What Raisbeck Engineering does

Raisbeck Engineering is a Seattle-based aerospace company that designs, develops, certifies, and markets FAA Supplemental Type Certificate (STC) performance modification systems for business and commercial turboprop aircraft, with a primary focus on the Beechcraft King Air family and Cessna Caravan 208B. Its product portfolio is organized around branded "EPIC" performance packages — Platinum, Gold, and platform-specific configurations — that bundle individually-certified aerodynamic and propulsion upgrades including swept-blade composite propellers (manufactured with Hartzell Propeller), the Ram Air Recovery System (RARS), Enhanced Performance Leading Edges, Dual Aft Body Strakes, High Flotation Gear Doors, Crown Wing Lockers, and Auxiliary Heading Selector Systems. Several of these systems are OEM-standard on new-production King Air 250/260/350/360 and C90GTx aircraft, and the company also holds FAA Parts Manufacturer Approval (PMA) for direct-replacement Beechcraft parts and EASA/ICAO certifications for international operators.

The company's business model is built on one-time hardware sales of certified modification kits, supplemented by ongoing parts/components revenue and technical/installation support services. Pricing is quote-based and varies by aircraft platform and modification scope, with sales conducted through a global network of 140+ authorized dealers spanning North America, Europe, LATAM, Africa, and Asia-Pacific, supported by a regional direct-sales team. Raisbeck generates revenue across two primary customer segments — business aircraft operators (corporate flight departments, charter operators, individual owners) and commercial operators (cargo and passenger turboprop services) — with secondary extensions into military platforms. The product mix is being actively broadened through new partnerships: exclusive global distribution of Metrea's STC portfolio (Twin Commander, expanded Caravan, B300 gross weight/cargo pod), CiES fuel quantity indication systems for both King Air and Caravan, and a recently launched Cargo Pod Exhaust Shield.

Raisbeck was founded in 1982 by James Raisbeck and operated independently for 35 years before being acquired in 2016 by Acorn Growth Companies, a private equity firm focused exclusively on Aerospace, Defense, and Intelligence. Under PE ownership, the company has expanded its U.S. footprint to include operations in New Hudson, Michigan and Raleigh, North Carolina, and has pursued an aggressive product-portfolio and dealer-network expansion strategy. Leadership transitioned in August 2025 with the appointment of Gregory Davis — a former pilot and aerospace engineer — as President, succeeded by a brand refresh initiative led by agency-of-record AVNAT in 2026.

Core offering

Raisbeck Engineering designs, develops, manufactures, and markets FAA STC-certified performance modification systems for business and commercial turboprop aircraft, primarily Beechcraft King Air and Cessna Caravan models. The company offers bundled EPIC performance packages and individual systems (swept-blade propellers, aerodynamic surfaces, storage lockers, fuel quantity systems, and avionics add-ons) that are sold to aircraft operators globally through a network of 140+ authorized dealers and direct field sales.

Product overview

Raisbeck Engineering is a globally-recognized leader in aircraft performance modification systems for business and commercial aircraft. The company offers a coordinated portfolio of synergistic performance packages (EPIC packages) and individual systems/engineered products, along with PMA parts. The core EPIC package architecture combines multiple individually-certified performance systems — including swept blade propellers, aerodynamic strakes, leading edges, gear doors, and wing lockers — that work together to enhance takeoff, climb, cruise, and landing performance across specific aircraft platforms. Individual systems (Carbon Fiber 5-Blade Swept Propellers, Aluminum 4-Blade Swept Propellers, Power Props, Crown Wing Lockers, Dual Aft Body Strakes, Enhanced Performance Leading Edges, High Flotation Gear Doors, Ram Air Recovery System, Aft Fuselage Locker, Auxiliary Heading Selector System) can be purchased individually or as bundled EPIC packages for King Air 200/100/90/E90 series and Cessna Caravan 208B. Recent additions include fuel quantity system upgrades developed with CiES Inc. for both King Air and Caravan, Metrea STC modification products for King Air, Caravan, and Twin Commanders, and a Cargo Pod Exhaust Shield for Caravan B models. The company also distributes FAA PMA parts and maintains a global dealer network of over 140 authorized locations.
