The appropriate engine maintenance protocol is dependent on many factors such as regional regulations and engine OEMs / shop requirements. To ensure the engine is in optimal working condition, engine parts need to be professionally and thoroughly cleaned for effective non-destructive testing (NDT) inspection and any corresponding engine overhaul or parts replacement activities.
