The results obtained using Non-Destructive Testing on a thirty years old military aircraft having more than 4500 flight hours, almost 80 % of safe life, are described in this paperwok. For this regard, Tear-Down Inspections of some mainly stressed components during in-service life, such as Fuselage Centre Section and Tailplane, were performed by using methods of investigations as eddy current, liquid penetrant, ultrasonic, X-rays and magnetic methods. Some components, such as the Stabilizer Main Spar, the Spacers and the Lower Beam Holes of the Fuselage Centre Section, have required more than one method. The results of investigation have showed the good state of conservation of the aircraft, especially if compared with the results of structures of analogue military aircraft investigated by Australian researchers. The results of this work will be used in the ,Structural Maintenance of Ageing Aircraft' BRITE-EURAM program, aimed at getting information about phenomena that involve the structures of aircrafts that have reached the end of the project life with the purpose of extending the life itself, achieving a high level of safety.
