Question 6Gas Turbine - 1st Asst/Chief

The correct answer is B) Start the engine to dry it out. After an off-line water wash of a gas turbine engine, the last step is to start the engine to dry it out. This is necessary to prevent corrosion and ensure the engine is ready for operation. The other options are incorrect: A) Opening the Variable Stator vanes is not the last step, as this would be done as part of the water wash procedure, not after. C) Releasing the gas generator brake is also not the final step, as this would be done to prepare the engine for starting, not after the drying process. D) Securing the starting system is not the correct final step, as the engine needs to be started to complete the drying process.
