MAKE SURE THERE IS A GOOD FLOW OF AIR AND PUT ON<BR>GLOVES.<BR>CAUTION: DO NOT GET METHYL-ETHYL-KETON E ON ADHESIVE- BONDED JOINTS<BR>BECAUSE IT CAN DAMAGE THE BOND.<BR>CAUTION: DO NOT LET METHYL-ETHYL-KETON E TOUCH PAINTED SURFACES FOR<BR>LONGER THAN NECESSARY.<BR>(a) Carefully remove the old sealing compound with a correct tool (wood or plastic<BR>spatula).<BR>(b) Soak a clean, lint free cloth in ( methyl-ethyl-ketone ) and carefully clean the<BR>surface you have to seal, to remove all signs of the old seal. Let the surface dry in<BR>the air.<BR>(c) Apply ( adhesive tape ) to give protection to the area you have to seal.<BR>(d) Apply ( release agent ) to the surface on the panel you have to seal and let the<BR>surface dry for 15 to 20 minutes.<BR>(e) Polish the release agent with a clean, soft cloth until the surface has a constant<BR>gloss.<BR>(f) Mix sufficient (sealing compound ) as given in the manufacturer’s instructions.<BR>PTR 训练教材<BR>标准施工模块修正日期：2005.6.22<BR>For Training Purpose Only 页码：4<BR>(g) Smoothly apply the sealing compound to the surface you have to seal. Be careful<BR>you keep the sealing compound away from thread tapings and make sure there are<BR>no bubbles in the compound.<BR>(h) Install and attach the panel before the pot life expires and make sure the sealing<BR>compound comes out smoothly at the edges of the joint.<BR>(i) After the cure time has expired, carefully trim the unwanted sealing compound from<BR>the edges and thread tapings with a plastic knife.<BR>(j) Examine the sealing compound. It must be smooth and have no defects or cracks.<BR>(2) Install and attach the panel.<BR>(a) Clean the interface of the access panel and the wing skin with a lint-free cloth.<BR>(b) (b) Examine for damage the interfaces of:<BR> the access panel<BR> the special seal<BR> the wing skin<BR> the screw holes in the access panel .<BR>CAUTION: YOU MUST FOLLOW THESE STEPS ACCURATELY. THIS WILL PREVENT<BR>DAMAGE TO THE SCREWS, THE INTERFACES OF THE ACCESS PANEL AND THEWING<BR>SKIN.<BR>(c) Make sure the work area is clean and clear of tools and equipment before you install<BR>the access panel .<BR>(d) Make sure the aircraft is in the same configuration as for the removal.<BR>PTR 训练教材<BR>标准施工模块修正日期：2005.6.22<BR>For Training Purpose Only 页码：5<BR>(e) (e) Put the access panel in the installation position on the wing.<BR>WARNING: MAKE SURE THAT THE ACCESS PANEL IS CORRECTLY ELECTRICALLY<BR>BONDED WITH TWO SCREWS TO THE WING STRUCTURE.<BR>(f) Install the screws .<BR>(g) Torque the screws to 9.4 to 11.4 Nm (83 to 97 lbf in.)<BR>(h) Examine the access panel you have installed for leakage.<BR>（3）Job Close-up<BR>（a）Install the components that have been removed.<BR>（b） Make sure the work area is clean and clear of tools and other items.<BR>（c） Remove the access platform.<BR>2.2 特殊螺丝钉及其紧固盖板的拆装<BR>2.2.1 特殊螺丝钉及其紧固盖板的拆卸<BR>A.盖板拆卸的要点<BR> 正确选择螺刀头形状和大小或扳手、套筒尺寸。<BR> 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<BR>下。<BR> 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。<BR> 有的盖板固定时使用不同的螺钉，拆卸时需要作好标记。<BR>B. 盖板安装的步骤<BR>2.2.2 普通螺丝钉及其紧固盖板的安装<BR>A. 特殊螺丝钉的认识<BR>PTR 训练教材<BR>标准施工模块修正日期：2005.6.22<BR>For Training Purpose Only 页码：6<BR>（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<BR>把锁块，此外在盖板上有一个锁钩；<BR>（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<BR>紧或拧松的过程。<BR>B. 盖板拆装注意事项<BR>（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<BR>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<BR>件。<BR>（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<BR>直于盖板边缘（如下图），最后将螺钉拧紧。<BR>（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<BR>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<BR>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<BR>到使其与盖板边缘相平行状态（如下图）。<BR>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<BR>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<BR>而从叉形锁紧指示环中脱开。<BR>C. 此种盖板安装的注意事项<BR>（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<BR>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<BR>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。<BR>（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<BR>将锁钩锁上。<BR>PTR 训练教材<BR>标准施工模块修正日期：2005.6.22<BR>For Training Purpose Only 页码：7<BR>（3） 如何检查此类盖板的安装牢固性<BR>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<BR>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。<BR>2.3 锁扣勤务盖板的开关<BR>2.3.1 锁扣及其紧固盖板的认识<BR>（2）发动机包皮锁扣图片暂无<BR>2.3.2 锁扣盖板开关的注意事项<BR>（1） 打开盖板前，确认锁扣已经完全打开；<BR>（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。<BR>3.施工（操作）注意事项<BR>（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；<BR>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<BR>有漏装，漏加力矩的情况；<BR>（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<BR>真正安装到位，锁好。<BR>（1）普通勤务盖板锁扣<BR>PTR 训练教材<BR>标准施工模块修正日期：2005.6.22<BR>For Training Purpose Only 页码：8<BR>4.参考文件<BR>(1) MT737-2003-011<BR>(2) D328-JIC <STRONG><FONT color=#006699>拆装接近盖</FONT></STRONG> 楼主辛苦了~~新人学习学习~~~~ PTR 训练教材 接近盖板的拆装 感谢楼主分享 谢谢分享.好东西. 楼主发帖辛苦，会员学习更需下苦功夫 学习一下，谢谢。 感谢分享，支持楼主
