  • Flight safety is identically with the performance of aircraft. To have a standard of flight safety, an aircraft needs good maintenance to achieve the best performance. An aircraft technician should have a good qualification as stated in ICAO. They have complex job that usually create high workload which is harmful for the flight safety. The aim of this research is to analize the workload experienced by the aircraft technician at Lion Mentari Airline and in which interval, to examine factors affecting the workload value and to examine the influence of workload value on flight safety. The aircraft technician workload was analyzed using Subjective Workload Assessment Technique (SWAT) software. The data was taken from 50 aircraft technicians of Lion Mentari Airline in line maintenance. They asked to rank the Sort Card according to their own perception about mental workload. There are combination levels that should be made in order from the lowest to the highest. The mental workload combination consists of Time Load (T), Mental Effort Load (E) amd Psychological Stress Load (S). The result shows that the workload experienced by the aircraft technician at Lion Mentari Airline is 61.44 which are in the interval of Over Load. From three dimensional workload, Time Load (T) has the highest value (percentage) than Mental Effor Load (E) and Psychological Stress Load (S) which is 40.67% (participant 1-25) and 41.48% (participant 26-50). It shows that the workload concern of Aircraft technician at Lion Mentari Airline in line maintenance is on Time Load. The high workload will make high error risks and the probability to produce accidents is high. The errors can be reduced or prevented by identified causes which is most frequently occur (Dirty Dozen) and make barrier (Safety Nets/ Safeguard) to prevent the accident to be happened using Swiss Cheese Model and ICAOâ��s SHELL Model Approach.
