Beech Bonanza/Debonair In-flight Structural Failure Events 1962-2007

 

Data from www.ntsb.gov

 

Please note that this list is raw, uninterpreted data only.  All information comes from the NTSB reports.  Because of time constraints no attempt has been made to interpret the data except to categorize each report by factors cited in the NTSB reports.  Further, no attempt has been made to compare these cause factors to similar incidents where the airplane crashed but did not break up in flight, or compare these models of airplanes to other models that have encountered similar conditions.  All comments are quoted directly from the NTSB reports, edited only for length. This record is for training purposes only with the hope patterns emerge that can help pilots of all types of airplanes avoid this, one of the most dreaded causes of aircraft accidents.
