Commercial Aviation Safety: 7th Edition Chapter 4 Questions (Answered)
1.
What is the ICAO document that describes how accident investigations should be
conducted?
The ICAO document that describes the accident investigation process is called “ICAO Annex
13”, and it provides a framework for how regions should be investigation aviation incidents and
accidents.
2.
Why does aviation use a no-blame approach to accident investigation?
Aviation incorporates a no blame approach to investigations as a way to promote safety
improvement, as people are way more willing to be honest and open about the details of an
accident when they know beforehand that despite any responsibility they might have, It was an
accident and therefore they will not face any legal repercussions (unless negligence or
maliciousness is found). It promotes learning from mistakes and creates a good safety culture
without fear of being honest.
3.
Does no-blame investigation remove responsibility from those connected with an
accident?
No, although the no-blame investigation removes the risk of legal actions being taken against the
person being interviewed in the spirit of having a calm, open, honest dialogue for the overall
improvement of safety, but this does not clear responsibility from those connected to the
accident. Those responsible will still be cited in the accident report for the sake of learning from
their mistakes, and subsequently, pilots who hold responsibility will most likely be directed to
some form of retraining (how much depends on the severity of the accident and how the pilot
performed).
4.
Describe the “party system” and the role of an accredited representative.
The party system in aviation safety involves key stakeholders or accredited representatives from
organizations who have a direct interest in the investigation, providing their expertise and insight
to help under specific aspects of accidents, and ensuring that the investigation is comprehensive
while also meeting their companies interests. The system is there to promote working together,
honesty, and improvement of safety.
5.
List five pieces of evidence that may be gathered at an aircraft accident site.
-
Wreckage and Debris
-
Flight Data and Cockpit Voice Recorder
-
Witness Statements
-
Photographs and Videos
-
Weather Information
6.
What is the purpose of the NTSB Most Wanted List?
The NTSB Most Wanted list serves as a platform where the NTSB can prioritize and emphasize
safety across different modes of transportation, and underlines the importance of being proactive
in safety to protect lives. The list helps raise awareness to the public about current safety issues,
influences policy makers at the federal to local levels, helps measure progress, and fosters
accountability and responsibility.
7.
What power does an SIA have to mandate safety recommendations?
The SIA has authority to make safety recommendations following during or after an aviation
accident investigation. These recommendations are non binding but nonetheless play a pivotal
role in advocating for safety improvements within the industry. Even though it’s voluntary the
comply with their recommendations, it’s very highly encouraged to keep the utmost level of
safety.
8.
Why does accident investigation not always prevent future accidents?
There are a few reasons investigations do not always guarantee the prevention of future
accidents. One of the main reasons is simply human error, as human performance is influenced
by various different factors and one, or even multiple investigations cannot fully eliminate any
errors, but only mitigate, minimize, and spread awareness. Some accidents also simply occur
with unforeseen circumstances or circumstances so specific that they could not have been
properly anticipated, predicted, or recovered from. Some companies also may resist certain
safety recommendations or put them off because they are too costly or take too much time and
resources. Lastly, differences in culture play a big role in this, as a safety recommendation under
one country’s jurisdiction may not be properly enforced, implemented, or understood under
another country’s view.
