description abstract	A flight investigation has been made to check the results of a theoretical analysis of longitudinal stability of an airplane with free controls. Tests were made of a Fairchild XR2K-1 airplane on which the weight moment and the aerodynamic balance of the elevator were varied to bring it into a condition where unstable short-period oscillations were encountered. The amounts of aerodynamic balance and weight moment required for instability were found to be greater than the amounts predicted by the theory. Time histories of the oscillations are included to show the nature of the instability.
