# List of aircraft structural failures

The list of aircraft accidents and incidents caused by structural failures summarizes notable accidents and incidents such as the 1933 United Airlines Chesterton Crash due to a bombing and a 1964 B-52 test that landed after the vertical stabilizer broke off. Loss of structural integrity during flight can be caused by:
* faulty design
* faulty maintenance
* manufacturing flaws
* pilot error
* weather conditions
* sabotage (e.g., an airliner bombing or takeover by a skyjacker).
