## The analysis of causal and contributing factors leading to loss of control in - flight

### Ida Maria Gwóźdź

#### Abstract

Loss of Control In-Flight (LOC) is one of the largest contributors to aircraft accidents worldwide. This is a very complex phenomenon, resulting from many causal and contributing factors. The aim of this Engineering Thesis is to present and evaluate those factors. The investigation is based on the analysis of Loss of Control accidents, which happened between years 1978 and 2018. First of all, the definition of Loss of Control In-Flight is stated, main charasteristics and primary reasons of this phenomenon are evaluated. Chapter 2 presents a detailed analysis of loss of control events. Firstly, causal and contributing factors are defined and then they are grouped into three main sets: unwanted aircraft conditions, external hazards and vehicle upset. Based on that, the accidents in the data set are categorised. Then, the contribution of each group of factors to LOC events occurence is shown and most frequent reasons are evaluated. Next chapter presents sequencing of factors proceeding loss of control events in the data set. The worst sequences and precursors are defined and described. In order to evaluate the sequencing of factors in detail, Chapter 4 presents the description of two accidents involving Loss of Control In-Flight. The first one is the catastrophe of Air France Flight 447 and the second one is the accident of TransAsia Airways Flight 235. Finally, the ways of prevention and future potential risks are considered.
