2. List and record possible causes.
3. Devise checks.
4. Conduct checks in a logical order to
determine the cause.
5. Consider the remaining service life of
components against the cost of parts and
labor necessary to replace them.
6. Make the necessary repair.
7. Recheck to ensure that nothing has been
overlooked.
8. Functionally test the new part in its
system.
