This Technical Order (TO) establishes policy and provides procedures for managing repair cycle assets. Inherent in the management of repair cycle assets is the responsibility to seek ways to maximize equipment repair capability at all levels of maintenance. This TO implements the policy established in AFMAN 23-110, Volume 2, Part 2, USAF Supply Manual, and AFI 21-101, Aerospace Equipment Maintenance Management. Procedures are also included to integrate maintenance and supply data. Each demand upon supply for a serviceable item receives a document number which maintenance records on the AFTO Form 350, Reparable Item Processing Tag. This merging of data provides the means to (1) Identify the repair cycle assets, (2) Determine, establish, and adjust stock levels, and (3) Compute world-wide spares requirements for reparable items.
