Aviation industry ensure and prioritize the safety of an aircraft. But somehow air crash occurs due to mainly three factors which are technical factor, external factor and human factor. Out of these, human factor or latent error is most crucial cause of accidents because it is almost unnoticeable and often overlooked while finding the cause of accidents. For this issue, HFACS model was proposed which looks into different types of latent errors that may occur in aviation industry. Using this model, accidents occurred in Pakistani, American and Canadian Airlines were analysed and found out what kind of latent error is occurred most and which country’s airline reported more accidents due to latent error. It was found that Canadian Airlines reported more case due to latent error and was found that the latent error is not blamed as the major cause of the accident.enThesis
