Abstract
The aim of the current study is to analyze the failure reasons of towing accidents happened in 2004 and 2005. We found joint gaps were between aircraft-towbar-tractor which might been the possible cause of failure. Fracture analysis techniques were performed to the fracture of down drag, shear pins and etc. The dynamic simulation was performed to analyze the impact of joint gaps on the load of down drag. The result confirmed that down drag and shear pins were overload fracture caused by great impulse towing load caused by joint gaps between aircraft-towbar-tractor under uncommon situations, and the structure of towbar should to be improved as the utilizes of shear pins to guarantee the security of towing system was not enough.
