True or False: Sealants must withstand structural loads during flight and ground operations that cause twisting and bending.

Sealants used in aerospace applications are critical for ensuring the integrity of structures and systems by preventing the infiltration of moisture, bacteria, and other contaminants. For this reason, they must possess certain mechanical properties that allow them to perform effectively under various conditions.

During both flight and ground operations, aircraft experience a range of structural loads due to aerodynamic forces, weight distribution, and shifting during maneuvers. As aircraft operate, they can encounter twisting and bending forces that could potentially impair structural integrity and lead to failures if not properly managed. Sealants need to remain effective and maintain their adhesion and flexibility despite these stresses to function optimally.

Furthermore, the environmental conditions faced during flight, such as pressure changes, temperature variations, and vibration, also demand that sealants maintain their performance under significant loads. Thus, the requirement for sealants to withstand structural loads, both in flight and during ground operations, makes the assertion true.
