The Gravity of Error: Forensic Engineering in Flight

Key Insights
#

  • Forensic engineering reveals how microscopic flaws lead to catastrophic failures in aerospace systems.
  • Material interactions under extreme conditions require specialized lubrication and maintenance strategies.
  • Electrical systems in aging vehicles are vulnerable to mechanical damage and insulation degradation.
  • Propeller failures demonstrate the importance of non-destructive testing and design for dynamic tolerance.
  • Failure analysis combines microscopy, spectroscopy, and mechanical testing to prevent future incidents.
