This SAE Aerospace Information Report (AIR) outlines comprehensive aircraft flight control system fault isolation methodology that has proven to be effective. The methodology presented in this Information Report has been used in several successful fault isolation efforts on military aircraft.

Purpose:

The purpose of this Information Report is to provide trouble shooting methodology to use for chronic problems that procedures contained in troubleshooting manuals or fault trees fail to fix. This shortcoming may have been due to multiple causal factors or design issues that were not realized by component or airframe manufacturers when the troubleshooting manuals were written.

Field of Application:

This report is written with military aircraft flight control system fault isolation in mind but the principles presented are equally applicable to other aircraft systems.
