An aircraft fuel tank provides the perfect conditions for microbiological contamination to develop, especially when operating in hot and humid environments. Problems caused by microbiological contamination of fuel can range from inaccurate or erroneous fuel quantity readings to structural corrosion and engine fuel supply difficulties caused by clogged fuel filters.
As a result, if treatment is not correctly applied, microbiological contamination can also cause significant safety issues. This article describes why prevention is important and focuses on why it is essential to follow the maintenance procedures when treatment is required.
