Basic Airframe Repair
Subcourse Number AL0992 EDITION A US Army Aviation Logistics School Fort Eustis, Virginia 23604-5439 4 Credit Hours Edition Date: September 1994 SUBCOURSE OVERVIEW This subcourse is designed to provide you with a general familiarization of the airframe of today's aircraft and repair procedures. You will study the design and construction of aircraft parts and assemblies, metals used in the construction, and the metal qualities and stresses involved. You will also study procedures involved in the repair of damages to the aircraft skin and structure and the type of hardware required. Early aviation's aircraft made of wood and fabric, reinforced with metal, were strong enough to withstand the vibrations and torsion stresses met at slow speed. However, with the need for higher speeds, greater payloads, and more powerful engines, wood became unsatisfactory. Manufacturers and designers realized that structural parts made with metal must replace the wood and fabric. So they developed light, strong metal alloys. To these they applied structural forming and reinforcing methods to reduce weight and to gain the strength required for increased performance. Making repairs involved selecting the right metal for structural strength and streamlining, choosing the type of rivet to use, and determining the type of patch that will meet structural requirements. Also important is determining how much weight can be added, within safe limits, and choosing the method of structural forming and reinforcement to use. You will find this text divided into two chapters which discuss airframe parts, metals, processes, hardware and damage repair. However, the discussion here is not a substitute for the technical manual (TM) applicable to a specific aircraft or a particular repair technique. The information given here is designed to give you a general background in basic airframe repair. This subcourse is to be completed on a self-study basis. You will grade your lessons as you complete them using the lesson answer keys which are enclosed. If you have answered any question incorrectly, study the question reference shown on the answer key and evaluate all possible solutions. There are no prerequisites for this subcourse. This subcourse reflects the doctrine which was current at the time it was prepared. In your own work situation, always refer to the latest publications. Unless otherwise stated, the masculine gender of singular pronouns is used to refer to both men and women. TERMINAL LEARNING OBJECTIVE ACTION: You will demonstrate a knowledge of the basic fundamentals of airframe repair including airframe parts, metals, metal processing, hardware, and required procedures. CONDITIONS: You will use the material in this subcourse. STANDARD: You must correctly answer a minimum of 70 percent of the questions on the subcourse examination to pass this subcourse.
