                    Accident investigation

                </a>
            </h2>
        <div id="accordionPanel_37750914" class="c-accordion__container" role="region" aria-labelledby="accordionButton_37750914" style="display: none;">
            <div class="c-accordion__content c-rich-text">
                <p>Travelling by air is extremely safe. There is an average of one fatality for every 287 million passengers carried by UK airlines. This can be compared with a one in 19 million chance of being struck and killed by lightning in the UK or a one in 17,000 chance of being killed in a road accident.</p>
<p>But like all modes of transport very occasionally there may unfortunately be an accident or incident. In the UK these are investigated by the <a href="https://www.gov.uk/government/organisations/air-accidents-investigation-branch">Air Accidents Investigation Branch</a> which is an agency of the Department for Transport.</p>
<p>Their expert investigators will use data from the flight and air traffic control and interviews with those concerned to come to a conclusion on the cause. In complex cases this may take many months. Their reports are then made publicly available.</p>
<p>In some cases those reports may make recommendations to the CAA, aircraft manufacturers or other organisations to look into issues in more detail or make changes.</p>

            <a class="c-accordion__button c-accordion__button--close" href="/" role="button" aria-controls="accordionPanel_37750914">

Guidance

  • The button toggle labels the panel that it opens via application of the aria-labelledby attribute on the panel element
  • The aria-controls attribute on the button toggle defines the relationship between the button and the panel
  • The aria-expanded attribute communicates the state of the accordion to screen reader users
