Section II. DIRECT SUPPORT MAINTENANCE PROCEDURES
This section contains procedures and methods for the repair of the refrigerated container to permit its safe return
to service after minor damage. It does not attempt to describe repairs necessary for return to service after major
damage. Such repairs should be performed only at an approved container repair facility.
For the purpose of this manual, major damage is considered as anything greater than superficial damage to
corner fittings, corner posts, roof stringers, main rails (top and bottom), and underframe. Minor damage is
considered to be damage to isolated portions of the side panels, front panels, roof assembly, flooring, or
insulation. Damage which requires the repair of large portions of any of these parts of the container are
considered major repair, and should be attempted only at qualified container repair facilities. Repaired
containers should meet all applicable requirements of ISO specifications and the International Convention for
Safe Containers (CSC).
The purpose of any repair is to restore the container to its original structural integrity and thermal efficiency to
enable it to function as an instrument of international transportation. The repair method selected must always be
the most economical for this purpose. Whenever possible, damaged components must be straightened rather
than partly or completely replaced.
After repair, the repaired area should be of equal or greater strength than the original. Materials and parts used
should be of the same or better quality, strength and thickness than those used in the original manufacture. A
proper repair restores the original size and profile of a component.
