Historical (view previous versions of standard)
This specification covers airworthiness requirements for the design of a powered or non-powered fixed wing light sport aircraft, a ?glider.? Stability shall be shown by a tendency for the glider to return toward steady flight after: (1) a ?push? from steady flight that results in a speed increase, followed by a non-abrupt release of the pitch control; and (2) a ?pull? from steady flight that results in a speed decrease, followed by a non-abrupt release of the pitch control. Strength requirements are specified in terms of limit loads (the maximum loads to be expected in service) and ultimate loads (limit loads multiplied by prescribed factors of safety). The suitability of each structural design detail and part having an important bearing on safety shall be established by test. Each combination of engine, exhaust, cooling and fuel system on a powered glider must be compatible with the glider, and function in a safe and satisfactory manner within the operational limits of the glider and powerplant. Each aircraft shall include Aircraft Operating Instructions (AOI).
This abstract is a brief summary of the referenced standard.

1.3 A glider for the purposes of this specification is defined as a heavier than air aircraft that remains airborne through the dynamic reaction of the air with a fixed wing and in which the ability to remain aloft in free flight does not depend on the propulsion from a power plant. A powered glider is defined for the purposes of this specification as a glider equipped with a power plant in which the flight characteristics are those of a glider when the power plant is not in operation.
