ATR72MEL最低设备清单1-00
页数：1
批准日期：03.07
前 言1．概述：
飞机定型时，要求飞机在飞行中所有所需设备都应工作正常，如果某些设备不工作，而又不符合定型类型的要求或不符合某些营运条例的许可范围，这时则不能进行营运飞行。
根据经验，在飞机的设计中使用了不同层次的设计裕度，当工作的设备已能保证安全飞行的情况下，不一定非要每个系统中的每个部件都必须处于工作正常状态，尽管与要求有所偏离，但也允许飞机进行连续或非间隔性营运飞行。
允许的偏离项目都应列在最低设备清单中《MEL》。
主最低设备放行清单《MMEL》由飞机制造厂家提供，并已经法国民航当局的批准。用户可根据主最低设备放行清单来制定自己公司的最低设备清单，用户在制定最低设备清单时，一定要考虑自己公司飞机上的一些特定设备和使用条例，用户制定的最低设备清单必须提交有关当局进行审批。
用户不能直接把MMEL用做MEL，因为在MMEL中没有考虑如下事项：
——用户所处国家对飞机的使用和营运要求。
——特定的飞行使用。
——飞机交货后，用户对飞机设备的增加或改装。
出于简洁，MMEL中不包括：
——明显所需项目，如机翼、方向舵、襟翼、发动机、
起落架等。
——不影响飞机适航性的项目，如厨房设备，旅客方便
设备等。
不管怎样，与适航性相关的设备以及飞机营运条例所要求的设备，尽管没有列在MEL中，但这些设备每次飞行时都必须工作正常。
注意1：在缺某些结构件的情况下，应按《飞行手册》中的有关规定放行飞机。（第七章，状态偏离放行清单）。
注意2：在某些系统失效的情况下，应按《飞行手册》中的有关规定放行飞机。（第7.02.00章增补部分）。
以警告标牌形式出现的条件和限制，维修程序，机组操作程序以及其它限制条件都应编写在MEL中，以确保飞行安全。
某些项目的故障在排除和修理之前，MEL允许飞机带着某些有故障的设备飞行一定时间，但用户还是应尽早地排除故障和修理。当飞机带着故障飞行时，为了保证安全性和可靠性，MEL中给出了一些限制条件。当飞机具有某种缺陷或故障时，用户应根据MEL中的要求放行飞机，发现某些设备不能正常工作后，应将这些情况填写在维修记录/飞行记录本中（不得晚于下次飞行前），如某些设备故障，用户不能因为MEL中有了某些限制就放松了对飞机在这种情况下运营的安全性考虑。
用户应负责制定某些必要的使用控制来保证安全水平，且评估飞机新的营运、使用范围，同时也要考虑到当飞机带着某些不工作的设备飞行时，其它工作正常的系统和部件也有可能在飞行中出现故障，尽管在MEL中也考虑了不工作项目对飞机使用的影响，但不能完全地把所有这种组合都考虑进去。在多个项目不工作的情况下飞行时，必须考虑这些项目的内在联系，相互影响和机组人员的工作负荷。

页数：2
批准日期：03.06
用户应建立可控和有效的维修大纲，包括部件、人员、设备、程序以及保证修复的时间计划。在此大纲中应注意对维修缺陷的认识和处理方法。
MEL中的限制条件不能偏离《飞行手册》、应急程序、或适航指令中的要求，MEL中的限制条件不能低于MMEL。

—第1栏：根据ATA章节号标明系统和项目
—第2栏：定义修理间隔类型
—第3栏：装机数量
—第4栏：按MEL放行时所需设备数量（工作正常的设备）
—第5栏：按MEL放行时所要求的条件和备注
—第6栏：“有效范围”，指该MEL项目或条款的适用范围。本栏以数字代码代表适用飞机。若本栏空白，表示适用范围为全部飞机。本栏若以数字表示，则表示适用飞机的起始范围。如22、23、25表示有效代码为22、23、25的3架飞机，即ATR3022、3023、3025三架飞机。
—修理间隔分类：
注：以下分类标准与中国民航总局发328号文件的修理间隔分类标准存在不一致时，以中国民航总局发328号文件的分类标准为准。
A类：
无统一的时间间隔，这些项目应修复：
(i)
下次飞行前，或
(ii)
在MMEL第5栏中给出的规定时间内。
时间应从故障记录到维修记录/飞行记录本中计起。
B类：
属于此类的项目应在3个连续日历天内（72小时）修复，不计反映故障的那一天。
C类：
属于此类的项目应在10个连续日历天内（240小时）修复，不计反映故障的那一天。
D类：
无规定的时间间隔限制。
属于此类的项目，用户可根据自己的决定，对项目解除功能。
拆去或安装到飞机上。

注释：
1—第5栏中的*号，表示对不工作的部件或组件应在驾驶舱内挂警告标牌。
2—第5栏中的工作标记（O）：机组操作程序要求。
第5栏中的工作标记（m）；维修程序要求。
如飞机要带故障项目飞行时，应制定相应的程序并发布。
3—第3和第4栏中的“—”号：装机数量没有确定。
4—放行需要不同的限制条件时，将用1），2），3）……表示。
5—本清单中一些术语的定义：
A、－“VMC飞行条件”：大气环境符合本次飞行的目视气象条件。
B、－“结冰情况”：在这种大气环境里飞行时，有可能在飞机或发动机上出现结冰。
C、－“不工作”（失效）（故障）：任何时候，只要系统或组件不能完成它应有的功能时，或在其设计限制和容差内不能连惯的发挥它的功能时，该系统或组件就被认为是“不工作”（故障）、（失效）。
D、—“ETOPS”（双发飞机延程飞行）：按双发飞机延程飞行要求执行。
E、—“飞行日”24小时（从一个子夜到另一个子夜）内相关的飞机至少有一次飞行。
F、—“跨水域飞行”：指距离最近海岸线水平距离超过50海里的水上飞行。
G、－“货运构型”:指安装货运装置的ATR飞机从事货运飞行，如果是通过STC进行的改装，必须依据STC修改MEL.
