Before drilling the pilot holes into the doubler, what must you ensure regarding the layout tape?

Before drilling pilot holes into the doubler, it is essential to remove the layout tape. The layout tape serves as a guide for marking the positions where drilling will occur; however, leaving it in place during the drilling process can interfere with the accuracy and cleanliness of the holes. The tape might cause misalignment or prevent the drill bit from achieving a clean entry, which is crucial for the integrity of the assembly.

Additionally, if the tape is left on, it may not withstand the drilling process and could cause issues such as wrapping around the drill bit or creating debris, which can jeopardize both the workpiece and the equipment. Thus, ensuring that the layout tape is removed allows for a clear and unobstructed area for drilling, leading to a more precise and professional finish on the assembly.
