Under what condition can the solvent wipe cleaning step for composite materials be omitted?

The solvent wipe cleaning step for composite materials can be omitted when it is authorized by the aircraft tech data. This is because technical data is specifically tailored to address the maintenance needs of the aircraft and its components. It reflects the established practices that have been evaluated and deemed necessary for ensuring the integrity and performance of the materials.

In situations where the tech data provides guidance on omitting the solvent wipe step, it typically implies that there is a scientific basis or previous testing to support this decision. Authorized procedures ensure that maintenance personnel are following the best practices for the specific conditions and materials involved, ultimately maintaining the safety and effectiveness of the aircraft.

The other conditions, while they may have relevance in different contexts, do not specifically align with the guidelines set forth in technical data, which is the definitive source for maintenance procedures.
