Description
Summary:The Avionics Management Production Division (WR-ALC/LYP) performs depot maintenance on 125,800 end items per year from more than 20 different aircraft. The basic depot maintenance philosophy has been to test an end item until a faulty function is found and then to narrow the test to identify a failed component. No visibility was given to the prior performance or failure history. No one knew if a particular end item was frequently visiting the depot with the same or similar failures. Test and repair technicians did not have an on-line data collection and retrieval method of documenting and evaluating repair process improvement efforts. An excessive amount of time was spent manually processing data to and from management data systems external to the depot shop. A bar code based end item tracking and data collection system was designed for testing on four avionics production lines. A high priority was given to providing features which would replace paper-based tasks with bar code scanning techniques. Databases and application programs hosted on minicomputers would log test and repair data as it occurred. The accumulated history would immediately be available at terminals in the shop area. End item status, failure and repair data, replaced components, and field generated performance information were included. Information required by external data systems was assimilated and transferred electronically. The project was given the name SMART Shop (Statistical Maintenance And Repair Techniques) This project gives the depot shop an on-line electronic data resource to record test and repair actions as they occur. The data is instantly available at any other workstation to which the end item may go. The technician also has access to information relating to field reports of the end item's performance and all prior test and repair actions. A major feature of the project is tha
