Analysis of the Relationship between CCAR-25 and CCAR-33 Airworthiness

Abstract

The research on the relationship between the terms of airworthiness of transport category aircraft and aeroengine is of great importance to the swift development of airworthiness certification of China. First, utilizing some data of the civil aviation regulations, the integrated data management system can be built. Then, overlapping contents between CCAR-25(China Civil Aviation Regulation-25) and CCAR-33(the regulation about aero engine) are summarized, and the relationship between them are analyzed. At last, the regulations for certain objects about fire-protection system and lubricating oil system are studied. The research results indicate that the relationship between CCAR-25 and CCAR-33 can be divided into five types: citation, selection, supplement, similarity and difference. The hardest thing to define is similarity, which requires a full understanding of the terms, otherwise there is a risk of double certification and missing it. The terms between CCAR-25 and CCAR-33 on fire protection system and oil system have the situation of multiple terms cross-linking. Through the integrated data management system, it can be decomposed into one term corresponding and carried out airworthiness certification.
