El Dorado Hills, Calif.-based FDC/aerofilter has obtained an EASA supplemental type certificate (STC) for its inlet barrier filter (IBF) system on the Eurocopter EC135. The approval comes in anticipation of two large European fleet operators that are scheduled to receive the system. The IBF is on the Air Methods fleet in the U.S., and is also in service with operators in Australia, Brazil, India and South Korea. FDC/aerofilter provides filters for a number of other types, including the Bell 206 and 407, MD500/600, Sikorsky S-76 and Soloy/Honeywell AS350 conversions.
