Fuel tank flammability protection

Marshall Aerospace and Defence Group consults on, designs, installs and certifies fuel tank flammability protection systems for military and civilian aircraft. Our solutions meet military (Def-Stan 00-970) and civil (FAR 25) requirements. 

Our experience means we can evaluate a number of different solutions and advise you on the most appropriate for your needs. 

Overview of civil aircraft requirements

FAA regulations introduced in 2008 mean that all new civil aircraft have suitable flammability protection systems installed in the fuel tanks. Most legacy aircraft will have to undergo modifications. This approach is also being adopted by EASA so is expected to be incorporated into the airworthiness rules of all major airworthiness organisations. 

Overview of military aircraft requirements

While military aircraft operators are not subject to the FAA regulations, they still have a duty of care towards their personnel, and the need for continued operation during battle damage. This is particularly relevant for aircraft which operate in areas where there is a threat of ground attack. Military operators usually protect all fuel tanks and aim to eliminate ignition within them. 

Key solutions

There are two main methods of flammability protection: 

  • Ignition Mitigation Means – ignition is allowed but the effects are locally mitigated - in most instances by suppressant foam introduced to the fuel tank
  • Flammability Reduction Means − ignition is allowed but full flammable conditions are reduced – in most cases by an inert gas introduced to the fuel tank 

We have experience in analysing both methods of protection, the different solutions available, and their suitability for different aircraft. From start to finish, we provide a reliable analysis, design and installation service.
