Symposium Failure Prevention and Unconventional Failures
Presentation Title The Unusual Case of a Not-so-Obvious Brake Line Failure
Author(s) Erik M. Mueller, Stephen Stein
On-Site Speaker (Planned) Erik M. Mueller
Abstract Scope On October 17, 2013, a privately-owned general aviation airplane was substantially damaged while landing at an airport in Franklin, NC. During the landing, one of the brakes "locked up", causing the airplane to depart the runway. Substantial amounts of brake fluid were discovered on-scene, leading the National Transportation Safety Board investigators to examine the brake lines. During the investigation of the brake lines, what was initially thought to be a simple fatigue fracture turned out to be a complex failure mechanism involving exfoliation, fretting, and galvanic corrosion. This talk will highlight the findings of the accident investigation, as well as the recommendations to prevent this synergistic collection of events from happening in the future.
