scope:

General.-

This specification contains general requirements, which, in combination with other applicable specifications, define the structural design, analysis, test , and data requirements for fixed wing piloted airplanes, ineluding but not limited to:

(a)The strength and rigidity of the structure of the airplane including supporting and carry-through structures for fixed equipment and useful load items.

(b) The strength and rigidity of control systems for operation of lateral, longitudinal, and directional control surfaces; dive or speed brakes; high lift devices; tabs; stabilizers; spoilers; certain other mechanisms; and their respective carry-through structures.

(c) The shock-absorption characteristics and strength of landinggear and beaching-gear units and the strength and rigidity of their control systems and of their carry-through structures. These requirements include wheels, tires, and brakês of Navy airplanes, but do not include tires , tubes, wheels, and brakes of U. S. A i r Force airplanes.

(d) The strength of structures integral with the airplane provided for transmitting catapulting forces to the airplanes and f or engaging arresting gear, barrier actuators, barrier cables, and barricades. The strength of anchor-line clamps, and the airplane strength f o r hoisting, jzcking, towing, mooring, and other ground, deck, or water-handling conditions.

(f) Flutter prevention and vibration characteristics.

(g) Determhation of specia.1 weapons effects.

(h) Structural design, analysis, and test data.

(i) Laboratory and flight tests performed to obtain information regarding strength rigidity and loads.

(j) Definitions.

Modifications and amD1ifications.- This specification will be modified and amplified in contracts for piloted airplanes by type, detail, and design data specifications and addenda thereto.

intended Use:

The requirements of this specification shall be used for the structural design and structural substantiation of airplanes..
