Abstract :
The AFCS actuator on a helicopter is a system that helps pilots when taking
off, sailing, landing. Similar to the automatic pilot system on fixed wing aircraft, the
AFCS Actuator is an automatic system used from airplanes to do a landing. In addition,
with the AFCS it will facilitating pilots, it will provide comfort for passengers. Based on
the information obtained from the mechanics as well as the engineering section, at
logbook maintenance in the Sikorsky S76C ++ Helicopter, which is related to the AFCS
Actuator. Where the problem concerns the driver of the AFCS or its Actuator cannot
work properly.
Based on the data that has been obtained in the form of flight maintenance
log, component change will be processed using Weibull DR 21 software that will
produce output parameters that will be used as analysis material.
Calculation results using Weibull DR 21 software show that the reliability
value of the AFCS Actuator decreases with age. The MTTF value obtained is MTTF
187.87 Hours or the system can work well until it fails after increasing the age of
187.87 Hours. The failure rate experienced by the AFCS Actuator is decreasing with
age. Preventive maintenance activities are very effective against the type of degradation
experienced by the AFCS Actuator
