Loss of Control In-flight (LOC-I) remains one of the most significant contributors to fatal accidents worldwide. LOC-I refers to accidents in which the flight crew was unable to maintain control of the aircraft in flight, resulting in an unrecoverable deviation from the intended flight path.
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. Reducing this accident category, through understanding of causes and possible intervention strategies, is an industry priority.
Environmental Factors Affecting LOC-I
Download the LOC-I Accident Analysis Report (pdf) to get an evaluation of the risk factors from recent LOC-I accidents and information designed to aid industry in the implementation of mitigation strategies.
This interactive PDF report is organized in a way to provide dynamic environment data from 64 LOC-I accidents that occurred over the last 10 years, spanning from 2009 through 2018. This report contains embedded interactive Excel graphs and is written to support a user-friendly methodology to analyze and visualize LOC-I accident data and to identify patterns, trends, comparisons between data selections.
For maximum functionality, please download and save a copy of the report, before opening with Adobe Acrobat.
The embedded MsExcel graphs are available for users with Microsoft Office versions 2013, 2016 and Office 365. Please close any opened excel files after viewing in order to maintain optimum performance.

Numerous fatalities resulted from Loss of Control In-Flight (LOC-I) accidents in recent years and the industry sees a need to take action. As an accident category, LOC-I is very broad and there are many different sequences that can lead up to an accident. This makes it difficult to produce a single, effective guidance document to help prevent LOC-I.
