A major modification or repair is one that might appreciably affect weight, balance, structural strength, performance, power plant operation, flight characteristics or other qualities affecting airworthiness; or one that is not done according to accepted practices or elementary operations. All other modifications or repairs are categorised as "minor".
Additional information can be found in Advisory Circular AC21-1(3), including the detailed criteria for the classification of major and minor modification or repair in Appendix A.
