Since aviation is one of the sectors involving high levels of risk in today’s world, the presence of a safe working environment is crucial for both flight operations and aircraft maintenance services. Thus, it is vital for aviation workers to be aware of unsafe situations as well as dangers and potential risks in order to create a safe environment and establish an organizational safety culture. One of the fundamental components of such awareness is information, and voluntary reporting of this information as well as unsafe situations by aviation employees is one of the most important ways for managers to access this information. Reporting in aviation safety is essential in terms of data collection, analysis and sharing information among aviation employees while evaluating accidents, potential risks and dangers. Otherwise, non-reporting behavior might result in unnoticed and unforeseen but preventable accidents. The aim of this study is to investigate the reasons of non-reporting behavior of military aviation line maintenance staff and offer suggestions to encourage voluntary reporting behavior that might contribute to creating an effective flight and ground safety culture. The study uses a hybrid research method to achieve this purpose. The data obtained from the related literature and unstructured interviews conducted with the expert personnel were measured by using a 5-point Likert scale and the reasons with a mean of 3 and above were evaluated together with a team of 7 in a consensus, and later, non-reporting criteria of military aviation line maintenance personnel were ranked in terms of importance by using the AHP (Analytical Hierarchical Process) method. According to the results of the study, the most important factors leading to voluntary silence (non-reporting) behavior of military aviation maintenance personnel are fear of being punished (the criteria weight=0.25), communication problems / previous reporting experiences (the criteria weight for both=0.17), i

Ramp handling acts a vital role in sustainable airport operations. The ramp related services provided to aircraft and their passengers at the airports are related to the landing, take-off, unloading and loading of the aircraft. Human resource is a key component in ramp handling operation and errors by employees cause significant accidents or incidents. The main purpose of the current study is to prioritize critical risk factors in ramp handling operations by using an integrated risk management approach and optimizing human performance while minimizing both failures and errors by employees. In this study, an integrated qualitative and quantitative risk assessment method is carried out by considering the factors that affect the possibility of ramp handling personnel errors. Initially, 113 risk factors are identified by using the academic literature, documents prepared by international organizations, and then by consulting expert opinions. Subsequently, a prioritization by professionals working on the ramp handling operations, based on the principles of the Analytic Hierarchy Process (AHP) method resulted in the final selection of the 41 most important risks. Then, a risk assessment approach is applied by designing a matrix, based on three dimensions; probability, severity (impact) and relation ratio which ultimately resulted in risk index generation and a risk map model is developed. Finally eleven (11) risk factors are identified as they have higher probabilities to occur and possible higher negative consequences. Thanks to the integrated risk assessment applied in this study, it is aimed to ensure that all systems of the organization operate in a safe way and that an efficient safety culture is formed. Allocating a single resource to many risks, instead of facing the risks of the ramp personnel one by one, leads to more efficient use of resources and higher performance of ground handling companies.
