前言 • 持续适航维修方案的“ 3个必须”的解释： – 保持飞机适航： – To be airworthy（适航标准）: • (1) The aircraft must conform to its Type Certificate (TC). Conformity to type design is considered attained when the aircraft configuration and the components installed are consistent with the drawings, specifications, and other data that are part of the TC and would include any Supplemental Type Certificate (STC) and field approved alterations incorporated into the aircraft. （符合TC/STC及改装要求） • (2) The aircraft must be in a condition for safe operation. The condition of the aircraft relative to wear and deterioration (e. g. , skin corrosion, window delamination/crazing, fluid leaks, tire wear, etc. ) must be acceptable（缺陷或损伤在手册 标准之内）

前言 • FAA对CAMP包含的内容及范围进行了定义： – CAMP包含的要素（CAMP组成）： • • • 适航责任 • Airworthiness responsibility, 运营人维修手册 • Air carrier maintenance manual, 运营人维修组织机构 • Air carrier maintenance organization, 维修改装的实施与批准 • Accomplishment and approval of maintenance and alterations, 维修计划 • Maintenance schedule, 必检项目 • Required Inspection Items (RII), 维修记录系统 • Maintenance recordkeeping system, 合同维修 • Contract maintenance, 人员培训 • Personnel training, and 持续分析与监控系统 • CASS – 以上10个要素相互关联，共同组成持续适航维修方案（CAMP）， 实现CAMP最高安全目标

CASS • Continuing Analysis & Surveillance System (CASS): a continuous, safety-based, closed-loop cycle of: – – – – surveillance, investigation, data collection, analysis, corrective action, monitoring, and feedback. • CASS requirements are partially satisfied by: – Audit Program; – Reliability Program.

RCA • Airline’s Reliability Program is based on FAA AC 120 -17 A, “Maintenance Control by Reliability Methods”. • Airline’s Reliability Program recognizes that: – Reliability is influenced by environment & operation. – Deficiencies may develop that are peculiar to different types of operations & environments

RCA • Reliability Program cannot yield reliability greater than inherent reliability. – Inappropriate or inadequate maintenance can degrade reliability. – Proper & continuous analysis results in continuously optimized maintenance program. • Effective Reliability Program assures that Airplane Maintenance Program reflects environment & operation

维修计划 • 维修计划可能包含的内容举例（WHAT)： – – – • ADs, • Service Bulletins (SB)/Service Letters, • Replacement of life-limited items, • Replacement of components for periodic overhaul or repair, • Special inspections, • Checks or tests, • Lubrication and servicing, • Tasks identified in the Maintenance Review Board Report (MRBR), • ALs, • CMRs, • Supplemental Structural Inspection Documents (SSID), and • Electrical wiring interconnection system (EWIS).

Engine Maintenance Program • Cover the maintenance of installed engines and off-wing engine(APU): – Usually, the installed engine or APU requirements will be contained in the maintenance schedule. – The off-wing program described in your maintenance manual should provide shop scheduling information or intervals for cleaning, adjusting, inspecting, testing, and lubricating each part of the engine or APU. – You should include in your maintenance manual the degree of inspection, the applicable wear tolerances, and the work required when the engine or APU is in the shop.

维修计划 • FAA批准的可靠性方案 – 根据 AC 120 -17, Maintenance Control by Reliability Methods, FAA发展了可靠性控制和维修的概念。包括： • • • data collection and analysis, corrective action, statistical performance standards, data display and reporting, scheduled maintenance adjustments, and process changes. – AC 120 -17 定义的可靠性接受水平是保持部件失效率低于之前设 定的标准 – 但是, AC 120 -17并不能对MSG 3的维修任务进 行验证
