What is involved in an engine changeout?

The process of an engine changeout specifically involves removing a faulty engine from the aircraft and installing a replacement engine. This procedure is essential when an engine has experienced a failure or is deemed unserviceable. The changeout typically requires careful adherence to maintenance manuals and manufacturer specifications to ensure that the new engine is installed correctly and that all necessary connections, such as fuel lines, electrical systems, and structural supports, are secure.

In contrast, the other options do not accurately describe the complete scope of a changeout. Minor repairs to the engine refers to less significant maintenance activities rather than the removal and replacement of the entire engine. Remapping the engine's electronic systems and upgrading the engine's software are specific tasks that may be performed during a routine maintenance cycle or as part of modifications, but they do not constitute the primary actions taken during an engine changeout.
