VIII. MAINTENANCE HISTORY

A. Equipment History

1. Performance Standard

Maintenance standards or procedures clearly define requirements for equipment history for the systems and equipment, including, what information or data to collect, how to record data, and how the data is to be used.

2. Assessment Guidelines

A. Procedures specify requirements for maintenance history, and clearly:

1. Define the method and manner of equipment identification

2. Define the engineering data base or other method for retaining the maintenance history

3. Define the systems and equipment that require documentation and retention of historical data

4. Define the minimum set of information to be included in the data base for each component

B. Procedures clearly define the type of data to be collected and recorded. Accountabilities for data entry are also clearly specified. Some examples of data to include or cross-reference in equipment history are as follows:

1. Corrective maintenance records with failure modes and causes included

2. Appropriate preventive and predictive maintenance records and design modification packages

3. As-found condition during corrective and preventive maintenance

4. Vendor repair information (for example, correspondence on component repairs and modification bulletins)

5. Startup tests and other baseline data

6. Appropriate surveillance test data

7. Calibration data

8. Spare parts information

9. Applicable industry experience information

C. Maintenance history is periodically and systematically reviewed and problems trended. Problems are investigated and corrective actions taken.

D. Maintenance History Database is updated when modifications occur.
