(14) Replacing safety belts. This structure is typically considered to include the fuselage, undercarriage, empennage and wings, and exclude the propulsion system. Areas classified as PSE’s must  be designed (by regulations) with a level of Damage Tolerance that maintains residual strength, fail safe ability, limits damage growth rates and resists a catastrophic failure due to the effect of manufacturing defects or typical damage scenarios. The fuselage is the main structure or body of the aircraft. Biochemistry. It provides space, for cargo, controls, accessories, passengers, and other equipment. Four basic struct ural levels are assigned to proteins: primary, secondary, tertiary and quarternary structures. These Foreign Words And Phrases Are Now Used In English.

This will avoid any misunderstanding, confusion, or customer frustration allowing you to have a smooth transaction. A monocoque fuselage has its skin holding the skeleton structure together while the semi-monocoque has both the skin and the skeleton holding together. "made of several parts". Edge of Part. This rule should be considered the minimum requirement since some regulatory organizations are more restrictive than the others. Additionally, virtually all repairs (other than straight parts replacement) on transport aircraft to Principal Structural Elements or Primary structures are classified as Major Repairs thus necessitating the use of Approved rather than Accepted data to accomplish the repair. The pilot sits in a harness suspended below a hollow fabric wing whose shape is formed by its suspension lines, the pressure of air entering vents in the front of the wing and the aerodynamic forces of the air flowing over the outside. There are several secondary or auxiliary flight control surfaces. chər] (aerospace engineering) The main framework, of an aircraft including fittings and attachments; any structural member whose failure would seriously impair the safety of the missile is a part of the primary structure. ... civil aircraft primary structures interiors aero-engines defence aircraft helicopters space.

Primary Structure Secondary Structure Tertiary Structure Primary Structure: Primary structure includes all the portions of the aircraft, the failure of which during flight or on the ground would cause catastrophic structural collapse and loss of control. ‘The certification of the 737 Composite Horizontal Stabilizer was the first large commercial aircraft primary structure in the world certified for commercial aircraft.’ ‘Primary structure for present transport aircraft is designed, based on average expected operational conditions and average fatigue test results, for 120,000 hrs.’ The airframe is the basic structure of an aircraft and is designed to withstand all aerodynamic forces, as well as the stresses imposed by the weight of the fuel, crew, and payload. For example, the weldability and strength of alloys 2219 and 7039, and the brazeability and strength of X7005, open new avenues for design and manufacture of aircraft structures. Edge of Part. Below we have included the most used aviation acronyms and terms involved in aircraft … primary structure carries flight, ground, or pressurization loads, and whose failure would reduce the aircraft’s structural integrity; secondary structure that, if it was to fail, would affect the operation of the aircraft but not lead to its loss; and For example, EASA regulations (Commission Regulation European Community [EC ] 2042/2003 Annex I Part M require “approved” data for both minor and major  repairs. It provides space, for cargo, controls, accessories, passengers, and other equipment. Primary structures are those structures that bear flight loads and are critical to flight such as the wings, load-bearing portions of the fuselage, the empennage and control surfaces, crew and passenger seats, and doors of pressurized aircraft.
