- 38. TYPES OF REPAIRS •The type of repair to be made will depend on the materials, tools, amount of time available, accessibility to the damaged area, and maintenance level. The types of repair are permanent, temporary, and one-time flight (ferry). • Permanent repair is one that restores the strength of the repaired structure equal to or greater than its original strength and satisfies aerodynamic, thermal, and interchangeability requirements, This ensures the designed capabilities of the aircraft.
- 39. TYPES OF REPAIRS •Temporary repair restores the load-carrying ability of the structure but is not aerodynamically smooth or able to satisfy interchangeability requirements. This repair should be replaced by a permanent type as soon as possible in order for the aircraft to be restored to its normal condition. • One-time flight repair restores a limited load-carrying ability to the damaged structure in order to fly the aircraft to a depot maintenance activity for a permanent repair. When this type of repair is made, the aircraft cockpit should be placarded to limit the performance of the aircraft.
- 40. MACHINES & TOOLSUSED Shearing Machine • Sheet metal forming machine that used to cut sheet metal • Hydraulically powered • It works by first clamping the material with a ram • A moving blade then comes down across a fixed blade to shear the material Grinding Machine • A type of machining using an abrasive wheel as the cutting tool
- 41. MACHINES & TOOLSUSED Rolling Machine • Roll different kind of metal sheet into a round or conical shape Shrinking & Stretching Tools • Shrinking reduces surface area by thickening the sheet metal • Stretching increases the surface area and causes it to become thinner.
- 42. MACHINES & TOOLSUSED Tube Bending Machine • Round, rectangular or square tube • Factors involved in the tube bending process is the wall thickness, tooling and lubricants needed by the pipe and tube bender to best shape the material. Cable Swaging Machine • Attach fittings to pipes or cables • Parts loosely fit together, and a mechanical or hydraulic tool compresses and conforms the fitting, creating a permanent joint.
- 43. MACHINES & TOOLSUSED Lathe Machine • Rotates the workpiece on its axis to perform various operations such as cutting, sanding, knurling with tools that are applied to the workpiece to create an object which has symmetry about an axis of rotation. Drilling Machine • Motor driven device, fitted with an end cutting tool that is rotated with sufficient power either to create a hole in a solid material.
- 44. MACHINES & TOOLSUSED Rivet Guns • Also known as a pneumatic hammer, is a type of tool used to drive rivets. Hand cutting machine

- 46. Paint, or morespecifically its overall color and application, is usually the first impression that is transmitted to someone when they look at an aircraft for the first time. Paint makes a statement about the aircraft the person who owns or operates it.The paint scheme may reflect the owner’s ideas and color preferences for an amateur-built aircraft project, or it may be colors and identification for the recognition of a corporate or air carrier aircraft. Paint Shop:
- 47. Paint is morethan aesthetics; -it affects the weight of the aircraft and protects the integrity of the airframe. The topcoat finish is applied to protect the exposed surfaces from corrosion and deterioration. -a properly painted aircraft is easier to clean and maintain because the exposed surfaces are more resistant to corrosion and dirt, and oil does not adhere as readily to the surface.
- 48. Finishing Materials : Awide variety of materials are used in aircraft finishing. Some of the more common materials: -Acetone -Alcohol -Benzene -Methyl Ethyl Ketone -Linseed Oil Primers: The importance of primers in finishing and protection is generally misunderstood and underestimated because it is invisible after the topcoat finish is applied. A primer is the foundation of the finish. Its role is to -bond to the surface
- 49. -inhibit corrosion ofmetal - provide an anchor point for the finish coats Some of the various primer types are : -Wash Primers -Red Iron Oxide -Gray Enamel Undercoat -Urethane Preparation: -Surfaces -Primer and Paint -Adjusting the Spray Pattern -Applying the Finish That’s how the whole process of painting is done.
