• FAA ends single pilot exemptions for certain Cessna Citation aircraft.
• Decision affects aerial firefighting operators using Citation air attack platforms.
• Adding a second pilot could conflict with federal contract specifications.
• Operators may need to replace affected aircraft or develop new configurations.

This decision may indicate a shift in FAA regulatory priorities, which could impact the aerial firefighting industry's ability to operate efficiently. The requirement for a second pilot suggests a focus on safety, but it may also create operational challenges for air attack missions, which could lead to changes in the way these operations are conducted.
