Safety is a major factor in air transportation. Aircraft maintenance serves to ensure airworthiness of aircraft operation. When aircraft maintenance is not carried out in accordance with applicable standards and procedures, then it will endanger the safety of the flight. Aircraft maintenance is an important unit in ensuring fleet availability. From this study it is known that the connection between accidents and maintenance shows the importance of an analysis to identify factors that might affect the aircraft maintenance unit. Research in the aviation safety is closely related to the safety climate that is considered a leading indicator of safety performance and safety outcomes. This research develops a safety climate model by adding organizational design factors in consisting variables of structure and environment variables to explain the relationship between organizational structure and environment variables to the safety climate and safety climate to safety performance factors consisting variables of safety knowledge, unsafe behavior and reporting behavior, as well as the Safety climate to safety outcomes consisting variables of Safety Risk and Airworthines. The eight variables are Structure, Environment, Safety Climate, Safety Knowledge, Unsafe Actions, and Reporting Behavior, Safety Risks, These are tested with 13 hypotheses. This study included a sample of 306 technicians who participated in a crosssectional purposive survey. Respondents work for aircraft maintenance companies that have the capability of Maintenance Repair Overhaul (MRO), which is 5 companies. The collected data were analyzed by Structural Equation Modeling (SEM). The scale used uses a Likert scale with a range of 1 to 5 to measure the perception of safety owned by the respondents. Response of respondents to the average instrument were of good value, and the reliability and valididity test for instrument are reliable instruments. After the normality test, validity test with 2NDCFA and Variance Extracted and Construct Reliability were only 97 indicator items that were feasible to be processed. The model is declared good by using the Goodness of fit Index and is worthy of analysis. All hypotheses have been confirmed. From the safety climate model that is developed, the organizational structure and environment has 8.58% of the total influence on the safety climate and the remaining 91.42% must be explained by other causative factors from outside this model. The total influence of climate on Airworthiness is 6.71%, unsafe act have a total effect of 20.78% on Airworthiness, reporting gives a total effect of 8.23% on Airworthiness. Influence of Climate, unsafe act, reporting to Airworthiness is 35.64% and the remaining 64.36% must be explained by other factors from outside this regression model. In general this study provide important contributions to research models and especially aircraft maintenance organizations. Using this information can help investigate the reasons why a safety climate have affect to safety performance and safety outcomes. Futhermore, management can improve the organization's safety climate in order to improve Safety Performance and Airworthiness. Recommendations can be submitted such as consistency are needed in the application of international standards and aviation regulations and supervision in the efforts to foster aviation safety by regulators and operators. It is necessary to increase human resources because it determines the progress of the organization in dealing with various changes, such as the creation of a competitive national aviation industry. Future research can investigate other variables, specifically conditions before unsafe act happen so that worker characteristics will complement research in aircraft maintenance organizations. This study provides direction in the form of Safety Risk reduction and increased Airworthiness.
