How often should wood used in aviation be inspected for maintenance?

Wood used in aviation should be inspected regularly, as the frequency of inspections must align with the level of usage and exposure that the wood is subjected to. This approach recognizes that environmental factors, such as humidity, temperature fluctuations, and exposure to moisture, can significantly impact the integrity and strength of the wood. Regular inspections help to identify any signs of wear, rot, or other types of damage that can develop over time due to these conditions. The interval between inspections will vary based on how often the aircraft is used and the conditions it is exposed to, making a one-size-fits-all schedule insufficient.

Other options suggest either a fixed timeline that may not account for usage (like every 10 years), an inspection only when problems arise, which risks delaying necessary repairs, or a rigid monthly schedule that doesn't consider actual conditions and usage patterns. Regular inspection adapted to real-world conditions ensures that the wood can maintain its structural integrity throughout its operational life.
