Abstract
Precooler Control Valve (PCCV) is a component of the engine pneumatic system that functions to regulate the airflow from the fan air to the precooler system. In recent years, on Boeing 737-800 aircraft owned by airline company "XYZ," the Precooler Control Valve with Part Number 3289562-5 has frequently experienced unscheduled removal due to component failure. This study aims to determine the time between failures, identify the most dominant cause of failure, establish the critical lifetime limit of the component, and suggest appropriate corrective actions. Reliability Centered Maintenance (RCM) serves as the fundamental approach for physical maintenance and is a technique used to develop maintenance strategies. This method includes system analysis, FMECA (Failure Modes, Effects, and Criticality Analysis), LTA (Logical Tree Analysis), and the selection of appropriate maintenance actions. Based on the analysis of the Mean Time Between Failures (MTBF) for PCCV with serial numbers 16519, 1711, 17412, and P-121CC, the results were 911.577 hours, 4189.333 hours, 1421.5 hours, and 1372.667 hours, respectively. The FMECA analysis identified that the most dominant cause of PCCV failure is the diaphragm in the actuator linkage assembly, which experiences tearoff, causing the PCCV to become stuck open. The critical component identified is the diaphragm, with the highest RPN (Risk Priority Number) value of 294. Additionally, the LTA analysis categorizes the failure into Category B (Outage Problem), which indicates that the failure can lead to system malfunction. Meanwhile, based on Task Selection, it falls under Category C.D (Condition Directed), meaning that visual inspections and monitoring of specific data must be conducted when symptoms of failure are detected. The reliability test using the Weibull 2-parameter method on the diaphragm indicates a reliability level of 63.147% at 1000 flight hours. Keywords: Precooler Control Valve,MTBF, RCM, FMECA, LTA, Weibull Precooler Control Valve (PCCV) merupakan komponen bagian dari engine pneumatic system yang berfungsi untuk mengatur aliran udara dari fan air menuju precooler system, dalam beberapa tahun terakhir pada pesawat Boeing 737-800 milik perusahaan penerbangan “XYZ” ditemukan Precooler Control Valve dengan Part Number 3289562-5 sering mengalami unschedule removal yang diakibatkan oleh kegagalan pada komponen tersebut. Penelitian ini bertujuan untuk mengetahui, time between failure, penyebab kegagalan yang paling dominan serta mencari batas critical life time komponen dan bagaimana perbaikannya. Reliability Centered Maintenance (RCM) merupakan landasan dasar untuk perawatan fisik dan suatu teknik yang dipakai untuk mengembangkan maintenance, dimana didalam metode tersebut terdapat Analisis sistem, FMECA, LTA dan pemilihan tindakan pemeliharaan yang sesuai. Berdasarkan hasil analisa Mean Time Between Failure pada PCCV dengan SN 16519, 1711, 17412 dan P-121CC yakni berturut – turut 911.577h, 4189.333h, 1421.5h, dan 1372.667h adapun bedasarkan hasil analisis FMECA ditemukan penyebab paling dominan PCCV mengalami kegagalan yaitu diafragm pada actuator linkage assembly yang mengalami tear off sehingga mengakibatkan PCCV stuck open, adapun batas komponen kritikal yakni diafragm dengan nilai RPN tertinggi yakni 294, sedangkan berdasarkan analisa LTA termasuk kedalam kategori B (Outage Problem) dimana dapat mengakibatkan sistem tidak berfungsi, selain itu berdasarkan Task Selection termasuk C.D (Condition Directed) dimana perlu dilakukan pemeriksaan secara visual serta memonitor sejumlah data yang ada apabila ditemukan gejala kerusakan. Adapun hasil pengujian realibility dengan menggunakan weibull 2 parameter pada diafragm yakni dengan tingkat keandalan 63.147% pada 1000 flight hours.
