[2] Loss of control may be the result of mechanical failure, external disturbances, aircraft upset conditions, or inappropriate crew actions or responses.
[2] Loss of control causes aircraft to depart from normal flight and possibly reach altitudes or encounter situations from which it can be difficult or impossible to recover, such as a stall or a spin.
[3] A NASA study focused on identifying causal factors and addressing mitigation challenges related to aircraft loss of control had developed a preliminary list of contributing factors through a process that involved interviews, reviews of accident reports, and team analysis of available data.
Causal factors in the list were segregated into three categories: (1) pilot- or human-induced; (2) environmentally-induced; and (3) systems-induced.
[4] Contributing factors involving inappropriate pilot actions may include:[1] Loss of control has been the cause of many air disasters, some of which are listed below.
