What type of inspection is performed before applying fabric?

Performing a visual inspection before applying fabric to an aircraft structure is crucial because it allows for the identification of any damage, wear, or irregularities that could compromise the integrity of the fabric covering. This inspection ensures that the surface is sound and free from defects that could lead to issues like tearing, instability, or improper adhesion of the fabric.

The visual inspection focuses on checking for cracks, corrosion, or any other potential defects in the underlying structure. By identifying and addressing these issues beforehand, technicians can ensure a successful fabric application and maintain the overall safety and performance of the aircraft.

While other processes like cleaning, structural analysis, and chemical testing are important in the fabric covering process, they do not directly address the immediate condition of the underlying structure that the fabric will be applied to. A thorough visual inspection is essential to set a solid foundation for the fabric application, ultimately ensuring the aircraft's reliability in the air.
