Which aspect of aircraft maintenance can be negatively impacted by inadequate moisture control?

Inadequate moisture control can significantly impact the performance of filler material. Filler materials are used in various applications within aircraft maintenance, including surface repairs and bonding processes. When moisture is present, it can lead to a range of problems, such as reduced adhesion strength, premature failure, or improper curing of the filler material.

For instance, if moisture is trapped within or around the filler material, it can cause the material to expand or weaken, leading to compromised repair quality and reduced overall structural integrity of the aircraft. This is particularly critical in low observable aircraft, where any imperfections could affect radar cross-section and stealth capabilities. Hence, maintaining strict moisture control is essential to ensure that filler materials perform optimally and that repairs are durable and effective.
