Aerometals

Aerometals is a helicopter filtration and parts company based in El Dorado Hills, California. It designs, flight tests, certifies and manufactures engine inlet barrier filter (IBF) systems and FAA PMA replacement parts, and its site describes it as responsible for every aspect of the design from concept to certification.

Inlet barrier filters

The company says its IBF systems are in operation on more than 5,000 airframes and have accumulated an estimated 20 million flight hours, with nearly 100 percent vertically integrated manufacturing. Single engine filter systems listed on its site cover these types:

• Airbus Helicopters: AS350B, AS350D, AS350FX, EC120, EC130 and H130
• Bell: 206A, 206B, 206BIII, 206L and 407
• MD Helicopters: MD500 and MD600

Newer programs include twin engine filters for the H-60 / S-70 and the H225. A press release dated March 2026 says the H225 filter program was completed and entered production, and an earlier release announced development of a filter for the Bell 412EP.

PMA spare parts

Aerometals provides FAA Approved PMA replacement parts for several helicopter models, mainly MD500 series items such as engine cooling ducts, deflectors, fan shafts and hubs, scissors links and a seat pan modification. A customer portal supports quotes, online ordering and access to technical data including service bulletins, flight manual supplements, PMA supplements, STCs and installation instructions.
