What is the maximum distance allowed between a fastener and the tie point?

The correct choice indicates that the maximum distance allowed between a fastener and the tie point is six inches. In aerospace assembly, adhering to specific guidelines regarding fasteners and tie points is crucial for ensuring structural integrity and safety. The tie point serves as a key reference location for attaching components, and maintaining this distance helps to ensure that the fastener can effectively transfer loads and resist any movement or failure during operation.

By keeping the maximum distance at six inches, designers and engineers can minimize the risk of compromising the assembly's stability and performance. This standard also reflects best practices in the industry, where precise tolerances and careful consideration of material strength play a significant role in aircraft safety. Understanding these regulations is essential for anyone involved in aircraft assembly or maintenance, as they help prevent potential issues related to mechanical failure or structural weaknesses.
