What is a potential consequence of performing maintenance during fueling?

Performing maintenance during fueling presents increased safety risks, which is a critical concern in aviation operations. Fuels are highly flammable, and any maintenance activity could introduce sparks or other potential ignition sources. For example, an open circuit caused by maintenance work or equipment not being properly handled can create a fire hazard.

Additionally, there could be distractions due to the maintenance tasks, leading to lapses in the attention required for fueling procedures. Proper grounding and bonding are often essential when fueling, and if maintenance disrupts these processes, it could culminate in catastrophic outcomes. Therefore, maintaining a strict protocol that separates fueling from maintenance is vital to minimize risks to personnel and equipment.
