 为使盖板受力均匀,需对称紧固螺钉或螺栓。
 紧固力矩根据AMM 手册要求确定。
 有密封要求的盖板需要涂胶。
 安装结束前,应复检没有漏装螺丝钉,而且全部螺丝钉都拧紧了,必要时用轻
轻敲击检查安装质量。
B. 盖板安装的步骤
(1) Examine the sealing compound on all sides of the aperture and the access panel for
signs of damage(若无密封要求,此步只做简单清洁工作即可)
If you have to replace the sealing compound, continue as follows:
WARNING: METHYL-ETHYL-KETONE IS A FLAMMABLE MATERIAL AND IS DANGEROUS
TO YOUR HEALTH. MAKE SURE THERE IS A GOOD FLOW OF AIR AND PUT ON
GLOVES.
CAUTION: DO NOT GET METHYL-ETHYL-KETON E ON ADHESIVE- BONDED JOINTS
BECAUSE IT CAN DAMAGE THE BOND.
CAUTION: DO NOT LET METHYL-ETHYL-KETON E TOUCH PAINTED SURFACES FOR
LONGER THAN NECESSARY.
(a) Carefully remove the old sealing compound with a correct tool (wood or plastic
spatula).
(b) Soak a clean, lint free cloth in ( methyl-ethyl-ketone ) and carefully clean the
surface you have to seal, to remove all signs of the old seal. Let the surface dry in
the air.
(c) Apply ( adhesive tape ) to give protection to the area you have to seal.
(d) Apply ( release agent ) to the surface on the panel you have to seal and let the
surface dry for 15 to 20 minutes.
(e) Polish the release agent with a clean, soft cloth until the surface has a constant
gloss.
(f) Mix sufficient (sealing compound ) as given in the manufacturer’s instructions.

(g) Smoothly apply the sealing compound to the surface you have to seal. Be careful
you keep the sealing compound away from thread tapings and make sure there are
no bubbles in the compound.
(h) Install and attach the panel before the pot life expires and make sure the sealing
compound comes out smoothly at the edges of the joint.
(i) After the cure time has expired, carefully trim the unwanted sealing compound from
the edges and thread tapings with a plastic knife.
(j) Examine the sealing compound. It must be smooth and have no defects or cracks.
(2) Install and attach the panel.
(a) Clean the interface of the access panel and the wing skin with a lint-free cloth.
(b) (b) Examine for damage the interfaces of:
 the access panel
 the special seal
 the wing skin
 the screw holes in the access panel .
CAUTION: YOU MUST FOLLOW THESE STEPS ACCURATELY. THIS WILL PREVENT
DAMAGE TO THE SCREWS, THE INTERFACES OF THE ACCESS PANEL AND THEWING
SKIN.
(c) Make sure the work area is clean and clear of tools and equipment before you install
the access panel .
(d) Make sure the aircraft is in the same configuration as for the removal.

(e) (e) Put the access panel in the installation position on the wing.
WARNING: MAKE SURE THAT THE ACCESS PANEL IS CORRECTLY ELECTRICALLY
BONDED WITH TWO SCREWS TO THE WING STRUCTURE.
(f) Install the screws .
(g) Torque the screws to 9.4 to 11.4 Nm (83 to 97 lbf in.)
(h) Examine the access panel you have installed for leakage.
(3)Job Close-up
(a)Install the components that have been removed.
(b) Make sure the work area is clean and clear of tools and other items.
(c) Remove the access platform.
2.2 特殊螺丝钉及其紧固盖板的拆装
2.2.1 特殊螺丝钉及其紧固盖板的拆卸
A.盖板拆卸的要点
 正确选择螺刀头形状和大小或扳手、套筒尺寸。
 要先慢速拧松螺钉或螺栓,再用快速工具(比如电枪)将螺钉或螺栓拆
下。
 有些特殊螺钉只须正向转动(拧紧)或反向转动(拧松)90 度即可。
 有的盖板固定时使用不同的螺钉,拆卸时需要作好标记。
B. 盖板安装的步骤
2.2.2 普通螺丝钉及其紧固盖板的安装
A. 特殊螺丝钉的认识

(1) 此种紧固件的结构共由四部分组成:螺钉、锁紧指示环、托把及托
把锁块,此外在盖板上有一个锁钩;
(2) 拆装此种盖板时,用螺刀正向或反向逆转动螺钉90 度,即可完成拧
紧或拧松的过程。
B. 盖板拆装注意事项
(1) 安装此盖板前首先要检查螺钉、锁紧指示环、托把及托把锁块四个
部件是否完好,是否有磨损,如果发现有损坏则视情更换损坏的部
件。
(2) 安装时用螺刀顺时针方向转动螺钉90 度,使锁紧指示环上的凹槽垂
直于盖板边缘(如下图),最后将螺钉拧紧。
(3) 拆下此盖板时用螺刀逆时针方向转动螺钉90 度,使锁紧指示环上的
凹槽平行于盖板边缘,如果锁紧指示环上的凹槽仍然垂直于盖板边
缘,可以继续拧松螺钉,然后用一字螺刀将锁紧指示环上的凹槽拨
到使其与盖板边缘相平行状态(如下图)。
注意:如果螺钉旋出过多,在安装盖板时可能造成即使凹槽指示正确,但
实际拖把仍未到位的情况,请工作者安装前确认拖把没有因螺钉旋出过多
而从叉形锁紧指示环中脱开。
C. 此种盖板安装的注意事项
(1) 在盖板上有一个锁钩(如下图),此锁钩是为了防止旋转式螺母锁
紧机构全部失效以后盖板在空中脱落打伤其他部位的,所以在维护
工作中建议大家在拆下旋转式螺母锁紧机构以后,不要将锁钩取下。
(2) 如果由于工作需要需将此盖板彻底取下,在安装时要注意不要忘记
将锁钩锁上。

(3) 如何检查此类盖板的安装牢固性
将盖板上的旋转式螺母锁紧机构全部锁紧以后,应用手或磁性根部
敲击盖板上的旋转式螺母锁紧机构,确定没有任何松动的现象。
2.3 锁扣勤务盖板的开关
2.3.1 锁扣及其紧固盖板的认识
(2)发动机包皮锁扣图片暂无
2.3.2 锁扣盖板开关的注意事项
(1) 打开盖板前,确认锁扣已经完全打开;
(2) 关闭盖板后,确认锁扣已经完全扣好。可用手轻轻敲击的方法检查。
3.施工(操作)注意事项
(1) 对于用普通螺钉安装的盖板,拆装螺钉所选择的螺刀头形状、大小;
拆下的螺丝钉必须用布包集中保存;安装盖板后,必须复检盖板螺没
有漏装,漏加力矩的情况;
(2) 对于特殊螺丝钉及锁扣盖板,安装后必须用手拍打盖板,以检查是否
真正安装到位,锁好。
(1)普通勤务盖板锁扣
