ABSTRACT	Full-scale ground vibration tests were carried out on an aged FA-200-180 aircraft by using a dynamic displacement measurement system. The test aircraft has been used in training for about 12,000 hours at the Civil Aviation College. The transfer function method with dual correlated random excitation was adopted in this test. The test results showed that several vibration modes were separated and that the resulting natural frequencies and nodal lines were similar to those of the original prototype aircraft. The vibration characteristics did not show any appreciable diffe
