The invention relates to an improved method for a ground vibration test (so-called "ground vibration test") on an airplane. In the method according to the invention, the airplane is jacked up essentially undamped ("rigidly") in conventional holding points with lifting devices. For purposes of the ground vibration test, the airplane is then excited to vibrate in a known manner using a plurality of vibration exciters, and the vibrations are acquired with a plurality of measuring transducers, in particular accelerometers. A dynamic vibration model of the airplane theoretically calculated beforehand can here be adjusted. The boundary conditions are removed during or after the ground vibration test, meaning the influence of the lifting device is "mathematically canceled out", so that the determined measured values reflect the so-called "free-free" state of the airplane, as if the airplane had actually been in free flight during the ground vibration tests.
