ABSTRACT	The residual strength of three aged FA-200-180 light aircraft was tested in order to confirm the integrity of the aircrafts primary structures. These aircraft have been used in training for about 25 years at the Civil Aviation College. The test results did not show any deterioration in aircraft primary structure compared with the original prototype aircraft in the design limit load range. These aircraft maintained their strength without detrimental or permanent deformation up to the design limit load and, furthermore, without failing for more than three seconds at the ultimate load. Failures of each airframe occurred at 198％, 200％ and 199％ of the design limit load respectively. It was thus demonstrated that the primary structures of these aircraft have retained adequate structural integrity even after 25 years.
