Supplementary Information

It is important that only the current issue, of whichever system is in use is supplied to servicing technicians. This means that the amendment procedures must be carefully monitored (especially the disposal of the out-dated material). The new amendments come with a ‘Letter of Transmittal’, rom the relevant authority, in exactly the same manner as they do with the ‘hard copy’ technical publications.

Because of the need to dispose large amounts of information, it is normal to produce supplementary information in hard copy form as an intermediate source of current information. These issues are in addition to either the film/fiche/CD-ROM systems in use and must be not only carefully monitored, but also well publicised. This ensures that the technicians know that the information contained in the system they are using could possibly contain small items of out-of-date information.
