What is one disadvantage of wood that manufacturers must consider during production?

One disadvantage of wood that manufacturers must consider during production is its susceptibility to rot if not properly treated or maintained. Wood is a natural material that can absorb moisture, making it vulnerable to fungal growth and decay. This susceptibility requires that wood used in aviation applications be treated with preservatives to increase its durability and resistance to environmental factors. Proper maintenance and treatment are crucial to ensure the longevity of wooden components, particularly in an industry where reliability and safety are paramount.

In contrast, the other options do not accurately reflect fundamental disadvantages associated with wood. While the cost of wood compared to metals could vary depending on the type of wood and metal being compared, wood can sometimes be more economical. Additionally, wood can often be repaired, and it is not inherently heavier than all composites; in fact, modern composite materials can vary widely in weight. However, the risk of rot remains a significant concern that must be meticulously managed in the production of wooden aviation components.
