MANUALS > Technical Records > Technical Records Module > Technical Records, Update Menu > Defect Report > Defect Report Detail > Defect Report Detail, General Tab > Corrosion/Damage & Repair Button, via Defect Report Detail, General Tab

The Corrosion/Damage & Repair window deals with the aircraft's Corrosion/Damage & Repair (CDR) which is part of the maintenance program, especially in cases of aging aircraft. It is often treated as a separate aspect of aircraft maintenance. A baseline program is published in the manufacturer's document for every airplane model. As an operator, you may adopt the program in total or develop CDRs tailored to your particular operation.

This button is security-controlled via Technical Records/ Update/ Defect Report/ Corrosion, Damage and Repair. For additional information, refer to the Security Explorer via the System Administration Training Manual.

CDR tasks are mainly structural inspections and often require extensive work to allow access to the inspection area. The area is cleaned and inspected - if required with non-destructive inspection. If necessary, any corrosion or damage is repaired. Prior to close access, the area is treated with corrosion protection compounds.

However, during the day to day operations, technicians may also identify CDR and associate their findings to the Defect Report when the problem is located.

From the Defect Report Detail, General tab, select the Corrosion/Damage & Repair button.

The system displays the Corrosion Damage Repair window:
