- Abstract
Subpart E of Chinese Civil Avialion Regulation - Continued Airworthiness and Safety Improvement for Transport Category Airplanes (CCAR-26), requires for the evaluation of airplanes structures after repairs and modifications. This study analyzes the requirements of CCAR 26.41, CCAR 26.43, CCAR 26.45, CCAR 26.47, and CCAR 26.49. The differences between CCAR-26 subpart E and 14 CFR Part 26 Subpart E are studied. The related technical requirements and means of compliance of Subpart E are summarized. The findings can provide reference for the certification of transport airplanes.
