Failure Analysis of Engineering Structures: Methodology and Case Histories
Case 49: Failure of a Nose Undercarriage Retraction Jack Support Beam
The nose landing gear on an aircraft malfunctioned during landing roll. After the incident, two fractured studs were found in the retraction jack support beam. Based on visual examination and the results of SEM fractography, investigators concluded that the studs failed by fatigue, a vulnerability because of the way they were mounted. A sketch showing the correct mounting configuration is included in the report.
