Enstrom Helicopter Corporation has received full FAA certification for the crash resistant fuel system (CRFS) on its 480B turbine-powered helicopter. This achievement enables Enstrom to resume sales of newly produced 480B helicopters to the global market.

The US Congress had previously approved an FAA mandate requiring all helicopter manufacturers to implement CRFS technology into new helicopters. The CRFS is designed to minimise the risk of post-impact fuel fires during crashes and is comprised of a new type of bladder material, break away fittings to close off fuel lines and reinforced structural elements to protect the fuel system from penetration and leaking.

“This certification marks a pivotal moment for Enstrom as we reaffirm our commitment to safety and innovation, protecting pilots, passengers and crew,” says SVP of product, sales and customer excellence Charles Wade. “The 480B has long been a trusted platform for flight training, law enforcement and personal transport. Not only are we exceeding modern regulatory demands, but we’re also delivering enhanced survivability that customers can rely on in the most demanding environments.”

This FAA validation occurred simultaneously with validation from EASA. EASA authorities are finalising a package in the coming weeks to signify full compliance. Once complete, Enstrom will fully re-enter the European helicopter market.

Enstrom partnered with Safran Aerosystems in developing and supplying the fuel bladders the necessary components for the CRFS. Safran also managed product-level testing to support Enstrom’s aircraft-level certification.

This certification also paves the way for FAA approval of the CRFS developed for Enstrom’s piston-powered 280FX model, for which Enstrom and Safran Aerosystems are working together closely.

Wade adds: “We are in the final stages of ground and flight test for the CRFS in the 280FX, with a Q1 2026 target for certification. This will enable sales of newly produced 280FX helicopters globally.”
