In an ultra-safe industry, the loss of control in-flight (LOC-I) type of accidents may be rare but on average it accounts for one quarter of all fatalities in scheduled commercial air transport.
One way to identify safety issues is through the systematic analysis of occurrence data, in particular by accident categories (e.g. Loss of control in-flight, Mid-Air Collision, etc) or by aviation domain (Commercial Air Transport, Business Aviation, General Aviation, etc).
LOC-I can result from a range of interferences including engine failures, icing, or stalls. It is one of the most complex accident categories, involving numerous contributing factors that act individually or, more often, in combination.
