How often should integral fuel tanks be inspected for potential leaks?

Integral fuel tanks, which are built into the structure of an aircraft, require periodic inspection to ensure safety and functionality. Regular inspections are vital to detect potential leaks or structural flaws that may develop over time due to factors like fatigue, corrosion, or other forms of wear and tear.

The manufacturer's guidelines provide specific schedules for inspections that take into account the operational environment of the aircraft, flight hours, and maintenance procedures. These guidelines are developed based on extensive research and testing, taking into consideration the design and materials used in the construction of the fuel tanks. Adhering to these recommendations ensures that any abnormalities or issues can be identified and addressed in a timely manner, maintaining the safety and efficiency of the aircraft.

Inspections that are based solely on operational flights or daily operations may not adequately capture leaks or issues that occur or develop over longer intervals. Similarly, inspections tied to refueling times may not reflect the overall condition of the tanks. Hence, regular inspections according to the manufacturer's guidelines offer a comprehensive and structured approach to maintaining the integrity of integral fuel tanks.
