Abstract

The invention belongs to the technical field of aviation, and relates to a troubleshooting analysis method of an aircraft system. The method comprises the following steps: step 1, from the perspective of maintenance, based on an engineering fault mode influence analysis result, forming a fault mode influence analysis integration table based on supportability analysis; 2, determining a troubleshooting demand according to a fault mode influence analysis integration table based on supportability analysis, and forming a fault fuzzy group list; 3, determining a troubleshooting sequence of each replaceable unit in the fault fuzzy group list; and 4, formulating a troubleshooting program according to the determined troubleshooting sequence.

Description

technical field [0001] The invention belongs to the technical field of aviation and relates to a troubleshooting analysis method for an aircraft system. Background technique [0002] The main purpose of Troubleshooting Analysis (TSA) is to determine the troubleshooting sequence and procedures according to the fault phenomenon, so as to obtain the corrective maintenance work items, as the input of Maintenance Task Analysis (MTA), and then analyze the process and required support resources , and ultimately provide technical support for the compilation of troubleshooting manuals and safeguard resource catalogs. [0003] At present, there are no normative standards for troubleshooting analysis methods at home and abroad, and the compilation of troubleshooting manuals in model development depends entirely on the experience of designers. To solve the troubleshooting problem, it is urgent to establish a standardized troubleshooting analysis method. Contents of the invention [...
