SCOPE
l.1 Scope.
This speclficatton contains the general and detail design
requirements and criteria in the design and construction of airplanes to:
a. Prevent flutter, divergence, and other dynamic and static
aeroelastlc instabllittes.
b. Control structural vibrations.
c. Prevent fatigue failure of the airframe structure or structural
components induced by vibrations, aeroacoustic and other oscillatory
loads for the service llfe 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 toalrplanes acquired by the Navy for all conditions of flight
and surface operations for which the airplanes are required to operate.
