Self-Induced Fault of a Hydraulic Servo Valve: A Possible Cause for Hidden Malfunction of Aircraft's Systems

by Taehun Seung

Overview

This report describes recent trouble-shooting results in aircraft engineering concerning a self-induced fault mechanism of a hydraulic servo-valve. It presents a possible root cause for past aircraft accidents and as such helps to avoid such malfunction and its fatal consequences in the future.
