Abstract

Laboratory investigation showed that damages to the tail strut assembly of a helicopter were caused instantaneously under high impact load. There were no signatures of progressive failure such as fatigue in any of the components of the assembly. Also, no metallurgical abnormalities in the material of construction were responsible for the failure. Analysis suggests that the tail strut assembly suffered a high intensity impact load either because of non-absorbance of shock or hard landing. A detailed analysis of the failure is presented in this report.
