 the jet fuel fungus problem
Microbes thrive wherever there is food and water. Aviation fuel
systems are therefore ideal habitats for bacteria, yeasts and moulds.
Bugs which grow unchecked can block fuel filters, cause gauging problems
and are so corrosive, they can damage the aircraft tank structure.
the jet fuel fungus test
All you need is 10 minutes, a flat, clean surface, a pair of latex
gloves & a 200 ml sample to discover which bugs are living in
your fuel. The easy to interpret, pregnancy-style test gives a negligible,
low or high reading which corresponds to the limits laid down in
the IATA Guidance Material on Microbial Contamination in Aviation Fuel tanks. This clearly indicates the aircraft’s
fuel system status, and what action to take, if any. |
 the jet fuel fungus solution
There is no magic bullet to eliminate the problem. A multi-disciplinary
approach to fuel hygiene is the
key to avoiding the inconvenience
and cost of a contaminated fuel tank. Good fuel hygiene entails implementing
a risk assessed “rigid housekeeping regime”. The risk of contamination
is increased in hot, humid conditions, especially where fuel comes
from a source that has fewer quality control checks. Each airline
should carry out its own risk assessment to establish an optimum
regime. The selected regime should consist of regular water drain
checks and at least an annual test of the fuel in every tank, followed
by an appropriate fuel tank treatment, if required. Moderate levels
of contamination require the use of an approved biocide. Heavy levels
of contamination require the tank to emptied, cleaned and a biocide
applied. |
