During an abort start, what should you do until the ITT decreases to normal range?

• A. Push the starter button
• B. Turn off the ignition
• C. Check the fuel panel switches
• D. Attempt to restart the engine

Answer: (A)

During an abort start, it is critical to manage the engine's temperature to prevent damage. The correct course of action is to continue to push the starter button until the Interstage Turbine Temperature (ITT) decreases to the normal range. This practice helps ensure that the engine begins to cool down appropriately, as continuing to provide ignition during an abort scenario is necessary to alleviate the risk of high ITT levels, which may cause engine damage if not addressed promptly.

Keeping the starter engaged allows for the removal of residual heat and facilitates a decrease in the ITT. Monitoring this temperature is essential for engine health and safety, and waiting until it returns to the normal range before taking further actions is a critical operational guideline. Therefore, maintaining the starter operation under these circumstances is aligned with the NATOPS procedures designed for safe aircraft management.
