7．维修间隔 Maintenance Interval

在CAMP中大多数例行检查工作的执行间隔按照“字母检查”给定，例如：1A,2A,4A,8A,1C等。“字母检查”和其它检查的定义如下：

The majority of scheduled maintenance tasks listed in this CAMP identify the check-Interval of accomplishment in terms of a letter

1A,2A,4A,8A,1C, letter checks and the other checks are defined as follows:

A.航线维护:Line Maintenance

a.航前/过站检查(PF/T)

pre-flight/Transit-check(PF/T)

在每日的第一次飞行前和所有航站航线上应该执行航前/过站检查。航前/过站检查的基本工作是“绕飞机一周”检查。目视检查飞机内外是否有明显的损坏，渗漏，缺件，各种设备是否工作正常，按需做勤务工作，机内清洁工作，排除机组和地勤人员反映的影响放飞的故障。这些工作是在客机坪和停机坪上执行。

The pre-flight/transit-check(PF/T)shall be performed before the first flight of each day and at all eroute stops. It is basically a ‘walk-around' inspection

of the aircraft interior and exterior for obvious damage leaks, missing parts, proper operating equipment and security of attachment, servicing as

required, cleaning of cabin, rectification of NO-GO flight/ground complaints. Work to be performed at ramp position.

b.航后检查(AF)

After-flight check(AF)

对营运中的飞机，每24小时之内必须执行一次航后检查，即使在特别的情况下，检查间隔也不能超过48小时。在航后检查中，排除空/地勤人员反映的故障及保留故障，按需进行机内外清洁工作，这些工作是在指定航站执行。

After-flight check shall be performed at least once every 24 hours while aircraft is in service. However, if exceptiond circumstances arise the in-service

time between a check item shall not exceed 48 elapsed hours. During AF check, rectify flight/ground complaints and deferred defects, clean the interior

and exterior if required. Work to be performed at an assigned station.

说明： B737-300 MPD中所规定的DAILY CHECK项目在CAMP中规定为航后检查项目。

8.飞机称重和平衡: Aircraft Weight & Balance

根据制造厂的技术说明书，所有飞机都应称重，以确定其空机重量和空机重心。通常在下列情况下进行称重:

All aircraft shall be weighed to determine the Empty Weight and Empty CG. Per the manufacturer s instructions. In general, aircraft shall be

weighed:

a).不超过4年,进行一次称重。

At intervals not exceeding 4years.

b).在实施大范围的改装和/或修理后，中国国际航空公司/飞机维修单位从安全方面考虑，认为应当重新称重时应重新称重。(除非重量和重心的变化可以被计算出)

After extensive modification and /or repair, Air China /Aircraft Maintenance Unit considers it should be reweigh in the interest safety.(unless the

weight and C.G. Change could be calculated)

c)签发合格证 Issue of Certification

飞机每次称重后，飞机维修单位工程部门应当填写一份飞机重量与平衡报告，该报告由持有该机型维修执照的责任工程师签署，并送国航有关部门。

Each time an aircraft is weighted, an aircraft weight and balance report shall be completed and certified by a responsible engineer with a

maintenance license for the aircraft type in Aircraft Maintenance Unit Engineering. The report shall be distributed to Air China associated

department.

9.标准飞行时间的定义 Definition of Standard Flight Time

针对定期维护检查的计划而言“标准飞行时间”一词的定义如下:

with reference to the planning procedures for scheduled maintenance checks the term standard Flight Time is defined as follows:

维修间隔时限规定的维修检查不得超过计划飞行(1)终了的时限。

The maintenance checks specified in interval limitation must not exceed the end of a scheduled flight program (1).

但是，如飞行计划要超出正常的飞行时间(2)，相应地，维修时间就会因一些特殊情况超出飞机航行部门的控制(如:备降遇到强逆风，等待(空中)，延误，航班取消而顺延)。维护检查计划(以飞行小时或日历时间计算)就会超出时限，以使飞机能完成飞行计划直至到达此特定飞行计划规定的维修航站(3)。

If, however, a flight program should exceed the normal standard flight time (2), respectively the scheduled layover time due to events that are

beyond the control of the Aircraft Routing Dept. (e.g. alternate landings, strong head-winds, holdings delays, cancellations), then the

maintenance checks (flight hours or calendar time) may be exceeded as far as is necessary for the aircraft to complete its flight program until

reaching the maintenance station (3) determined for this particular flight program.

