The alternator also functions as the main source of electricity to generate the electrical power needed by the aircraft system during flight. Therefore, maintenance of the alternator must be very concerned so that it is always in airworthy condition. Based on information data from the mechanic and by looking at the data on the maintenance record of the Piper PA 28-181 Archer III aircraft at the Indonesian Aviation College. The data analysis data on the maintenance record of the Piper PA 28-181 Archer III Aircraft with data processing using Weibull DR-21 Software and also FMECA (Failure Modes Effects & Criticality Analysis). The results of the analysis using the Weibull DR-21 Software and also FMECA (Failure Modes Effects & Criticality Analysis)shows that the level of reliability of each component has decreased with the Critical Life Time of the alternator component being 2123,078 Hours.} }
