Where is the oil capacity check performed?

• A. The refueling panel
• B. Engine oil filler cap
• C. Maintenance access panel
• D. APU bay

Answer: (A)

The check of engine oil capacity is performed at the refueling panel. This panel serves as the designated service point for ground servicing, and on this aircraft the engine oil quantity verification is done there so that oil level can be confirmed in conjunction with fueling and properly logged during one servicing step. The engine oil filler cap is used for adding oil rather than measuring total capacity. The maintenance access panel is for general maintenance access and isn’t the standard location for a capacity check. The APU bay is for the auxiliary power unit and its oil system, not the main engine oil capacity.
