Gives a procedure that can be used to predict maintainability parameters of avionics, ground & shipboard electronics at the organisational, intermediate and depot levels of maintenance. Coverage includes: basic parameters of measurement; correlation between predicted and observed values; corrective maintenance task time analysis; total maintenance task time analysis; replacement concept definition.

The purpose of this Maintainability Prediction Handbook is to familiarize project managers and design engineers with current maintainability prediction procedures. To achieve this objective, particular care has been exercised in selecting and including only those procedures which are currently used in predicting the maintainability of equipment and systems.
