MIL-A-8870C, MILITARY SPECIFICATION: AIRPLANE STRENGTH AND RIGIDITY VIBRATION, FLUTTER, AND DIVERGENCE (25 MAR 1993)., This specification contains the general and detail designrequirements and criteria in the design and construction of airplanes to:a. Prevent flutter, divergence, and other dynamic and staticaeroelastic instabilities.b. Control structural vibrations.c. Prevent fatigue failure of the airframe structure or structuralcomponents induced by vibrations, aeroacoustic and other oscillatory loads for the service life of the airplane.d. Prescribe structural dynamic analyses, laboratory and ground tests, and structural dynamic flight tests required to demonstrate compliance with design requirements.e. Apply to airplanes acquired by the Navy for all conditions of flight and surface operations for which the airplanes are required to operate.
