Aerometals has secured its long-awaited supplemental type certificate (STC) approval for its Sikorsky S-92 inlet barrier filter (IBF). The STC culminated a five-year certification process that involved some 100 hours of flight testing and a $6 million investment on the part of the El Dorado Hills, Calif.-based aerospace parts manufacturer.

The STC was Aerometals’s most extensive and costly process yet, as the manufacturer worked with the FAA to satisfy certification requirements. The process had slowed as the FAA has been ironing out its policy guidance on approvals for rotorcraft IBFs. “It really has been a huge undertaking for us,” said Aerometals executive director Lorie Symon. “We’ve learned a lot. The FAA has learned a lot. It is really going to give us a good basis going forward…on how we can streamline these processes and make them more efficient.”
