Is compression wood suitable for structural repairs in aircraft?

Compression wood is not suitable for structural repairs in aircraft. This type of wood has unique characteristics due to the way it forms in response to external pressures. It exhibits various defects such as irregular grain patterns, reduced strength, and impaired stability compared to standard timber. These factors significantly compromise the structural integrity that is essential in aircraft applications, where safety and reliability are critical.

Using compression wood in structural areas of an aircraft could lead to catastrophic failures, since the aircraft structure is designed to endure significant stresses during operation. Utilizing materials that do not meet stringent standards for strength and stability in aircraft construction and repair is unacceptable.

The other options may suggest limited usage of compression wood, but they still endorse aspects of its use in contexts that could be unsafe or inappropriate for aviation standards. Therefore, the clear stance is that compression wood should not be used in any structural repairs within an aircraft.
