HFACS for Mapping Strengthening Human Factor Training Material on Prospective Aircraft Technicians

Abstract

In order to reduce the number of flight accidents due to human factors, the ICAO issued Standards and Recommended Practices which were followed up by the Indonesian government by issuing regulations regarding the need to attend human factor training for technician personnel. One method that can be used to analyse flight accidents related to human factors is the Human Factors Analysis and Classification System (HFACS). HFACS analysis will be able to provide information about the weak points of the human factor, where this information will provide improvement in the material implementation of human factor training. This research is a descriptive study, where data obtained from online questionnaires will be analysed based on the HFACS. The population is aircraft maintenance technicians graduated from Surabaya aviation polytechnic for 410 people distributed in various MRO companies with samples taken for 186 people according to Herry King Nomogram, with a confidence level of 95%. The results of the analysis using the HFACS of the highest percentage are unsafe act operators, precondition for unsafe, unsafe supervision, organizational influence which is necessary to strengthen and enrich the syllabus of human factors on topic of human error, performance management, communication skill, situation awareness and reporting and investigating errors.
