Identify a sign of fabric deterioration that would require immediate attention.

Choosing the option that refers to tears, excessive wear, discoloration, or brittleness highlights crucial issues that indicate fabric deterioration requiring immediate attention. These signs suggest that the structural integrity of the fabric is compromised, which can pose serious safety risks if not addressed promptly.

Tears or excessive wear can lead to larger rips or failure of the fabric during flight, while discoloration can indicate UV damage or degradation caused by environmental exposure. Brittleness often points to the fabric losing its flexibility and strength, making it more susceptible to failure under stress. Recognizing these signs early is essential to ensure the safety and reliability of the aircraft covering system. Proper maintenance and timely repairs can prevent further deterioration and extend the life of the fabric covering, ultimately contributing to the overall safety of the aircraft.

In contrast, signs like even color across the fabric or a firm texture with no visible damage suggest that the fabric is likely in good condition, and minor cosmetic issues, such as minor scuffs, are not indicative of immediate deterioration. Thus, they do not require the same level of urgency as the issues highlighted in the correct choice.
