How many points in each wing does the Cessna 172 have for fuel sampling?

The Cessna 172 has five points in each wing for fuel sampling, which is a design feature aimed at ensuring the integrity and quality of the fuel system. These sampling points allow for effective monitoring and inspection of fuel to detect contaminants or water that may have accumulated in the tanks. By having multiple sampling points, it increases the likelihood of obtaining representative fuel samples, making it easier to identify potential issues before takeoff. The presence of five sampling points is crucial for pilots to perform their pre-flight inspections thoroughly, ensuring safety and operational reliability. This design is part of the aircraft's safety measures to promote proper maintenance procedures and operational checks.
