Which regulations govern the supervision of progressive inspections?

The supervision of progressive inspections is governed by 14 CFR Sections 43.13 and 43.15. These sections outline the general maintenance requirements and standards necessary for performing maintenance, preventive maintenance, and alterations on aircraft. Specifically, Section 43.13 emphasizes that all maintenance actions must be performed in accordance with accepted standards, ensuring that work is done correctly and safely. Section 43.15 focuses on the necessity for inspections to be completed in accordance with the instructions provided by the manufacturer or other accepted practices.

Progressive inspections, which are phased over a specific time or usage interval, are subject to these regulations to make sure they are conducted properly and that the aircraft remains airworthy. This regulatory framework is crucial for ensuring that the methods and procedures utilized during inspections are thorough, thereby maintaining safety standards in the aviation industry.
