Which condition often indicates that wood is compromised?

The correct indication that wood is compromised is often geometric distortion. This condition results when wood fibers are affected by moisture, temperature changes, or physical stress, leading to warping, bending, or mixing of dimensions from the original specification. Geometric distortion can significantly affect the structural integrity and load-bearing capacity of wooden components in aviation applications, where precision is crucial. Additionally, it can impair the overall performance and safety of the aircraft, as misaligned or distorted parts may not fit properly or function as intended.

While poor odor, loss of natural sheen, and framework displacement can indicate associated issues with wood, they do not specifically point to wood being structurally compromised in the same direct way that geometric distortion does. Odor may suggest decay or mold but does not directly correlate with structural integrity. Loss of natural sheen can indicate aging or surface wear rather than a compromise in strength. Framework displacement may be a symptom of broader structural issues but is not limited to wood alone and could arise from various factors affecting the overall assembly of an aviation structure.
