True or False: Using compressed air is the preferred cleaning method because it prevents contamination spread.

Using compressed air as a cleaning method is generally discouraged because it can inadvertently spread contaminants rather than prevent them. When compressed air is used to blow dust, dirt, or other particles from one surface, it may transfer these contaminants to other areas of the aircraft or workspace, leading to potential issues such as corrosion, reduced performance, or other safety hazards.

Best practices for aircraft maintenance and cleaning often emphasize avoidance of methods that can propagate contaminants. Instead, cleaning methods that capture particles without dispersing them—such as using wipes, vacuums, or foam—are typically preferred.

While there may be specific situations where compressed air could be used with caution to address certain types of debris, these instances are limited and require strict protocols to mitigate the risks associated with its use. Overall, the default position regarding compressed air as a cleaning method leans toward it being potentially harmful in terms of contamination control.
