At present, there are still a lot of gaps in the design and development of the cargo baggage net of domestic civil aircraft, so the modification design of the cargo baggage net of the MA60 aircraft is taken as an example and the study of the cargo baggage net of civil aircraft is carried out, which is unfolded from the analysis of users' needs, the design of modification program and the verification of airworthiness compliance accordingly. The design ideas and methods of civil aircraft cargo baggage net are introduced. Finally, the modified cargo baggage net and its components are proved to comply with the requirements of the corresponding airworthiness provisions by means of the relevant airworthiness compliance verification methods, which ensures that the design of civil aircraft cargo baggage net meets not only the users' needs, aircraft performance and technical indexes, but also the airworthiness requirements.
