Regulations of Airworthiness and Maintenance Management for Aviation Products, Appliances and Parts Article 2
Definitions:1.Maintenance means inspection, overhaul, repair, preservation, and the replacement of part in order to maintain the airworthiness of an aircraft, but excludes preventive maintenance.2.Preventive maintenance means simple or minor inspection, assembly, preservation operations and the replacement of small standard part not involving complex assembly operations.3.Repair means the restoration of an aircraft, its powerplant, propeller, components and part to an airworthy condition as defined by the appropriate airworthiness standards and requirements. It is classified as following:(1) Major repair means a repair that if improperly done, might appreciably affect weight, balance, structural strength, performance, powerplant operation, flight characteristics, or other qualities affecting airworthiness; or that is not done according to accepted practices or cannot be done by elementary operations.(1) Major alteration means an alteration not listed in the aircraft, aircraft engine, or propeller specifications that might appreciably affect weight, balance, structural strength, performance, powerplant operation, flight characteristics, or other qualities affecting airworthiness; or that(2) Minor repair means a repair other than a major repair.4.Alteration means a modification work which is not listed in the original design standard to add or subtract component and part, or change its original performance or function to an aircraft, its powerplant, or propeller. It is classified as following:(1) Major alteration means an alteration not listed in the aircraft, aircraft engine, or propeller specifications that might appreciably affect weight, balance, structural strength, performance, powerplant operation, flight characteristics, or other qualities affecting airworthiness; or that is not done according to accepted practices or cannot be done by elementary operations.(2) Minor alteration means an alteration other than a major alteration.5.Rebuilding means to restore the aircraft, its powerplant, propeller, component or part to the applicable airworthiness standards by disassembly, cleaning, inspection, repair, reassembly, and test to the same tolerances and limits as a new item in accordance with methods, techniques, and practices acceptable to the CAA.6.Operating limitation means the necessary limitations with concerning weight, balance, structural strength, performance, powerplant operation, flight characteristics, and quality of maneuver and equipment operation to comply with applicable airworthiness standards and maintain continued airworthiness during flight.7.Aircraft powerplant means aircraft engine, its attachments and accessories. Aircraft engine means an engine that is used for propelling aircraft. It includes superchargers and turbines.8.Instructions for Continued Airworthiness means the necessary airworthiness information which describe methods, techniques, and practices to perform maintenance, preventive maintenance or rebuilding to an aircraft, its powerplant, propeller, component or part.9.Life-limited part means any part for which a mandatory replacement limit is specified in the type design, the Instructions for Continued Airworthiness, or the maintenance manual.10.Life status means the accumulated cycles, hours, or any other mandatory replacement limit of a life-limited part.11.Airframe means the fuselage, booms, nacelles, cowlings, fairings, airfoil surfaces (including rotors but excluding propellers and rotating airfoils of engines), and landing gear of an aircraft and their accessories and controls.
中文原文 航空產品與其各項裝備及零組件適航維修管理規則第2條
本規則用詞，定義如下：
一、維修：指為維持航空器之適航性所從事之翻修、檢查、修理、改裝及更換零件，不包括預防性維修。
二、預防性維修：指簡單之檢查、組裝作業、更換小標準零件及從事封存作業。
三、修理：指將航空器與其發動機、螺旋槳、各項裝備及零組件依適用之適航標準及要求，回復至適航狀況。
包括下列兩種：
（一）大修理：指修理後可能影響航空器之重量、平衡、結構強度、性能、發動機操作、飛行特性、適航品質或修理時不能以一般工作方法施工之航空器與其發動機、螺旋槳、各項裝備及零組件之修理。
（二）小修理：指大修理以外之修理。
四、改裝：指增減航空器與其發動機、螺旋槳、各項裝備或改變其既有之性能、功用所從事之技術修改工作。
包括下列兩種：
（一）大改裝：指改裝後明顯影響航空器之重量、平衡、結構強度、性能、發動機操作、飛行特性、適航品質或改裝時不能以一般工作方法施工，且未明列於現行航空產品與其各項裝備規格之改裝。
（二）小改裝：指大改裝以外之改裝。
五、重造：依民航局同意之方法、技術或實作，及合格之零件，從事拆解、清潔、檢查、修理及組裝，並以等同於新產品之容差及限制進行測試，使航空器與其發動機、螺旋槳、各項裝備及零組件回復至適用之適航標準。
六、操作限制：指航空器操作時為符合適航標準及持續適航所需之重量、平衡、性能、飛行特性、操控品質及裝備操作等限制。
七、航空器發動機（以下簡稱發動機）：指航空器引擎與其附屬裝置及所屬附件。
航空器引擎係用於達成推進航空器之增壓機及渦輪機。
八、持續適航文件：指為維持適航所需之必要資訊，用以說明航空器與其發動機、螺旋槳、各項裝備及零組件之維修、預防性維修或重造之方法、技術及實作。
九、年限管制件：指於型別設計、持續適航文件或維護手冊中規範依年限狀態強制更換之零件。
