Study Notes
Aircraft Construction Materials
- Wood was among the first materials used to build aircraft.
- Most World War I aircraft were not constructed of metal frames; wood was predominant.
- Wood remained the preferred material for aircraft construction until the 1930s due to a lack of suitable corrosion-resistant materials.
Wood Structure Inspection
- Inspection should occur in a dry, well-ventilated hangar, not in wet or poorly ventilated conditions.
- Proper inspection practices are essential for maintaining the integrity of wood structures.
Borescope Usage
- A borescope is an optical tool designed for visual inspection of narrow, hard-to-reach cavities.
- It aids in identifying potential issues within wood structures.
Moisture Content in Wood
- The ideal moisture range for wood in aircraft structures is 8-12%, not 15-20%.
- Maintaining the proper moisture level is crucial for durability and strength.
Adhesive and Joint Integrity
- Glue can deteriorate over time due to aging, extreme temperatures, and mechanical forces.
- Darker-colored aircraft accumulate higher skin temperatures and increased heat buildup.
- Glued joints are not typically designed to bear compression loads and may fail under excessive mechanical loads or accidents.
- For effective bonding, adhesive should be applied to both surfaces, contrary to a common misconception.
Wood Types and Adhesive Requirements
- Common wood types used in aircraft construction include solid wood, high-density plywood, and laminated wood.
- Surfaces must be clean, dry, and free from contaminants like grease, oil, wax, and paint for proper adhesion.
Inspection Techniques
- Tapping the subject area with a light plastic hammer helps differentiate between solid and hollow sounds, indicating potential issues in the structure.
- Various factors contribute to glue deterioration, such as chemical reactions from aging, mechanical stresses due to wood shrinkage, and fungal growths.
