2016 EWIS Failure Analysis of Commercial Airlines White Paper
Once every couple years, Lectromec reviews the FAA's service difficulty reporting (SDR) system to determine the number of EWIS failures in the American commercial airline fleet. We have reviewed the data, performed a thorough analysis, and placed the conclusions into a white paper. This whitepaper provides details the process and the frequency of EWIS failures.
For those that have seen past assessments, this year’s review has several additional consideration:
- A more in depth and valuation of the sources of EWIS failure and more thorough examination of the causes.
- For the first time, Lectromec looks to determine the annual cost of EWIS failure on commercial airlines.
- Recommended practices to address EWIS failures and improve fleet reliability.
For those that would like additional reference material to support Lectromec’s findings the following articles are recommended:
- List of industry available databases
- Discussion of EWIS components
- Consideration of enhanced zonal analysis procedures for aftermarket modification
- White paper on risk assessment of aged aircraft
- 2014 evaluation of EWIS failure trends
Overall, aviation remains extremely safe and the EWIS failure analysis should not be construed as an industry on the edge of ruin. Rather, we hope that this information will be used to help identify the scope of the problem and help aircraft operators best to focus their attention when it comes to the EWIS within their fleets.
After reading this white paper on commercial airline EWIS failure, we hope that you will consider how the proposed solutions could impact your fleet. The solution has been vetted and is actively being applied to several fleets.
We look forward to your feedback on this white paper.
