The TD system is the only authorized method for directing the accomplishment and recording of modification and onetime inspections of NAVAIR equipment. The Naval Air System Command Technical Directive System, NAVAIR 00-25-300, contains the policies and procedures that govern the TD system. TDs are used for the following purposes: Authorize and direct incorporation of approved retrofit changes Issue directions for onetime inspections or precautionary instructions regarding personnel safety and equipment limitations Provide detailed instructions necessary to perform inspections or install retrofit changes and to report and record compliance Provide an official record of inspections and retrofit changes for purposes of technical directive status accounting Respond quickly to safety or urgent operational requirements to incorporate retrofit changes Expeditiously implement minor changes requested by the fleet There are four types of TDs as follows: Formal Change TD.
