A 737-300/400/500MAINTENANCE MANUAL STRUCTURES - DESCRIPTION AND OPERATION ______________________________________ 1. General_______ A. The structure of the airplane (Fig. 1) is designed to provide maximum strength with minimum weight. This object has been achieved by designing alternate load paths into the structure, so that a failure of one segment cannot endanger the airplane, and also by the use of appropriately selected materials. The materials most commonly used thoughout the structure are aluminum, steel, and magnesium alloys. Of these, the most extensively used are certain aluminum alloys selected according to the particular type of load they are best suited to withstand. B. Aluminum and fiberglass honeycomb core material is used extensively on secondary areas of structures and many of the flight surfaces. C. Maintanance practices concerning blowout doors and panels are covered in applicable chapters on structures. See Fig. 3 for a comprehensive illustration of blowout doors and panels on the airplane. 2. Fuselage________ A. The fuselage is a semimonocoque structure with the skin reinforced by circumferential frames and longitudinal stringers. It is composed of four sections: body sections 41, 43, 46, and 48, of which the forward three together extend from body station 178 to body station 1016 and contain all the passenger, crew, and cargo accommodations. The fourth section of the fuselage is at the aft end and provides support for the empennage. www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：737-300 400 500 AMM 飞机维护手册 结构 STRUCTURES
