The force that generated from the engine is a thrust, the thrust is used to propel the aircraft. The thrust force is produced by an engine. In order to maintain the engines that is always in a proper condition, the engine must be well maintenance. Engine maintenance is for analyzing the condition of the aircraft engine to ensure thats the engine is always in good condition. This research aims to determine the results of the analysis of the CFM56- 7B engine's performance under real conditions. The performance calculation of the CFM56-7B engine is based on data obtained from Test Cell Results and is carried out using formulas found in the Engine Manual Shop 003. After conducting the analysis, the results of the CFM56-7B engine performance calculation show a thrust rating of 26,814 pounds. Meanwhile, the Specific Fuel Consumption (SFC) value obtained for the thrust rating is 0.3915 pounds per hour, with an SFC margin of -6.0%.} }
