Abstract

The lycoming engine piper pa28-161 controlled by fadec (full authority digital engine control) has four cylinders, in-line dohc (double over head camshaf) with the work of intakes, comprrezion; Exhaust, power, and exhaust. The damage that results in the plane's down of RPM (revolution per minute) carburetor, carburetor heat switch, carburetor air filter, magneto, Igniter plug, resulting in both incident and occurrence so as to cause casualties, it is best to decelerate the revolution per minute and establish the cause of the decline. This study tested several components including Carburetor, Carburetor Heat Switch, Carburetor Air Filter, Magneto, Igniter Plug and analyzed using the Failure Mode Effects and Criticality Analysis (FMECA) method which means the method with two analyses which is the analysis of Failure mode and effect analisys (FMEA) and criticality analysis (CA), this FMEA is done by means of identifying potential failure, for CA to be done by calculating the results of the FMEA testing. The result of an analysis was the result of a fmea test of the highest value and the often associated component of carburetor heat switch with RPN value 320, and the lowest ca test results were carburetor air filter with 48,9216 in the rankings and the highest ca value being carburetor with an 255,5904. These components should be prioritized in treatment because they are at very high risk.
