The aircraft experienced a loud bang followed by Engine No.1 uncommanded shut down during climb out at approximately 14000 ft. The aircraft made a safe single engine landing at Skardu Airport. The most probable cause could be the accumulation of environmental contaminants through serviced 011 or formation of burnt oil residues m the Jets due to inadequate cooling prior to engine shut downs during service life of the engine. This led to the failure of bearing No. 2 of the engine after oil starvation due to blockage of its oil delivery jets.
