CFM56-5B发动机附件齿轮箱(AGB)碳封严常见漏油故障，导致航班延误或取消。在分析AGB碳封严的工作原理和统计历史故障数据的基础上，给出了用威布尔分布计算软时限和预测备件数目的方法，提出了切实有效的改进措施，保证了航班安全、正点。
CFM56-5B髮動機附件齒輪箱(AGB)碳封嚴常見漏油故障，導緻航班延誤或取消。在分析AGB碳封嚴的工作原理和統計歷史故障數據的基礎上，給齣瞭用威佈爾分佈計算軟時限和預測備件數目的方法，提齣瞭切實有效的改進措施，保證瞭航班安全、正點。
CFM56-5B발동궤부건치륜상(AGB)탄봉엄상견루유고장，도치항반연오혹취소。재분석AGB탄봉엄적공작원리화통계역사고장수거적기출상，급출료용위포이분포계산연시한화예측비건수목적방법，제출료절실유효적개진조시，보증료항반안전、정점。
The oil leakage faults of accessory gearbox on the CFM56-5B engine can cause some flights delays and cancellations. The system operation principle are shown. The historical faults data are anglicized. The solution is that how to use Weibull distribution to calculate the soft time life and forecast the spare parts equipments. The effective improvements guarantee the flights safety and on time.
