本研究的主要目的是，研究與找出一個能夠適用多機型、節省維修、裝備與人員成本，增加便利性、增加維修效率的方式的可行性研究。當在執行飛機修護工作時，維修手冊中對於維修所需使用的裝備需求，沒有詳細或明確的敘述或註明所使用的工具，或在外站沒有足夠的維修能量需要做緊急修護時，研究提供一個可以彈性使用的維修夾具，更能透過適當的調整適用於不同的機型，節省設備成本。因本身維修的工作經驗與職掌，將研究的目標訂立在中小型窄體客機起落架通用型維修夾具研究。本研究的目的並非研發製造維修設備，只是研究一個可以提供本廠需求的解決方案，所有程序必須符合相關的維修規定，期望將來能提供實際從事起落架維修作業的維修人員參考使用。

The main purpose of this investigation is to research and find feasible ways that can be applied on multiple models of aircrafts, Furthermore to save maintenance costs,equipment costs, manpower, and to improve convenience of use efficiency of maintenance .When executing aircraft maintenance, the maintenance manual does not describe detail and clear instructions, do not indicate specific tools that need to be used or outstation do not have enough repair capability(rating) to execute emergency maintenance(aircraft on ground,AOG).To provide a maintenance fixture that can be used more flexibly. It can be applied to different models of aircrafts through proper adjustment, saving the equipment costs. Due to my experience and responsibility in aircraft maintenance , the target of the investigation were set on common aircraft maintenance fixtures for the landing gear of small and narrow body aircraft. Oppositely the purpose of this study is not to develop or, manufacture and maintenance equipment. It is only to provide research and development for the requirement of the maintenance and solution in company. It is expected that the maintenance staff who in charge the maintenance of the landing gear will gain benefit as a reference in the future.
