The importance of cleanliness in aircraft

Although they are made to last, aircraft do have a lifespan. A plane's "in-service" life expectancy is 20 years. Cleaning your aircraft is probably one of the last things on your mind after a lengthy flight. The performance and long-term health of your aircraft, however, can be greatly impacted by the accumulation of dirt, insects, and other debris. To accomplish this, periodic maintenance is necessary for these pricey and powerful machinery. Without routine maintenance, damage that reduces the lifespan of an aircraft may emerge. 

Here are some reasons why you shouldn't skip the cleanliness in aircraft after a flight and how crucial airplane maintenance is by reading the following material.

The Importance of Cleanliness in Aircraft

1. Chemical contamination-related corrosion

To ensure safety and effectiveness, cleanliness in aircraft is essential. An aircraft accumulates an incredible quantity of pollution during routine daily operations. Even while a plane may appear spotless to the untrained eye, every flight will acquire a thin layer of chemical pollutants that might lead to corrosion if left on the surface.

Metals slowly deteriorate through corrosion due to electrochemical activity. Throughout the world, aircraft operate in climatic regions with a wide range of conditions, some of which are particularly favorable to the development of corrosion. Sea salt and salt-laden sand are two of the most frequent and damaging contaminants an airplane can encounter worldwide.

Exhaust gasses from aircraft engines, which are then deposited on the aircraft's surface, also produce pollutants. Due to the nature of these by-products, they will react with substances in the air to create corrosive compounds.

Detecting any issues, such as leaks that may develop on the underside surrounding hydraulic, water, and overflow ports and drains, will be aided by maintaining cleanliness in the aircraft. Also, it will give prospective passengers flying confidence by demonstrating how well-maintained the aircraft is.

2. Aircraft equipment protection

Regular airplane cleaning keeps vital components, such as antennas located beneath the aircraft, protected from harm. These components may become covered in dirt and oil residue from aircraft engine exhaust. This results in risky flying situations since the antennas cannot transmit signals properly. Cleaning down the equipment after each trip is a simple and convenient way to maintain its performance.

3. Safety for passengers and pilots

When a plane is in use, it is crucial to maintain the cleanliness of the aircraft, ensuring safety. As an illustration, a buildup of dirt and debris on the windshield can reduce visibility, making it risky for pilots to fly these aircraft. Moreover, dirty windshields can make it much more difficult for pilots to see distant vehicles. Aircraft windshields should be kept as spotless as possible to reduce the likelihood of these safety risks and ensure safe flying.

After a flight, staying a little while to give your aircraft some much-needed care is well worth it. "An ounce of prevention is worth a pound of cure," as the proverb goes. Maintaining consistent post-flight cleanings can help you preserve your investment for years.

4. Protective coatings and films

More lightweight metals and unusual materials are being used in the manufacture of aircraft as technology advances. When these kinds of materials are combined, fast deterioration might result. Certain aviation materials are frequently coated with protective films and coatings to aid in preventing this. Cleanliness in aircraft and a longer life span for airplanes can be achieved by lowering the risk of deterioration.

The Procedures for Airline Aircraft Cleaning

1. Aircraft exterior cleaning

Let's begin with the aircraft's exterior. An airplane's fuselage has to be cleaned. Cleaning up dirt and debris also improves the aerodynamics and effective operation of the plane. Also, it aids in highlighting any skin damage. For this reason, many airlines schedule exterior cleaning right before maintenance inspections.

Cleaning an aircraft is trickier than it seems. After covering the sensors and inlets, a sizable portion of the fuselage can be accessed and cleaned. It takes a lot of time.

Aircraft can be dry-washed or washed with water and detergent. High-pressure water jets and specialized detergents are typically used for wet washing. Detergent advancements are credited with enabling several airlines to reduce cleaning frequency.

Some airlines now employ the more recent technology of dry washing. Applying cleaning products to the surface and removing them using mops or wipes are involved. This can be done anywhere and consumes much less water, which is fantastic for the environment and money.

2. Cleaning the engines

Another way to keep the aircraft clean is by cleaning the engines. The engines will be cleaned differently because they are obviously very different from the rest of the exterior. Motors are plugged in or covered during routine wet washing to prevent damage. Again, this is not a process that is performed frequently, and it usually goes along with extensive maintenance inspections.

Fresh water is cycled through the turbine to clean the interior of the engines. Cleaning isn't finished until the water exiting the machine's back is crystal clear. You can employ solvents to dissolve any particle accumulations.

3. Daily cleaning of the cabin

The interior of the airplane cabin needs to be cleaned after every flight, as opposed to the exterior fuselage and routine cleaning. Of course, this varies between airlines and flight kinds. With a low-cost airline after a brief journey, the aircraft might only clear out the evident trash and grime in between flights. After the day's service, more extensive cleaning may subsequently be done. A widebody will require a significantly deeper clean before being returned to service after a lengthy voyage. Customers' expectations are also a factor in this, in addition to cleanliness in aircraft.

Light cleaning will entail gathering trash, switching out linens, and wiping surfaces. Vacuuming, checking the condition of the seat covers, and more thorough disinfecting are all part of a more thorough daily or widebody clean.

Aircraft will also undergo routine deep cleanings in addition to cleaning during maintenance. This will again differ between carriers and types of aircraft. Deep cleaning is reportedly done on Singapore Airlines once a month and on British Airways once every 500 flight hours. All surfaces, materials, and spaces like air vents will be thoroughly cleaned.

Understand the advantages of aircraft cleaning

Keeping an airplane clean while undergoing maintenance has numerous advantages. Cleaning makes it easier to find and quickly fix issues with aircraft, such as leaks near hydraulics on the underbelly, overflow, or water drains and holes. As a result, airplanes are always kept in a safe operational state. In cleaning an aircraft, aircraft maintenance specialists can look for these issues. Also, having cleaning done increases passengers' trust in the upkeep of their aircraft.
