THERE IS NEVER A GOOD TIME FOR FUEL CONTAMINATION

Mission-Critical Aviation Fuel 

With microbial contamination, it’s not a matter of IF, it’s a matter of WHEN. Regular monitoring of microbial counts in stored fuel and tanks is essential for making the right decisions on taking action to prevent problems. Second Generation ATP testing, and full-up Next Generation DNA Sequencing (NGS) allows you to discover things that you never could before.

Microbial Testing Services – the MBX Advantage

Aviation fuel is sometimes incorrectly assumed to be cleaner and more sterile than the fuels used in on-road or backup application. Yet, microbiological growth can occur at any stage in the jet fuel supply chain. In its life, jet fuel has multiple points of exposure to microbial growth risks. For aviation use, the consequences of these problems developing are unusually serious.

All along the aviation fuel supply chain, every stakeholder needs to remain aware of the potential and the risks that microbial contamination plays for aviation fuel – both its risks to aviation fuel quality and to aircraft operations and safety.

Microbiological contamination threatens everyone in the broader aviation sector: commercial airlines, private aviation operators, military personnel, airports large and small, MROs, FBOs, and aviation fuel suppliers.

Relevant industry associations like JIG and IATA do encourage a more pro-active approach towards how to manage this problem. Such approaches include preventing water accumulation in tanks –  an essential aspect that goes a long way towards minimizing the potential for contamination.

At the same time, there have been changes in the industry towards the options that are available – and not changes for the better. These have only increased the importance of the other key preventive steps all aviation stakeholders need to adopt. Not just water prevention but also microbiological testing of the fuel.

Condition Monitoring 

Gone are the days when taking care of stored fuel meant just ‘fill-it and forget it’.

MBX Lab Services can make things very easy for you. By providing complete onsite testing services using the industry leading test tools and equipment, you can be sure that you are getting the right information to make the right decisions quickly. We can also provide advanced laboratory analysis services as needed in order to isolate problems in your entire fuel chain.

Specifically concerning microbial contamination, today’s fuels are susceptible like never before due primarily to changes in the refining process as well as new government regulations.

ASTM Standard 7687

The latest fuel test methodology is also known as ASTM D7687 “Standard Test Method for Measurement of Cellular Adenosine Triphosphate (ATP) in Fuel and Fuel-associated Water with Sample Concentration by Filtration”.   There’s a reason why “best practices” and “ASTM” are inseparably linked. No matter what you need to know about your stored fuel, there’s a good chance you’ll need an ASTM test to get you there.

Testing Services Specifically for Aviation Applications

Common Fuel Problems for Aircraft

In any system, you are most likely to find microbes living on physical surfaces (like tank walls) and at interfaces between fuel and free water. When on surfaces, microbes live in and behind biofilm formations – slimy growths that house entire living ecosystems of microbes. It is this slimy growth that may also turn into particulate that is suspended in fuel and blocks filters.

Microbes Are Linked to Corrosion Damage

Microbes are a primary causal factor in instances of “MIC” – microbially induced corrosion. They do this by a variety of mechanisms –  some simple, some more complex. Aluminum structures in aircraft wings become corroded through the action of acids produced by microbes that live in these biofilm formations.

 

MIC damage in aircraft and aviation systems can be recognized by signs of pitting or etching on surfaces. It may also develop at a surprisingly fast rate. So monitoring is an essential element of staying ahead of this problem. Yet, metal structures in aircraft aren’t so easily accessible

Aircraft FQIS Malfunction

Central to the proper functioning of any aircraft is the Fuel Quantity Indicator System (FQIS), the series of fuel tank probes that provide fuel measurements to the cockpit through the plane’s centralized monitoring system.  These probes have proven to be susceptible to fouling by microbial growth in the fuel tank.

 

How? Microbial growth can foul the probes that provide the readings necessary for the system to correctly read the tank’s fuel level. More specifically, this growth interferes with the capacitance measurements the system interprets. If the FQIS can’t read things properly, it will return an incorrect reading to the cockpit or even a false indication of bad fuel quantity. 

 

Microbial Monitoring Cannot be Ignored

That’s why it’s so important to monitor the microbiological contamination levels of the fuel itself, through regular fuel testing as with ATP-By-Filtration.  The industry itself seems to concur – IATA recommends routine microbial testing, as do the AMMs for many leading aircraft manufacturers – Airbus, Boeing, Gulfstream, and others, both noncommercial and commercial.

FUEL STORAGE

Aviation Fuel Storage Considerations

Microbiological contamination of aviation fuel, especially stored aviation fuel, is an increasingly serious issue. Not only can it compromise the quality of the fuel, it can seriously damage tanks and systems – especially if it’s left unchecked for long enough that MIC (microbially influenced corrosion) develops.

 

Best Practices for Keeping Fuel Healthy

The best practices for keeping stored aviation fuel healthy intersects with many of the recommendations for preserving over-the-road fuel, but with a handful of key exceptions. Monitoring water levels and removal of free water is a universal recommendation. But the options for administering certain kinds of fuel preservation treatments are a lot more limited for aviation fuel.

 

Essential Microbial Testing

Precisely because of the limited options to solve microbial growth in aviation fuel, microbial testing of stored aviation fuel becomes a higher priority. Once a microbial problem is detected in an aviation storage tank, the microbial population is likely well established enough to require expensive remediation efforts – especially when the normal first option in the regiment, biocide, has such few options in aviation.

 

The most important thing is to monitor microbial populations in aviation storage tanks, giving you the ability to take action before they increase to the point where biomass, and corrosion damage develop. This is one of the value propositions of ATP-By-Filtration testing. It delivers accurate in-field microbial readings in less than 10 minutes, allowing aviation decision makers to make the right real-time decisions for their systems.
