Best Practices for General Aviation Aircraft Fuel-Tank Sampling

This report presents the results of Airport Cooperative Research Program (ACRP) Project 11-02, Task 22, “Best Practices for General Aviation Aircraft Fuel-Tank Sampling.” As part of a typical general aviation (GA) internal combustion engine preflight inspection, the pilot normally takes fuel samples from fuel system drains (a.k.a. “sumps”) and visually inspects them for color and contamination. Although these fuel samples can be returned to the fuel tank if they are uncontaminated, or disposed of in an approved container if contamination is found, it is generally acknowledged that many pilots simply discard the fuel samples to the ground surface regardless of whether contamination was identified or not. This disposal practice is inconsistent with many airport pollution prevention procedures and environmental regulations and can lead to stormwater runoff contamination and air pollution. ACRP Project 11-02, Task 22 was commissioned to evaluate this disposal practice, and specifically, to accomplish the following two objectives: 1) estimate the discard amounts from fuel testing samples that are entering the stormwater runoff system; and 2) develop a variety of airport and aviation best practices of aircraft fuel-tank sampling to prevent contaminants from entering the stormwater runoff system. Objective 1 was accomplished by conducting pilot surveys, field-based research, and mathematical calculations and Objective 2 was accomplished by performing literature reviews, inquiries and field testing, and preparing this Digest.
