What types of changes are classified as Non-mandatory MWOs?

Non-mandatory MWOs (Modification Work Orders) refer to modifications that are not immediately required for safety or operational effectiveness but can provide enhancements or improvements to equipment or systems. The correct answer focuses on minor alterations and special purpose modifications, which fit this definition well.

These types of changes do not have the urgency associated with critical upgrades, emergency modifications, or major repairs that are essential for maintaining safety or integrity. Instead, they are considered beneficial for performance or capability but do not pose an immediate risk if not implemented. Such modifications can also be optional, allowing operators to choose whether or not to adopt them based on their specific needs or operational context.
