Aircraft Structural Accidents
What We Can Learn From Them



There are no prerequisites for this course, and it will involve very few mathematical calculations. Design engineers, scientists, college professors, structural engineers, maintenance personnel, airline logistics and liaison engineers, and materials science personnel will benefit. This course is also suited to engineers, technicians, and managers in airlines, aircraft modification centers, aircraft and component manufactures, and defense installations, as well as airworthiness agencies like the FAA.


  • What can we learn from accident investigation reports?
  • Commercial jet structural accidents: Airbus, Boeing, and Douglas aircraft accident investigation reports.
  • Assessments of accidents by the National Transportation Safety Board.
  • Failure analysis reports from Norway, Australia, Canada, England, and U.S.


  • Gain a thorough understanding of the frequent causes of structural accidents fatigue, stress corrosion, corrosion fatigue, wear, etc., and the design features or maintenance repair events that lead to them.
  • Learn how to use metallurgic laboratory reports to make simple calculations related to the accident, like crack growth rates in the structure, stress corrosion thresholds, residual strengths, and critical crack sizes.


Day 1

  • The role of aircraft structural accident reports in fostering aviation safety
  • Fundamental failure mode contribution to a typical aerospace structural deficiency
