of the RH engine were discharged. The fire brigade arrived and cooled the RH engine. The fire has ceased, as no more fuel was injected due to the shut off of the engine.

After the extinguishing of the fire and the cooling down of the engines, the CDR decided to let the passengers disembark via the stairways on the taxiway.

Nobody was hurt during the disembarkation of the plane and the passengers remained calm.

The incident was caused by the failure of bearing No. 4 of the engine #2 with resulting damage to the HPT blade tips.
