A Manutenção Aeronáutica é constantemente alvo de estudos e alterações para atingir um variado espetro de fins tais como, a redução dos seus custos, o melhoramento da segurança operacional e a aeronavegabilidade. A Fiabilidade anda de mãos dadas com a Manutenção Aeronáutica nestas tarefas. O presente estudo procurou ir ao encontro das necessidadades da entidade com a qual foi desenvolvido, a SATA Air Açores, de forma a dar uma nova visão acerca da fiabilidade de sistemas e uma nova forma de avaliar a fiabilidade de uma frota de aeronaves.
O trabalho prático desenvolvido assenta, numa primeira parte, em estudar a fiabilidade intrínseca do subsistema de Extensão do Trem, tendo como base os principais componentes nos sistemas Hidráulico e Trem de Aterragem. Numa segunda parte, avalia-se a fiabilidade de uma frota de 4 aeronaves do tipo Bombardier Dash 8 Q-400 tendo em conta os 10 componentes menos fiáveis, aplicando um método ainda não utilizado pela operadora e definindo níveis de alerta para cada componente.
No desenvolvimento deste trabalho utilizaram-se dados disponibilizados pela Bombardier Aerospace e pela SATA Air Açores, no entanto, este estudo permite a utilização destes métodos para qualquer frota de aeronaves.
Aircraft Maintenance is in constant research and change in order to reach a wide spectrum of purposes such as cost reduction, improvement of operational safety and airworthiness. The reliability goes hand in hand with Aircraft Maintenance in what pertains to these tasks. This study sought to meet the necessities of the entity in which it was developed, SATA Air Azores, seeking to give a new vision on system reliability and a new way of assessing the reliability of a fleet of aircraft. The practical work lays, in a first instance, upon the study of the intrinsic reliability of the subsystem extension of the landing gear, based on the main components of the hydraulic and landing gear systems. The second part evaluates the reliability of a fleet of 4 aircraft of the type Bombardier Dash 8 Q-400 taking into account the 10 least reliable components, using a method not yet used by the operator, setting alert levels for each component. In the development of this work data was provided by Bombardier Aerospace and SATA Air Azores was used, however, this study allows the use of these methods for any fleet of aircraft.
