Borescope also is used in regular engine component checks for engine performance monitoring. 4.1.1.2 发动机孔探检查监控方案的目的是为了持续监控发动机孔探检查发现的故障/缺陷的变化情况并在必要时能及时制定纠正措施。 本方案将确保发动机孔探检查所发现的故障/缺陷在维护手册允许范围内。 4.1.1.2 The engine borescope inspection (BSI) monitoring program is to monitor the failure and defects found during engine BSI and take timely actions to ensure the failures and defects are within the limitation of the Maintenance Manual.4.1.1.3 孔探检查监控方案的流程图见图4-1。 4.1.3 The flowchart illustrating borescope inspection monitoring program is followed (see flow chart 4-1). 流程图 4-1 孔探检查监控方案流程 FLOW CHART 4-1 BORESCOPE-INSPECTION MONITORING FLOW CHART  4.1.2 数据收集4.1.2 Data Collection4.1.2.1 发动机的孔探工作由孔探人员负责完成。避免安排同一孔探人员长期进行同一发动机的孔探工作。4.1.2.1 Engine borescope inspection is done by borescope inspector. The same inspector should not do the inspection on the same engine in a long time.4.1.2.2 孔探有两种情况：一种是《维修方案》中的例行孔探，它要求在相应的定检中完成; 另一种是按相关工卡孔探检查发动机，它要求在规定的期限内完成。 4.1.2.2 Borescope inspections are generated by two conditions, one is routine Borescope inspection according to Maintenance Schedule, and another is non-routine Borescope inspection according to task card. 4.1.2.3孔探人员应对每次所做的孔探检查填写电子版的发动机孔探检查报告单(见附录1中图4-1)。孔探状况收集和控制人员负责收集和保存孔探检查报告单，并在孔探检查后24小时内将孔探检查报告单上传到“发动机在线”网站，如需延期，需向发动机管理中心申请。 4.1.2.3 The each Borescope Inspection that had been done should be registered as the electron revision Engine Borescope Inspection Report (see Appendix 1 FIGURE 4-1) by the
