| Abstract: | In CAAC25, Fuel tank access covers must not failed in service due to impact with failed tire fragments. According to the method of AC25.963-1, FEMA analysis and impact test have done for two types of Fuel tank access cover structures. Compared with the conclusion, achieved more safety Fuel tank access cover structures that was compliant the CAAC25 rules. |
