Aircraft Consumables and Rotables Components Parts Catalog

Consumables are items that are frequently replaced; they cannot be restored back to their original state. In aviation, rotables have a comparable definition. Technically, all components of an aircraft have a shelf life; however, the key to them being defined as a consumable or rotable is the amount of time between replacement. Filters are the most common type of consumable used on aircraft; they are used to clean air, water, oil, fuel, etc.
