MPLANES founder Jason Mulcock started his career at British Airways after having completed an Engineering Degree in the UK.  Here he drove efficiency and cost reduction initiatives on the fleet of Boeing 747-400s and assisted in the introduction of the Boeing 777.  With his team of 60 engineers he was responsible for the punctual operation of all long haul fleets including Concorde where he learned about the intricacies of supersonic flight.  British Airways encouraged ‘thinking out of the box’ which is a trait Jason has used to great effect ever since in his managerial positions and in his daily life.

The simple, fast, cost effective, under wing, go no-go test kit for the detection of microbial contamination to aid airworthiness procedures.

For owners and repairers (MROs) of business and/or private jets, microbial contamination, commonly known as ‘jet fuel fungus’ is a big issue which needs to be kept under control.

Microbial contamination can grow, especially in hot and humid climates, in just a few weeks so from what was a ‘clean’ tank to a heavily contaminated tank could be much faster than you anticipated. Testing only on suspicion of contamination may be too late resulting in heavy costs and operational delays.


FUELSTAT® Result will not only enable a fully transparent and traceable audit trail to track trends and hotspots, but also provide accurate information to enable effective and more cost-efficient maintenance programs to be undertaken.

Over 100,000 FUELSTAT® tests are used every year all over the globe in many highly regulated industries to monitor microbial contamination in middle distillate fuels. It is compliant with ASTM D8070 International Standard and is a listed product in many industry guidance documents such as IATA, JIG etc.




FUELSTAT® offers the fuel supply chain a simple, rapid alternative to sending samples for testing off-site for days or even weeks and gets around the fact that often site conditions are not sterile with the risk of samples getting cross contaminated.

The importance of testing under the wing is emphasised by ASTM D6469 which highlights that if a sample cannot be tested on-site it should be transported on ice and tested within 4 and no more than 24hrs or the sample may no longer be a true representation of the environment from which it came.


FUELSTAT® has OEM listings from
Airbus, Boeing, Bombardier, Embraer, Fokker, amongst others
