Eagle Fuel Cells

What Eagle Fuel Cells does

Eagle Fuel Cells is a privately held aviation component manufacturer operating from a single facility at Eagle River Union Airport in Eagle River, Wisconsin. The company specializes in flexible bladder-type fuel cells for general aviation aircraft, manufacturing FAA-PMA certified replacement cells using proprietary multi-ply seamless construction with synthetic rubber blends (nitrile/Buna-N based) upgraded since 2010 for compatibility with future 100UL unleaded aviation fuels. The firm holds FAA Certified Repair Station (NL5R071N) and EASA maintenance organization (EASA.145.6562) credentials, with supplemental type certificates covering Cessna 100/200, Piper PA-23, and Beechcraft installations.

The product portfolio spans new PMA replacement fuel cells, factory overhauled cells (three-day standard turnaround), major overhauls for rare and obsolete cells, custom bladder fabrication (5,000+ projects completed), and TSO-C76b certified fuel drain valves (FDV2 and FDV4 series). Revenue is generated through hardware sales, hourly-rate repair services, and an exchange program; pricing is not publicly disclosed except for the $275 FDV2 Cessna kit. Distribution combines direct-to-customer phone/email ordering with a national FBO installer network and trade show presence at Sun N Fun, AirVenture, and the Great Alaska Aviation Gathering.

The customer base is fragmented across individual general aviation aircraft owners, Fixed Base Operators performing installation, kit plane builders, and warbird restorers. The company is the exclusive distributor for Storehouse fuel drain valve products and operates with 11-50 employees under founder/management ownership, with no disclosed external funding, M&A activity, or leadership changes.

Products and services

• New PMA Fuel Cells FAA-PMA certified replacement bladder fuel cells for general aviation aircraft, manufactured using proprietary synthetic rubber blends and seamless multi-ply construction. Each cell carries a 5-year warranty against failure.
• Factory Overhauled Fuel Cells Factory overhaul service where leaking rubber is fully removed and new rubber is molded into the existing metal cell using heat and pressure (not patching). Standard turnaround is 3 days from receipt to return shipping; AOG overnight repairs are often turned around same day for minor work.
• Fuel Cell Repair Services Repair services to FAR standards priced at hourly rate plus material cost. Includes free no-charge evaluations (cleaning, testing, inspection) that return a condition report, life expectancy estimate, and alternative options before any work is performed.
• Major Overhauled Fuel Cells FAA-authorized major overhauls for rare, unavailable, or obsolete aircraft fuel cells. Process builds new bladder construction while incorporating original salvageable metal components from the existing cell.
• Custom Fuel Cells Custom-designed fuel bladders for non-production applications including kit planes, custom aircraft designs, classic aircraft rebuilding, and warbirds (T-6, T-28, T-34 series). Eagle Fuel Cells has 35+ years of experience and 5,000+ unique projects completed.
• Fuel Drain Valves (FDV2/FDV4) All-stainless-steel fuel drain valves for general aviation aircraft, including the FDV-2 pin-actuated valve with Viton o-rings (TSO-C76b certified) and FDV-4 threaded hex-stock valve (direct replacement for CCA-1550, TSO-C76b certified). Distributed exclusively from Storehouse.
• FDV2 Valve Kits Stainless steel drain valve kits available for Beechcraft, Cessna, and Piper PA-23 aircraft.

Direct peers

• Hartzell Engine Technologies: Hartzell Engine Technologies (HET) is a leading PMA manufacturer of FAA-approved aerospace engine accessories and fuel system components for general aviation, including turbochargers, starters, and fuel-related accessories. It is a direct peer as it sits in the same FAA-PMA replacement parts category, supplies the same GA owner/operator customers, and competes on certified alternatives to OEM parts.
• Precision Aviation Group (PAG): PAG is an MRO and PMA parts provider specializing in aviation accessories, avionics, fuel systems, and hydraulics with FAA Part 145 repair stations across the U.S. Direct peer: FAA-certified MRO + PMA model targeting the same fixed-wing/helicopter owner and FBO customers, often solving the same aftermarket and obsolescence pain points as Eagle.
• Champion Aerospace: Champion Aerospace (L3Harris) manufactures FAA-PMA ignition components, oil pumps, and fuel system hardware for piston-engine general aviation aircraft. Direct peer: same PMA business model, same Cessna/Piper/Beechcraft customer base, and overlap in fuel-accessory categories sold to mechanics and FBOs.
• AVStar Aircraft Services: AVStar Aircraft Services operates FAA-certified repair stations focused on fuel system overhauls, fuel cell refurbishment, and PMA replacement components for general aviation aircraft. Direct peer: identical fuel cell/bladder service offering, identical GA customer base, and direct substitution competitor in the overhaul-and-PMA niche.

Emerging players

• Aircraft Spruce & Specialty Co. Aircraft Spruce is a large catalog distributor of general aviation parts and PMA components, including fuel cells, fuel accessories, and installation kits sold direct to owners and FBOs. Emerging/distribution peer: resells many of the same PMA brands Eagle competes with and provides an alternative channel where Eagle's fuel cells are also listed, making it both a partner and competitor.

Broad incumbents

• Crane Aerospace & Electronics: Crane Aerospace & Electronics manufactures fuel management and sensing systems, hydraulic components, and related subsystems across commercial, business, and military aviation. Broad incumbent: same aerospace fuel management domain and similar quality/regulatory posture, though Crane serves higher-volume platforms rather than the small-fleet GA aftermarket.
• Continental Aerospace Technologies: Continental Aerospace Technologies is an established OEM manufacturer of certified piston engines and selected replacement subsystems (including fuel system components) for the general aviation market. Broad incumbent: serves as the OEM Eagle frequently replaces, and competes indirectly via its factory-overhaul and replacement-part operations alongside its engine business.
• TransDigm Group: TransDigm owns a portfolio of aerospace component businesses (including Aeroquip fuel hoses, couplings, and proprietary aerospace accessories) serving both OEM and aftermarket channels. Broad incumbent: comparable aerospace fuel system and component business with proprietary-parts / aftermarket margin model, but operates at vastly larger scale across multiple aviation segments.
• Eaton Aerospace: Eaton Aerospace designs and manufactures fuel system components, including fueling valves, coupling systems, and fuel management hardware across commercial and military aviation. Broad incumbent: same aerospace fuel system domain, much larger portfolio and scale, with some overlap on fuel drain valve technology relevant to Eagle's FDV product line.
• Parker Hannifin Aerospace: Parker Aerospace is a major Tier-1 manufacturer of fluid systems, including aerospace fuel lines, valves, couplings, and bladder/containment components used on commercial, business, and general aviation platforms. Broad incumbent: comparable aerospace fuel-system componentry, much larger scale, but doesn't focus on GA aftermarket PMA cells where Eagle operates.
