What Finnoff Aviation Products does

Finnoff Aviation Products is a privately held, specialized aviation aftermarket business founded in 1985 by Chris Finnoff, headquartered at Rocky Mountain Metropolitan Airport in Broomfield, Colorado. The company develops, certifies, and sells performance-enhancement hardware for Pilatus PC-12 aircraft and, on a related basis, Beechcraft King Air platforms. Its core product portfolio comprises three lines: Pratt & Whitney PT6A-series turboprop engine upgrades (with over 100 PT6A-67P upgrades logged through 2022), cold-weather and engine-life-extending battery systems, and MT-Propeller's 5-blade and 7-blade propeller systems installed under partnership with MT-Propeller.

The company's stated engineering differentiation rests on over 40 years of PC-12 specialization, FAA-style certified component upgrades, and a track record of measurable performance outcomes (for example, MT 5-blade propeller uptake cited as equivalent to 150+ additional horsepower). Finnoff employs a small team (1–10) of aviation specialists drawn from a combined 50+ years of industry experience, and as of 2024 has been incorporated into a larger family of aviation companies while continuing to operate independently under the Finnoff brand.

Commercially, Finnoff operates a direct, consultative sales motion — quote-based pricing, personalized configuration support, direct phone/email contact, and an annual presence at NBAA BACE in Las Vegas. Revenue is generated through one-time hardware and certification sales (engines, propellers, batteries) supplemented by a transaction-based aircraft brokerage channel via aircraft.finnoff.aero. Customers are Pilatus PC-12 owners worldwide, served through both individual (private owner) and enterprise (corporate/operator) segments. No AI/ML capabilities, patents, regulatory actions, or external funding rounds are disclosed in the source data.

Direct peers

• Blackhawk Modifications: Pioneer of PT6A turboprop engine upgrade programs (SHP/HP) for King Air and other platforms via STC. Closely comparable to Finnoff's PT6A-67P engine upgrade work on PC-12, serving the same PT6A aftermarket with the same one-time hardware sale model.
• BLR Aerospace: STC developer of performance and safety modifications for King Air family (and other turboprops), including winglets and lighting. Same aftermarket-only, FAA-certified modifications business serving business aviation owners/operators.
• MT-Propeller Entwicklung GmbH: Manufacturer of the MT 5-Blade and 7-Blade composite propellers that are Finnoff's flagship product. Finnoff is the partner/installer for these props on Pilatus PC-12 and Beechcraft aircraft, so the two are tightly intertwined in the aftermarket channel despite MT being the upstream manufacturer.
• Raisbeck Engineering: Long-standing FAA STC developer of performance upgrade packages for Beechcraft King Air turboprops (and other business aircraft). Direct comparable in business model: certified, aftermarket, performance-enhancing modifications for a specific turboprop platform — Finnoff's playbook for PC-12.
• Tornado Alley Turbos: Specializes in PT6A engine upgrade kits and STCs for Beechcraft King Air. Same engine family, same turboprop aftermarket customer (high-net-worth and corporate operators), same certified-upgrade business model as Finnoff.

Broad incumbents

• Pratt & Whitney Canada: OEM manufacturer of the PT6A turboprop engine that Finnoff upgrades. Provides context on the engine platform underpinning all of Finnoff's upgrade work and is the ultimate technology licensor/source.
• Hartzell Propeller: Largest general-aviation propeller manufacturer with STC propeller offerings for King Air and PC-12. Competes with MT-Propeller (Finnoff's partner) and offers overlapping propeller upgrade paths to the same customer base.

Others

• Pilatus Aircraft Ltd: OEM of the PC-12 platform that all of Finnoff's products serve. Not a competitor, but the platform owner whose installed base, production cadence, and aftermarket stance directly shape Finnoff's opportunity.
