Guide for Shutdown Maintenance

a. Production phase down. As production is phasing down, the using activity, contractor, or Government

activity shall evaluate the production capability of each item of IPE.

(1) The operating capability (condition code) of the item shall be based on general purpose utilization.

Both static and dynamic (analytical) testing shall be performed. Each item to be placed in storage shall also be

mechanically capable of performing the required operation for which it will be retained. In addition to condition coding,

unusual circumstances such as, missing parts, defective components, and/or, erratic operation and malfunctioning that

would affect the manufacturer's design operability shall be noted. This data will provide backup for permanent records

such as the DD Form 1342 (DOD Property Record) maintained by using activity, contractor, or Government activity.

NOTE

Under no circumstances shall the condition code be

established solely on the performance of a specific

repetitive operation.

(2) Shutdown maintenance procedures shall begin as soon as the equipment becomes idle and continues

down the production line until the last item is turned off. Every effort shall be directed toward initiating these progressive

maintenance actions within 48 hours of first machine shutoff. These procedures represent the minimum cleaning and

preservation operations to be performed on plant equipment. They do not, however, release any responsibility for

disassembly when such action is required to meet the minimum requirements of cleaning and preservation for long term

storage. Manufacturing residues are carried by the coolants to cracks and voids throughout the machine. To ensure

adequate removal of these residues, varying degrees of disassembly will be mandatory. Under normal atmospheric

conditions, it is estimated these procedures will provide interim protection for a 30/60 day period, at which time additional

cleaning and preservation are mandatory.

b. Procedures. The following procedures shall be followed when performing shutdown maintenance on each

item of IPE, OPE, special tooling, and special test equipment.

WARNING

Remove all electrical power prior to performing any type

of maintenance or cleaning.
