HUMAN ERROR MODE EFFECTS AND CRITICALITY ANALYSIS IN AVIATION ENGINE ASSEMBLY PROCESS

摘要

Engine plays an important role in the work of aviation plane. Though much attention has been paid to engine reliability during its design, development and production phases, little study has been carried on about "human error", which is another important factor affecting the quality of the engine and the safety of operators. Any human error or hardware failure may induce a severe consequence. In order to assure the safety of operators and to upgrade the quality and reliability of the engine, referring to failure mode effects and criticality analysis (FMECA) used in engineering reliability, human error mode effects and criticality analysis(HEMECA) method was applied to i-dentify the critical human tasks, critical human error modes, and the human reliability information of engine assembly tasks in this study. This method can also be used for human error analysis in other system.
