Abstract :
Aircraft maintenance has a very important value to always be maintained,
so that the reliability, feasibility and readiness of the aircraft. Indonesia Air
Transport & Infrastructure (IAT), is one of the charter companies, the aircraft
used iat is EC 155B1 type. The author uses two research methods, the first is
Reliability control program (defect monitoring) which is used to select and
validate component damage data. Weibull calculations are used for processing
the reliability data of selected components.
The results of the analysis defect monitoring during the 2014-2019 are
ATA chapter 34 navigation which has the highest number of defects, but the
components in ATA chapter 34 navigation do not have a component age limit
recorded in the document airworthiness limitation section (ALS) so that it is
replaced by ATA chapter 62 main rotor . The components in the ATA chapter 62
main rotor selected are the scissors lower link component, the pitch change rod-
end, and the frequency of the rod-end adapter.
The results of the Weibull analysis of the components of the scissors lower
link, pitch change rod-eng, and the frequency of the rod-end adapters performed,
obtained reliability value data seen from the indication value ? = 2.0967 (scissors
lower link), ? = 2.5884 (Frequency Adapter Rod-en ), and the value ? = 6.3102
(pitch change rod-end). All three components have a value of ?> 1 which
indicates the same type of damage, namely implies wear-out. All three
components indicate the same type of failure (wear out failure), then the proper
maintenance program for the three components is to do scheduled maintenance.
by doing preventive maintenance such as daily check, post & pre-flight check,
detailed inspection and others, depending on the maintenance program
adjustments that will be made from the results of this analysis.
