Study on Wire and Cable's Fire Resistance Airworthiness for Civil Aircraft

Abstract

The wire and cable as the important material of aircraft, its quality of fire resistance performance influences the safety of aircraft. The requirement of wire and cable's fire resistance performance in airworthiness regulation CCAR-25-R4 is analyzed, and the regulations of domestic and overseas aviation standards and specifications in wire and cable's fire resistance performance are summarized. The airworthiness problem of wire and cable's fire resistance performance is studied, and some suggestions of airworthiness work are given. The cable performance index made by foreign advanced inner-enterprise standards can decrease the airworthiness verification risk for cable used in aircraft, and provide the reference for the selection and usage of wire and cable.
