Figure 1). 检查发动机进气道消音板（参考图1）A. Preparation of the Air Intake Acoustic Panels. 检查进气道消音板准备工作。Clean the surface of the air intake cowl acoustic panels with an OMat 2/101 lint-free cloth moistened with OMat 150 Acetone solvent. Make sure you use OMat 2/114 lint-free gloves whenyou clean components.使用不掉毛抹布OMat 2/101蘸取适量清洁剂OMat 150，对进气道消音板进行擦拭。并确认在施工前戴好防护手套OMat 2/114。NOTE: Make sure you wipe the surface of the parts before the solvent evaporates. 注 释：确认在清洁剂挥发前擦处表面清洁剂。B. Inspection of the Air Intake Acoustic Panels. 检查进气道消音板Inspect the complete surface of all three air intake cowl acoustic panels for disbond between theacoustic panel lining and Nomex Honeycomb core using the tap test procedure that follows: 检查3块进气道消音板全部表面，通过敲击方法，查看表层和蜂窝结构间有无分层，步骤如下：NOTE: It is easier to check for areas of disbond if you divide each panel into two sections(section 1 and section 2) as shown. Refer to Figure 1 sheet 2.注 释：参考图1-2，将消音板分为区域1和区域2，将有利于对整个消音板进行检查。(1). Apply masking tape (OMat 237 or suitable alternative) to make a 25mm (1inch)border on the front face of each acoustic panel taken from the edges of the acoustic area (refer to Figure 1 sheet 1). Do steps (a) thru (d) and inspect the marked area thoroughly.使用标记胶带（OMat 237或等同胶带），在距离每块消音板的消音区域四周边缘25mm(1inch)处做好标记（参考图1-1）。对于该区域，执行（a）-（d）检查。a). Tap test at intervals of 20 mm (approximately 0.75in) across the full surface of each airintake cowl acoustic panel with the ball end of the tap-testing tool.对于每块消音板，在该区域，使用检查工具，每隔20mm敲击检查一次。b). Take note of any change of pitch in the sound given out from the air intake cowlacoustic panels. A change of pitch indicates a disbond at that location.特别注意敲击时发出声音音调的变化。音调的变化意味着在该区域存在分层。NOTE: Expanded foam adhesive is used to bond the materials around the edges of the panelsand this can cause a different sound during the tap test. 注 释:多出的粘结剂用于粘牢消音板边缘的材料，可能导致测试过程中音调的变化。c). If a disbond is detected, tap test at intervals of 12mm (approximately 0.5 inch) acrossthe full surface of the part to determine the dimensions of the delamination or disbond.如果发现脱胶，缩小敲击检查间隔到12mm，并以此间隔进行后续检查，以确认具体分层或脱胶的面积。d). Use OMat 262 marking pen to make a mark on the air intake cowl around any areas ofdisbond between the acoustic panel lining and the Nomex honeycomb core.对于表层和蜂窝结构脱胶或分层的区域，使用OMat 262记号笔在消音板上进行标记。(2) Apply masking tape (OMat 237 or suitable alternative) to make a grid pattern of150mm (6 inch) squares on the front face of each acoustic panel. Do steps (a) thru (d)and inspect the marked area thoroughly.使用标记胶带（OMat 237或等同胶带），在每块消音板上标记出边长为150mm (6 inch)的方格。对于该区域，执行（a）-（d）检查。a). Tap test at intervals of 20 mm (approximately 0.75in) across the full surface of each airintake cowl acoustic panel with the ball end of the tap-testing tool.对于每块消音板，在该区域，使用检查攻击，每隔20mm敲击检查一次。b). Take note of any change of pitch in the sound given out from the air intake cowlacoustic panels. A change of pitch indicates a disbond at that location.特别注意敲击时发出声音音调的变化。音调的变化意味着在该区域存在分层。NOTE: Expanded foam adhesive is used to bond the materials around the edges of the panelsand this can cause a different sound during the tap test. 注 释:多出的粘结剂用于粘牢消音板边缘的材料，可能导致测试工程中音调的变化。c). If a disbond is detected, tap test at intervals of 12mm (approximately 0.5 inch) acrossthe full surface of the part to determine the dimensions of the delamination or disbond.如果发现脱胶，缩小敲击检查间隔到12mm，并以此间隔进行后续检查，以确认具体分层或脱胶的面积。d). Use OMat 262 marking pen to make a mark on the air intake cowl around any areas ofdisbond between the acoustic panel lining and the Nomex honeycomb core.对于表层和蜂窝结构脱胶或分层的区域，使用OMat 262记号笔在消音板上进行标记。2. Permitted damage limits criteria 允许损伤标准A.
