The plain washers also may be used as a shim under a nut to compensate for a bolt that is slightly long.

Why do we wash airplanes?

The primary purpose of washing is to reduce the amount of corrosion occurring in the airframe. Washing is the first step in the aircraft’s CPCP (Corrosion Prevention & Control Plan).

Which are special washers used where a bolt is installed at an angle to a surface?

Shakeproof lockwashers are round washers designed with tabs or lips that are bent upward across the sides of a hex nut or bolt to lock the nut in place. They are special washers used where a bolt is installed at an angle to a surface, or where perfect alignment with a surface is required.

How do they wash airplanes?

The exterior of the plane is either cleaned by soap and a powerful jet of water, or by drywashing. The interior can either undergo a ‘clean sweep’ or a more rigorous cleaning process, called a ‘deep clean’. The cabin floor is shampooed and vacuum cleaned.

What is hangar maintenance?

A maintenance hangar is different than that of a line or storage hangar in that its main purpose is to provide adequate space to conduct major repairs on aircraft. This is where maintenance stands, scaffolding, tools, test stands and other equipment are housed.

What should be done when washing an aircraft?

The washing of aircraft should be performed in the shade whenever possible, as cleaning compounds tend to streak the surface if applied to hot metal or are permitted to dry on the area. Install covers over all openings where water or cleaners might enter and cause damage.

Why is cleaning and disinfection on aircraft important?

“Cleaning and disinfection on aircraft require special attention, as it is necessary to use agents that are not corrosive or otherwise detrimental to aircraft components,” WHO explains in its book. “For this reason, not all effective cleaning disinfecting agents can be used in the aircraft cabin”, for example.

What is the who’s guide to airplane cleaning?

In fact, the subject of aircraft cleaning is so complex that the World Health Organisation (WHO) has published a magnum opus on the subject, entitled ‘A Guide to Hygiene and Sanitation in Aviation’.

How do maintenance engineers deal with the challenge of cleaning aircraft?

By choosing specialised parts-cleaning equipment and combining it with cleaning agents that meet aviation approved chemistries, maintenance engineers can ease the challenge of cleaning, even if, as with the Boeing 737, there’s 367,000 parts to get through.
