What common inspection method is used to detect fabric failure?

The method of conducting tension tests for fabric tautness is effective for detecting fabric failure because it assesses the integrity and strength of the fabric under stress. When fabric is taut, it should exhibit a specific level of resistance to tension. If the fabric has deteriorated or developed weaknesses, it will not hold tension as expected, which can indicate tears, abrasions, or other forms of degradation. This makes tension tests a reliable way to ensure that the fabric covering maintains its necessary structural integrity for safe aircraft operation.

In contrast, other inspection methods like visual inspection may identify surface defects but might miss issues that are not visibly apparent. Weight checks of the fabric do not provide specific information about the fabric’s structural integrity and could lead to misinterpretation of the condition, especially if the weight has not changed significantly despite underlying deterioration. UV exposure testing can be useful for assessing the effects of ultraviolet light on fabric over time but does not directly evaluate the fabric's current state in relation to overall tautness or integrity. Thus, tension tests stand out as the most comprehensive method for detecting potential fabric failures.
