Failure Analysis Virtual Lab A failure occurred on the tail section of a commercial aircraft (the failure was video recorded). The transportation safety board has called you in to look at the video and the failed weld in the structural beam weld. Click on the video to see the failure occurring. Click on the beam to analyze the failure. David W. Dickinson Click For Student Data Sheet
