Aircraft Maintenance

Posted by Aircraft Maintenance on April 9th, 2021

Aircraft maintenance is the procedure performed by a licensed professional to check and identify any damage or malfunction of machining parts, electrical and other components of the aircraft product. Aircraft are frequently exposed to extreme environments that may damage or destroy them such as collisions, turboprops, high levels of humidity, heat, solid fuel, low pressure oil, corrosion, vibration, and adverse weather conditions. All these factors can impact the physical structure of the aircraft and its electrical systems. Regular maintenance, on the other hand, will help prolong the life span of the aircraft products and make sure that they are in perfect working condition. A licensed mechanic is an asset for an airframe and other aircraft companies to keep the aircraft running efficiently.

An experienced mechanic will have the skill to identify the causes of premature failure, defective parts, root causes of mechanical problems, aircraft weight, environmental conditions, and fuel system deficiencies. Most small cracks and other structural anomalies are easy to repair but when it comes to the larger crevices of the aircraft, extensive cracking may have already started. The effects of aging aircraft are another big concern. Cracks and small cracks gradually widen and spread across an aircraft, which weakens its integrity and increases the risk of catastrophic failure.

A company's quality of cessna caravan inspections programs, equipment, material, and training directly affects the ability to prevent failures in critical areas of the aircraft structure. This is particularly relevant for the area of structural fatigue. There are three key areas to address in any aging aircraft maintenance programs. First, an airframe must have the right thickness. If the airframe is too thin, there is a high chance of stress corrosion cracking, fatigue cracks, and large fatigue cracks. In order to avoid these devastating events, manufacturers require an appropriate amount of thickness.

Next, service experience plays a vital role in the prevention of corrosion fatigue cracks. Proper maintenance programs include a regular assessment of the condition of the coating, the thickness, and tensile strength. The service experience includes both mechanical and non-mechanical methods of testing. These include arbor loads, tensile strengths, creep resistance, and compressive strength. An important aspect of aircraft service programs is the identification and determination of the effect of changing temperatures on the surface/resistance to impact.

Finally, the strength and hardness of the composite material used in the aircraft structure plays a crucial role in preventing fatigue cracks. Composite materials include fiberglass, carbon fiber, laminate, and composite resin. All of these materials have different effects on the surface, including compressive and tensile strength, which can affect fatigue cracks. Composite material manufacturers must first develop a fatigue crack specification that is then followed by quality control measures, to ensure that composite structures are strong enough to withstand the aircraft weight.

In addition to fatigue cracks, it is important to prevent small cracks from developing into larger structural anomalies. Unfortunately, this often proves difficult to do, as small cracks tend to dissipate rather quickly. Unfortunately, too many small cracks can weaken an airplane's integrity over time, leading to increased energy consumption due to root erosion and increased structural weight. Residual strength, on the other hand, can increase with time. The purpose of residual strength is to reduce the energy losses due to root erosion, increased structural weight, and increased structural stability.

Proper aircraft maintenance programs also involve scheduling maintenance on an aircraft according to its operational load. This scheduling will involve considering potential loads according to the manufacturer's specifications, taking into account factors such as aircraft weight, load factors, and fuel use. A high-wing aircraft, for instance, will have a much greater nose-to-tail load, while a small single-engine airplane will have a much smaller load. Additionally, the aircraft must be scheduled for maintenance according to their flight characteristics. For instance, low-wing aircraft are designed to fly at slow speeds, whereas high-wing aircraft are designed to fly at higher speeds.

Aircraft maintenance is only one of the many factors that must be considered in an aircraft's maintenance program. When scheduling maintenance, it is also important to consider serviceability, manufacturing standards, and other environmental considerations. While a good maintenance program is essential to maintaining an aircraft's operational capability, sometimes it is not enough. When this happens, it is vital to schedule additional maintenance to keep the aircraft performing at its maximum efficiency.
