飛機發動機維修廠訓練檢定系統之改善 -以A公司為例

Abstract

飛航安全為航空產業一重要因子，而飛機發動機修護品質更直接影響飛航安全，所以各國民航局對民用飛機發動機維修廠之成立皆有相關要求，在符合法規要求下維修廠依照發動機製造原廠技術手冊對發動機進行維修，維修廠維修人員的訓練與檢定又與維修品質息息相關，確保維修人員技能維持一定的水準除了可以減低人為缺失事件發生機率與維修重工的成本浪費，也可以增加工作的效率。維修廠依規定須有人員初始訓練檢定系以確認維修人員的技能符合要求，但對於初始檢定後的定期檢定因沒有相關法規之規定而容易被忽視。 本研究以民用飛機發動機維修廠為研究實例，該廠維修人員之訓練檢定系統僅有技能初始檢定之要求，長期下來多重技能之維修人員部分技能退化而無法得知，直接造成工作效率下降影響交運時間，維修品質不符合要求需要重工使品質不良成本居高不下，本研究針對飛機發動機維修廠A廠建置維修人員定期檢定計畫，以三位考官針對工作標準、工作知識、實作熟練度與完工品質等四項標準以職能盤點的方式實際對全廠維修人員進行檢定，除可確實掌握維修人員的技能現況，透過此方法亦可確認技能退化之人員對其加強訓練，確保維修人員技能水準進而降低因人為誤失所產生的維修不良成本。

Flight safety is a key factor in the aviation industry, and the aircraft engine repair is direct impact to flight safety. There is establishment requirement for engine repair station for each civil aviation agency. To compliance with civil aviation regulatory requirements the repair station should follow the engine manufacturer technical data for engine repair. The training and qualification system for repair staffs of repair station is directly related to the maintenance quality. Keeping repair staff skills to a certain level will help to decrease the human error occurred, reduce the rework cost and increase repair efficiency. According to the civil aviation regulatory requirements, repair station should have a training and qualification system to ensure the competency of repair staffs. However, there is only initial training/qualification requirement and lack of periodic training/qualification criteria.

This research takes an aircraft engine component repair station A as a real case to study. The repair station A only has the initial training/qualification requirements for repair staffs and can’t detect the skills degradation for multi-skills repair staff parts. This caused a direct result of reduced work efficiency affect the delivery time, rework for poor repair quality and high cost of poor quality rework. In this research we recommend and help repair station A to build a periodic re-qualification system for repair staffs. Three examiners carried out the competency test for all repair staffs in 4 categories: practical performance, manual understanding, standard work and outcome quality. The re-qualification system helps to find the current skills competency status and discover skill degradation staffs and provide remedial training to them. It is workable to ensure repair staffs skill competency, decrease human error occurrence and reduce the cost of rework of poor quality
