Indicated by the depth of grooves in the tyre tread.

Movement of the tyre around the rim due to heavy braking.

Re-treading can occur if the tyre is not badly damaged.

The reduction in thickness of the brake pack over time.

Excessive heat can cause stator material to break up.

Brake units should be inspected between flights for wear and heat signs.

Debris, powder, or scoring on discs suggests brake issues.

Usually caused by impact damage or corrosion from landings.

Aircraft components that can vary in size and may be faulty due to wear or damage.

Examination for corrosion, especially at fastener holes and seams of doors and panels.

Specialized fasteners used on aircraft doors that require specific tools for operation.

A mechanism that shows if a protective cover has been opened or operated, often involves frangible devices.

Aircraft areas that experience pressure differences, requiring careful inspection for stress and damage.

Cracks developed due to constant cyclic loading, often found around doors and cut-outs.

Safety features on aircraft designed to release pressure, needing regular checks for serviceability.

Repairs to aircraft skin that require evaluating the surrounding structure for hidden damage.

Inspection process involving nicks, cracks, cleanliness, and lubrication.

Damages on the leading edge of the propeller blade that cause stress.

Examine engine temperatures, RPM, and unusual noises during ground operations.

Components with a specific lifespan that need replacement during servicing.

Specific locations in aircraft where corrosion is most likely to occur.

Unique susceptibility to corrosion in magnesium and aluminum alloys.

Regular checks are vital for light bulbs, especially for safety functions.

Corrosion risks in areas exposed to gas turbine and piston engine exhaust.

Spillage of chemicals from NICAD or Ni-Fe batteries, usually potassium hydroxide.

Neutralizing alkali with chromic acid in water and following health procedures.

Mercury quickly corrodes aluminium, causing pitting and intergranular attack.

Mercury combines with aluminum, leading to liquid metal embrittlement.

Using X-rays to locate spilled mercury due to its density.

Mercury leakage can damage structures and cause serious corrosion.

Fast isolation and recovery of mercury to prevent damage.

Mercury can breach coatings and finishes, leading to structural damage.

Indicates a need for maintenance and potential corrosion.

The most practical way to control steel corrosion.

Includes abrasive papers, power buffers, and wire brushes.

Corrosion here can be dangerous and requires careful removal.

Reapply protective finishes after corrosion removal.

Toxic dust that can cause serious illness if disturbed.

Cadmium-contaminated materials must be properly disposed of.

Ensure corrosion is within acceptable limits for safety.

Adjust air pressure and fluid valves for optimal spray pattern.

A correctly adjusted spray gun should create a consistent fan shape.

Start painting edges first, moving the gun steadily parallel to the surface.

Hold the spray gun about 20 cm (8 in.) from the surface.

Each spray pass should overlap the previous by two-thirds for uniform coverage.

Corrosion needs an anode, cathode, electrolyte, and electrical contact.

Prevent corrosion by removing one of its basic requirements.

Test and adjust the spray pattern before actual painting.
