Which of the following is a potential consequence of improper sealant application?

The potential consequence of improper sealant application that is identified as correct is the leakage of fluids. Sealants are used in aerospace applications to create a barrier against fluids, such as fuel and hydraulic fluids, and to prevent ingress of moisture or contaminants. If the sealant is not applied correctly—whether due to improper surface preparation, incorrect application technique, or using the wrong type of sealant—this can lead to gaps or weak points. These weaknesses can allow fluids to leak, which not only compromises the integrity of the system but can also lead to operational hazards, such as fuel loss, environmental contamination, or system failure.

While the other options suggest benefits like improved airflow or enhanced structural strength, they don't relate to the consequences of improper application of sealant. Additionally, the idea that there would be no effect at all contradicts the fundamental purpose of sealants in aerospace applications. Therefore, understanding the critical role of proper sealant application in preventing fluid leaks is vital for maintaining safety and performance in aerospace systems.
