Master Repairable Item
List (MRIL)
The Navy’s Master Repairable Item List (MRIL) is
provided to identify Navy-managed mandatory turn-in
repairable items. It also provides shipping instructions
for unserviceable repairables that must be turned in to a
designated repair facility.
The MRIL consists of two basic parts: Part I—
Listing of Items and Part II—Shipping Addresses. Part I
(fig. 7-6) lists all repairables that are no longer
serviceable and gives disposition instructions. Usually,
unserviceable components are shipped to a designated
repair facility or collection point. The repairables are
listed in sequence by the last 9 characters of their
13-character NSN or NICN. Part I also lists the shipping
code of the activity to which an unserviceable repairable
must be shipped. Part II (fig. 7-7) lists the shipping
addresses of designated repair activities (military and
civilian contractors) and collection points to which the
repairables are to be sent.
