Which activity is allowed on an airport?

• A. Airlines can perform maintenance on any aircraft
• B. Aircraft Owners can provide preventative maintenance to their own plane and can self-fuel
• C. General public can refuel any aircraft
• D. Only FAA-approved maintenance firms may perform any maintenance

Answer: (B)

The question tests who is allowed to do certain maintenance and fueling on an aircraft. Aircraft owners can perform preventive maintenance on their own aircraft and can refuel it themselves. This is allowed under FAA rules for light, routine tasks and self-fueling, as long as the work is within the owner’s capabilities and proper records are kept. Major repairs or alterations require a certificated mechanic or approved facility, not the owner swinging any task they want.

The other options overstate or misstate the rules: airlines don’t have carte blanche to maintenance any aircraft, the general public isn’t allowed to refuel any aircraft, and maintenance isn’t restricted solely to FAA-approved firms—owners can handle some maintenance themselves within allowed limits.
