Description	Journal: Iop Conference Series: Materials Science and Engineering A gas turbine power plant is the best choice for peak load conditions in power generation. As we know using gas turbine need less time to start and stop operation than a coal-fired power plant. In East Java, Indonesia has 9unit Gas Turbine Power Plant, which usually operates in peak load conditions. In this paper, a study will carry out an investigation based on maintenance data history which since 2010 founded repeatedly crack in the exhaust manifold. Failure Investigation in the exhaust manifold has been carried so that repetitive crack can be handled in the future. The crack location was mapped to found the root cause of failure. Fuel consumption and operation condition was analyzed to find the cause of the crack. Analysis with fluent software found that streamline of flue gas makes a turbulency in the spotted area. Material selection and design no free expansion in the exhaust manifold increase possibility of failure.
