Abstract

Helikopter merupakan salah satu alat transportasi udara yang paling banyak digunakan karena berbagai keunggulannya. Untuk menjaga helikopter dalam kondisi baik dan laik terbang, perlu diperhatikan faktor perawatan (maintenance) dimana risiko mungkin terjadi. Untuk mencegah risiko kegagalan dapat dilakukan manajemen risiko, salah satunya adalah metode Failure Mode and Effect Analysis (FMEA). Berdasarkan hasil analisis FMEA, terdapat 14 mode kegagalan yang berpotensi terjadi pada sistem tail rotor hub and blade helikopter Bell 407 yaitu over stake, spherical bearing play, bearing play, pitting, crumbling, bolt pitting, extruding, sheeting, bushing wornout, delamination, blade delamination, voids, cracks, dan korosi dengan nilai RPN secara berturut-turut adalah 500, 168, 168, 81, 54, 54, 42, 42, 36, 27, 20, 10, 10, dan 4. Berdasarkan nilai RPN tersebut, dibuat diagram pareto untuk menentukan prioritas risiko yang perlu dimitigasi dan lima mode kegagalan yang diidentifikasi sebagai prioritas yaitu over stake, spherical bearing play, bearing play, pitting, dan crumbling.

Helicopters are one of the most widely used air transportation because of their various advantages. To keep the helicopter in good condition and airworthy, it is necessary to pay attention to the maintenance factor where the risk may occur. To prevent the risk of failure, risk management can be carried out, one of which is the Failure Mode and Effect Analysis (FMEA) method. Based on the results of FMEA analysis, there are 14 failure modes that have the potential to occur in the Bell 407 helicopter tail rotor hub and blade system, namely over stake, spherical bearing play, bearing play, pitting, crumbling, bolt pitting, extruding, sheeting, bushing worn out, delamination, blade delamination, voids, cracks, and corrosion with RPN values of 500, 168, 168, 81, 54, 54, 42, 42, 36, 27, 20, 10, 10, and 4. Pareto diagrams are made to determine the priority of risks that need to be mitigated and five failure modes are identified as priorities, namely over stake, spherical bearing play, bearing play, pitting, and crumbling.
