Part 42 Manual of Standards

The two CASR Part 42 legislative documents are CASR Part 42 and the Part 42 Manual of Standards (MOS).

The MOS covers many airworthiness management matters including the delineation of which aircraft are designated as small or large, requirements for maintenance and reliability programs, and CAMO requirements.

For CASR Subpart 42.G, the MOS specifies the requirements for approval as a CAMO, including requirements for an organisation’s:

• Exposition
• Facilities and equipment
• Managers and other employees, and their qualifications
• A quality management system
• Writing procedures for carrying out maintenance
• Instructions for continuing airworthiness including maintenance data
• Records, and
  
• Procedures for making changes to the organisation that are not significant changes
