Enstrom Helicopter Corporation has achieved full Federal Aviation Administration (FAA) certification for the crash-resistant fuel system (CRFS) on its 480B turbine helicopter — a milestone that officially clears the way for the company to restart sales of newly built 480Bs worldwide.

The certification aligns with a U.S. congressional mandate requiring all manufacturers to incorporate crash-resistant fuel technology into new-production helicopters. Enstrom’s CRFS incorporates advanced bladder materials, break-away fittings designed to seal fuel lines during impact, and reinforced structural components that reduce the risk of fuel leakage and post-crash fire.

“This certification marks a pivotal moment for Enstrom as we reaffirm our commitment to safety and innovation, protecting pilots, passengers, and crew,” said Charles Wade, Senior Vice President of Product, Sales, and Customer Excellence. “The 480B has long been a trusted platform for flight training, law enforcement, and personal transport. We’re not only exceeding modern regulatory demands, but delivering enhanced survivability customers can rely on in demanding environments.”

FAA approval was coordinated in parallel with validation from the European Union Aviation Safety Agency (EASA), with final compliance expected in the coming weeks — opening the door for Enstrom’s full return to the European market.

Development of the CRFS was carried out in partnership with Safran Aerosystems, which supplied the fuel bladders and managed component-level testing to support certification. The milestone also accelerates progress on the CRFS for Enstrom’s piston-powered 280FX. Ground and flight testing are nearing completion, with certification targeted for Q1 2026.

Wade added, “This will enable global sales of newly produced 280FX helicopters as soon as approval is secured.”
