When the equipment in an aircraft is changed, such as the installation of a new radar system or ground proximity warning system, or the removal of a radio or seat, the weight and balance of an aircraft changes. An alteration performed on an aircraft, such as a cargo door being installed or a reinforcing plate … Read more
Aircraft structures include several areas that are particularly susceptible to corrosion due to their design, environment, and operational exposure. These corrosion-prone zones require more frequent cleaning, inspection, and protective treatment compared to less exposed areas. While the following sections highlight common problem areas found across most aircraft, maintenance personnel should always refer to the applicable … Read more
Scales Weighing GA aircraft, helicopters, turboprops, corporate jets, UAV/UAS, or transport category airliners can be accomplished in two ways: top of jack load cells and platform scales. Equipment selection is dependent on the operator’s needs and or equipment currently on hand, as well as the airframe manufacturer’s recommendations. Top of jack load cells, as the … Read more
There are many forms of corrosion. The form of corrosion depends on the metal involved, its size and shape, its specific function, atmospheric conditions, and the corrosion producing agents present. Those described in this post are the more common forms found on airframe structures. Surface Corrosion General surface corrosion (also referred to as uniform etch … Read more
As a general rule, only rated pilots and qualified airframe and powerplant (A&P) technicians are authorized to start, run up, and taxi aircraft. All taxiing operations are performed in accordance with applicable local regulations. Table 1 contains the standard taxi light signals used by control towers to control and expedite the taxiing of aircraft. The … Read more
There are two general classifications of corrosion that cover most of the specific forms: direct chemical attack and electrochemical attack. In both types of corrosion, the metal is converted into a metallic compound, such as an oxide, hydroxide, or sulfate. The corrosion process involves two simultaneous changes: the metal that is attacked or oxidized suffers … Read more
Corrosion in aircraft structures is influenced by a wide range of environmental, material, and operational factors. Understanding these factors is essential for aircraft maintenance technicians, as corrosion can develop at different rates and in various forms depending on conditions. The following sections outline the key factors that affect corrosion in aircraft and how they influence … Read more
Movement of large aircraft about the airport, flight line, and hangar is usually accomplished by towing with a tow tractor (sometimes called a “tug”). [Figure 1] In the case of small aircraft, some moving is accomplished by hand pushing on the correct areas of the aircraft. Aircraft may also be taxied about the flight line … Read more
Preparation of Aircraft Aircraft are to be tied down after each flight to prevent damage from sudden storms. The direction that aircraft are to be parked and tied down is determined by prevailing or forecast wind direction. Aircraft are to be headed into the wind, depending on the locations of the parking area’s fixed tie-down … Read more
Due to a large number of maintenance-related aviation accidents and incidents in the late 1980s and early 1990s, Transport Canada identified twelve human factors that can degrade a technician’s ability to perform safely and effectively. These factors, known as the “Dirty Dozen,” are widely used in the aviation industry as a simple way to understand … Read more
