22 OCTOBER 2018 AIRCRAFT MAINTENANCE TECHNOLOGY AIRLINE the elements under severe stress, to see how it reacts in operation. Finally, there are field trials. “Only after a new technology has passed all of these challenges is it fit for service,” Leonard says. “From the time you start your EI testing to the time you’ve passed field trials will probably take at least 12 months.” Currently, only the Dirt Defense has obtained EI certification. However, this solution still must go through industry testing. “A4A and JIG, which are the two governing bodies, have not accepted this solution as a valuable implemented device,” Muzik says. However, Wildschütz states this process should go smoothly, noting that the Dirt Defense uses “microfiltration technologies, which have been used in the industry for decades. “All of these new technologies, because they are new, are going to use a free water sensor qualified to EI-1598, just to make sure the systems are absolutely safe,” he continues. “That’s not only for the field trial but also in actual use. You may be in a situation later with different environmental issues, and you want to be sure your system is really safe, because you want to be sure you are delivering safe fuel to the aircraft.” Companies like Boeing, GE, and Rolls-Royce are calling the shots, however. They have said they will no longer allow SAPs after the deadline. If an airline continues to use them and an incident occurs, the airline will be held liable. “If they [engine manufacturers] won’t accept SAP, then the airlines cannot accept it, and it gets pushed down to everyone in the industry to correct the problem,” says Dan Murray, president of Total Control Systems. “I’d love to tell you that the industry is ready for this, but I think the reality is that Total Control Systems is ready. Our electronic automation and control can measure differential pressure and water in the fuel. We can provide trending and analysis for companies to manage their maintenance schedules, and while that’s a critical piece, the filtration companies will need to provide the solution to remove water in fuel.” But what if these fuel filtration players cannot meet the 2020 deadline? Leonard looks to what happened when the EI-1583 7th Edition came out. This standard said that under normal operating conditions an SAP cannot pass more than 50 parts per billion downstream.
