Abstract
En la industria aeronáutica detrás de la seguridad y comodidad que ofrecen los aviones, miles de horas de trabajo y entrenamiento de muchos ingenieros, técnicos y mecánicos, además de un gran costo económico son asumidos por las compañías para realizar un correcto mantenimiento. Estos tienen distintos procesos de verificación, determinados por una estricta planificación, abarcando dos tipos: el programado y no programado. En relación al programado este se realiza siguiendo un programa ya establecido según diferentes variables como pueden ser los tiempos de trabajos, kilómetros recorridos entre otros. En tanto el no programado surge como una falla no contemplada a la hora de realizar el otro tipo de mantenimiento, en que muchas veces estos afectan de la misma o de peor forma, generando impacto en temas de tiempo, además de costos en repuestos y mano de obras al tener que reparar fallas que no estaban contempladas en la mantención original. Es en este último tipo de mantenimiento el cual se centrará este trabajo, buscando encontrar una metodología que ayude a localizar y entender el comportamiento de 27;878 fallas obtenidas estos últimos tres años, en base a técnicas estadísticas para ser clasificadas y luego ser tratadas con métodos de análisis de fallas, como por ejemplo FMECA, análisis de modos, efectos y criticidad. La metodología busca abordar un orden lógico y crítico que pueda finalmente entregar, junto a un experto, recomendaciones en el tratamiento de ellas. La metodología apunta a que la empresa pueda prevenir y conocer estas fallas que no están presentes en un plan de mantenimiento programado, busca que estas sean tratadas e incluidas en él, en base al seguimiento de las fallas presentes en ATAS y patrones comunes entre las diferentes patentes de la flota.
In the aviation industry behind the safety and comfort offered by aircraft, thousands of hours of work and training of many engineers, technicians and mechanics, plus a large economic costs are borne by companies to perform proper maintenance. These have different verification processes, determined by strict planning, covering two types: scheduled and unscheduled. Scheduled maintenance is performed following a program already established by different variables such as work times, kilometers traveled among others. As for the unscheduled emerges as a fault not covered when performing other maintenance, that often they affect the same or worse shape, making an impact on issues of time, plus costs in parts and workforce by having to repair faults that were not covered by the original maintenance. It is in this last type of maintenance which will focus this work, seeking to find a methodology to help locate and understand the behavior of 27;878 failures obtained the last three years, based on statistical techniques to be classified and then be treated with methods failure analysis, such as FMECA, analysis modes, effects and criticality. The methodology seeks to address a logical and critical order that can finally deliver, together with an expert recommendations for treating them. The methodology suggests that the company can prevent and knowing these faults are not present in a scheduled maintenance plan, intended that these be treated and included in it, based on monitoring of faults present in ATAS and common patterns between different patents of aircraft fleet.
