Aviation Basics – Aircraft Maintenance Fundamentals

Microfilm, Microfiche, and Digital Images in Aircraft Maintenance

Aircraft drawings and technical documents are essential for aircraft maintenance, inspection, and repair. These documents have traditionally been stored and accessed using methods such as microfilm and microfiche. With advances in technology, digital images and electronic storage have become important tools for managing and sharing aircraft technical information. Understanding these methods helps aviation maintenance technicians … Read more

DC Motor Construction and Types

DC Motor Construction The major parts of a practical DC motor are the armature assembly, the field assembly, the brush assembly, and the end frame. [Figure 1] Armature Assembly The armature assembly contains a laminated soft-iron core, coils, and a commutator, all mounted on a rotatable steel shaft. The armature core is formed from a … Read more

Hole Repair and Aircraft Control Cable Hardware

Aircraft fastener holes may require repair after corrosion removal, fastener replacement, or minor damage. This section explains approved hole repair methods, the use of Acres fastener sleeves, and the basic construction and hardware of aircraft control cable and push-pull linkage systems. Many of the blind fasteners are manufactured in oversized diameters to accommodate slightly enlarged … Read more

Precision Layout and Measuring Tools

Layout and measuring devices are precision tools. They are carefully machined, accurately marked and, in many cases, are made up of very delicate parts. When using these tools, be careful not to drop, bend, or scratch them. The finished product is no more accurate than the measurements or the layout; therefore, it is very important … Read more

DC Generators: Theory, Construction, and Types

Direct current (DC) generators convert mechanical energy into electrical energy through electromagnetic induction. Although modern aircraft primarily use alternators, understanding DC generator operation remains important because many aircraft systems and electrical principles are based on generator fundamentals. This article explains the theory of DC voltage generation, the function of commutators and armatures, the effects of … Read more

Aircraft Safety Wiring and Fastener Safetying

Aircraft hardware and fasteners are subjected to constant vibration, aerodynamic loads, and operational stresses during flight. To prevent nuts, bolts, screws, turnbuckles, and other components from loosening, various safetying methods are used throughout the aircraft. Proper installation and inspection of safetying devices are essential to maintain structural integrity, system reliability, and flight safety. Safetying Methods … Read more

What Are Human Factors in Aviation Maintenance?

The term human factors has grown increasingly popular as the commercial aviation industry realize that human error, rather than mechanical failure, underlies most aviation accidents and incidents. Human factors science or technologies are multidisciplinary fields incorporating contributions from psychology, engineering, industrial design, statistics, operations research, and anthropometry. It is a term that covers the science … Read more

Aviation Human Factors and Error Prevention

Human factors are a critical element in aviation safety and maintenance. While aircraft systems and technologies are highly advanced, human performance continues to play a major role in preventing accidents and ensuring safe operations. Understanding how people interact with aircraft systems, tools, and their working environment is essential for reducing errors and improving reliability. Human … Read more

Aircraft Materials, Hardware and Processes

Aircraft are constructed from a wide range of materials and assembled with specialized hardware designed to meet demanding strength, weight, and durability requirements. Aviation maintenance technicians must understand the properties of these materials and the functions of aircraft hardware in order to inspect, repair, and maintain aircraft safely and effectively. Metallic materials used in aircraft … Read more

Aircraft Cleaning and Corrosion Control

Cleaning and corrosion control are essential parts of aircraft maintenance because corrosion can weaken structures, damage components, and reduce the service life of an aircraft. Since aircraft are exposed to moisture, chemicals, salt, exhaust deposits, and other environmental contaminants, maintenance personnel must understand how corrosion develops and how it can be controlled before serious damage … Read more
