Sofema Online (SOL) www.sofemaonline.com considers the role of CPCP ADs and the responsibility for updating the Aircraft Maintenance Program (AMP)
Introduction
Each CPCP, whether originally mandated by AD or later incorporated into the MPD for an aircraft, includes certain definitions to lay the groundwork and baselines for the programs.
Corrosion is a progressive condition and generally becomes more serious as it moves deeper into the grain of the affected metal. Therefore, different levels of corrosion are defined: Level 1 being the least serious, Level 2 being increasingly problematic, and Level 3 being the highest. However, these definitions were never standardized, although they are largely well-understood by CAAs, manufacturers, and the industry.
