Aircraft Structural Accidents
What We Can Learn From
Them
WHO SHOULD PARTICIPATE
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.
KEY TOPICS
- 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.
HOW YOU WILL BENEFIT FROM THIS COURSE
- 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.
