Analysis of 2016 EWIS Failures of the US Commercial Aircraft Fleet … and How to Improve

This 12-page white paper takes a close look at wire system failures in the US commercial airline fleet and proposes methods to improve the wire system reliability.

As Lectromec does once every couple years, we have gone through the FAA service difficulty reporting (SDR) system to determine the number of EWIS failures in the American commercial airline fleet. This white paper details the process and the frequency of EWIS failures.

For those that have seen past assessments, the review this year has several additional areas addressed:

• A more in-depth review of EWIS failure sources and more thorough cause examination.
• Estimated annual cost of EWIS failure on commercial airlines.
• Recommended practices to address EWIS failures and improve aircraft reliability.
