Failure Mode Effect Analysis (FMEA) Utilization of T-56 Turboprop Engine Turbine
Keywords:Failure Modes, Severity, Risk Priority
Failure Modes and Effects Analysis (FMEA) was used to analyze the failure modes, causes, and effects of the T-56 engine turbine. Failure location and contributing factors were identified and categorized. To give an insight into risk assessment and priority for corrective action, FMEA data were ranked using RPN ranking. From the FMEA matrix, the major failure mode of the T-56 engine turbine was found to be the mechanical damage due to structural failure caused by several factors like erosion and sand ingestion. On the other hand, field data capture the operational and environmental stresses associated with the actual usage conditions and allows for more accurate predictions of the reliability performance of the components. This enables the operators to develop appropriate inspection or replacement programs, and spare part plans based on their own operational and environmental conditions, which result in decreasing maintenance costs and minimizing flight delays and cancellations due to unexpected failures.
