Abstract :
The use of helicopters is very useful for Indonesia's natural conditions
which is in the form of islands. In order to support the helicopter's capabilities, an
AFCS actuator or automatic flight control system actuator is needed to make the
flight automatically. Therefore, the author tries to conduct a reliability analysis to
determine the level of reliability of the AFCS Actuator component in S-76
helicopter.
The method used to conduct the analysis is the Weibull distribution
method, which is one of several methods that are often used. The main objective is
to determine the level of reliability and characteristics of the failure modes that
often occur in these components. By analyzing at the results of calculations and
types of failures, it can be seen the types of effective treatments to be applied to
the AFCS Actuator component.
From calculations, it is known that AFCS actuator had increased failure
at the beginning of their use. Based on the ? score obtained, it is 0.8099 which
means that the ? < 1 is categorized as preliminary failure. The b score on the
AFCS actuator component is 1.235 in which the probability of failure is 1.2 %,
indicates that the component is experiencing bagin failure. Effective treatment
policies for applying those AFCS actuators are component modifications.