解释: Explanations:

(1).飞行计划: 是指飞机由事先规定的维修场站起飞，经沿途各航站，再飞回该维修场站，或飞到另一个予定维修场站。

. Flight Program: Is a flight of a certain aircraft from a certain predetermined maintenance station, via several line stations, back to that maintenance

station, or to another predetermined maintenance station.

(2).正常标准飞行时间: 是指提前计算好的飞行时间，以其作为控制飞机航行及使用的基准。

. Normal Standard Flight Time: Is the time which has been calculated beforehand and will serve as a basis for aircraft routing and operational control.

(3).维修航站：本文所指的航站是指可以进行勤务维护和更高级别检查的航站。

. Maintenance Station: In this context is a station where service checks and higher checks are performed.

Example: inspection of structural parts for cracks or corrosion, etc ;

“状态监控” “CONDITION MONITORING”(CM)

对于即没有定时，也没有视情维修为主要维修程序的项目，可以列入监控计划进行状态监控。“状态监控”的意思是没有规定预防工作(定时或视情检查)，组件或零件一直可使用到出现故障时为止。“状态监控”的主要目的是分析可能或即将发生的故障，以确定是否需采取技术措施，达到保证系统和飞机的连续适航。

For items that have neither hard time limits nor on condition maintenance as their primary maintenance process, condition monitoring is accomplished by

the monitoring program. Condition monitoring means, that no preventive task (hard time or OC check) is defined and that the unit or part is to analyze

the malfunctions to indicate whether some technical actions are required to assure the continuous airworthiness of the system and the aircraft.

“无” “NONE” 如某部件不属于上述所规定的维修方案则属于“无”

-II区域和结构检查 ZONE AND STRUCTURE

区域检查方案 ZONAL INSPECTION PROGRAM

CAMP.包括许多区域检查要求。这些区域检查出于两个主要目的：

l)通过充分的区域检查工作，对各区内所有系统和结构项目的总体状况及连接牢靠性进行评价。

2)将为重要维护项目(MSI)或重要结构项目(SSI)制定的一系列一般目视检查工作组合到一个或多个区域检查工作内。

每个区域检查包括一般目视检查，以及必要时对包括在所定义区域内的可接近系统和结构项目的总体状况和连接牢靠性进行结构检查。这包括检查有无明显性能下降，如管路的擦伤、导管和支撑的松动、导线的损伤、钢索和凸轮的磨损、渗漏、排放系统不畅通等和有无腐蚀和可能导致腐蚀的损伤等等。

The CAMP. contains a number of zonal inspection requirements. The zonal inspection serve two primary purpose:

1). To assess the general condition and security of attachment of all system and structure items contained in each zone by use of adequate zonal

inspection tasks.

2). To provide packing a number of general visual inspection tasks prepared for maintenance significant items (MSI) or structurally significant items(SSI)

into one or more zonal tasks.

Each zonal inspection shall include a general visual and, if required, a physical check of general condition and security of attachment of the accessible

system and structure items contained in the defined zone, This inspection includes a check for evidence of degradation such as chafing of tubing, loose

ducts or supports, writing damage, cable and pulley wear, fluid leaks, inadequate drainage, etc. And corrosion or damage which could lead to corrosion ,

etc.

结构抽样检查 STRUCTURE INSPECTION SAMPLING

A.抽样检查方案以年度或飞行小时为基础，对每一重要结构项目进行抽样检查。初始抽样方案将包括CAMP.中规定的那些重要结构项目。其他重要结构项目，在AIR CHINA或波音公司或其他用户的经验表明有必要进行检查时，要加到这一方案中。

A sampling inspection program is established to accomplish an internal sample inspection of each structural significant item on an approximately yearly

or flight hours basis. The initial sampling program will consist of those structural significant items specified in the CAMP. Additional structural

significant items will be added to the program whenever AIR CHINA or Boeing or other operators’ experience indicates that an inspection requirement

is necessary.
