What are the procedures ways to be prevented corrosion in maintaining the aircraft airworthy?

Preventing Aircraft Corrosion

1. The most important means for preventing corrosion is to keep aircraft free of moisture.
2. A thorough rinsing and cleaning of aircraft will remove salt and other corrosive agents.
3. Chipped or delaminating paint needs to be properly striped or sanded and re-painted.

What should be done to a control cable having some internal corrosion and why?

Replace cables that have internal corrosion. Remove light external corrosion with a nonwoven abrasive pad lightly soaked in oil or, alternatively, a steel wire brush. When corrosion products have been removed, recoat the cable with preservative.

What are the the things that needs to be checked when performing an on aircraft inspection?

Engine and Nacelle

• Engine — signs of leaking oil, fuel or hydraulic fluids, cylinder compression and debris on screens and sump drain plugs.
• Dampeners — deterioration or damage.
• Cowling — cracks or defects.
• Exhaust — proper attachment and cracks or defects.
• Studs and nuts — loose or missing.

How is intergranular corrosion removed How is it inspected?

Intergranular corrosion is inspected by using the NDT method, such as ultrasonic inspections or radiography inspection. It is removed by replacing the part.

What is the best way to prevent corrosion?

5 Different Types of Corrosion Prevention Methods

1. BARRIER COATINGS. One of the easiest and cheapest ways to prevent corrosion is to use barrier coatings like paint, plastic, or powder.
2. HOT-DIP GALVANIZATION.
3. ALLOYED STEEL (STAINLESS)
4. CATHODIC PROTECTION.
5. EONCOAT – A NEW WAY TO PROTECT ASSETS FROM CORROSION.

What are the 3 keys to corrosion prevention?

Key Points Three things are necessary for corrosion to occur: an electrolyte, an exposed metal surface, and an electron acceptor. Corrosion can be prevented by removing one of these conditions. Coating a metal surface with paint or enamel provides a barrier between the metal and the moisture in the environment.

What are the procedures as indicated for corrosion protection?

5 Different Types of Corrosion Prevention Methods

• BARRIER COATINGS. One of the easiest and cheapest ways to prevent corrosion is to use barrier coatings like paint, plastic, or powder.
• HOT-DIP GALVANIZATION.
• ALLOYED STEEL (STAINLESS)
• CATHODIC PROTECTION.
• EONCOAT – A NEW WAY TO PROTECT ASSETS FROM CORROSION.

How are cables inspected for broken wires?

The easiest way to check for exposed strands of broken wire on a cable is to have one person move the cable through its length of travel while another person holds a cotton cloth gently around the wire looking for places that the cable snags the wire.

What are 3 things that need to be checked when performing key and key screw inspection?

Key and Key Screw Inspection As mentioned, there should be no movement between the wheel and the keys. The bolts should be checked for security, and the area around the keys should be inspected for cracks. There is also a limitation on how worn the keys can be since too much wear allows excessive movement.

What inspections are required to maintain an airworthy aircraft?

Technical Information

• Annual Inspection (FAR 91.409) Most general aviation aircraft require an annual inspection.
• 100-Hour Inspection (FAR 91.409)
• Progressive Inspections (FAR 91.409)
• Items Checked During Inspections (FAR 43)
• Altimeter (FAR 91.411)
• Transponders (FAR 91.413)
• Emergency Locater Transmitter (FAR 91.207)

What type of inspection is usually required to detect intergranular corrosion?

Ultrasonic inspection can detect corrosion damage on some surfaces. It is commonly used to detect exfoliation and stress-corrosion cracks.

What are the different methods of inspection used in the detection of corrosion in aviation?

Visual, liquid penetrant, magnetic particles, ultrasonics and eddy currents are some of the inspection techniques generally applied. Other techniques such as tomography, holography, and shearography have gained less attention because it require large computerized equipment.
