Analysis of Iran’s civil aviation accidents and serious ‎incidents from 1979 to 2021 using failure mode and ‎effects analysis and multi-attribute decision making ‎methods

Since humans have begun to fly and construct various aircraft, the occurred accidents and incidents ‎have always resulted in irreparable injuries and damages. Therefore, today, aviators especially airlines ‎continuously trying to maintain the maximum level of safety and reduce the rate of accidents by ‎spending resources. In this research, by analyzing the available reports and information for 46 accidents ‎and serious incidents in Iran's civil aviation between 1979 and 2021, first, a statistical-analytical ‎evaluation is performed, then influential factors like failures and errors in these occurrences are analyzed ‎by using failure mode and effects analysis and multi-attribute decision making. The statistical population of this research includes a panel of experts and experts in the field of aviation and air accidents, and a questionnaire was used to collect the required information. According to findings, ‎human is the most important factor, Fokker100 is the most engaged aircraft and pilots with low ages and ‎experiences are the most vulnerable factors in mentioned occurrences; in addition, failures in landing ‎system and engines and also the pilot error in not following the structures were the most important ‎factors.‎
