The Unending Major Pain
Classifying repairs and alterations as major or minor has been a source of confusion to the Federal Aviation Administration, and therefore the aviation industry, for many years. Ultimately, there are three reasons why you should care whether something is major or minor: (1) The recordkeeping requirements differ, (2) The persons who can approve the work for return to service differ, and (3) The substantiating data supporting a major action must be approved by the Administrator.
