Piper Aircraft Adds 7-Blade MT-Propeller Option for M700 FURY

This article is based on an official press release from Piper Aircraft.

At the Sun ‘n Fun Aerospace Expo in Lakeland, Florida, on April 14, 2026, Piper Aircraft announced a significant upgrade for its flagship single-engine turboprop. The manufacturer will now offer a 7-blade composite MT-Propeller as a factory option for the M700 FURY. According to the company’s press release, the new propeller system has already secured Supplemental Type Certificate (STC) approval from the European Union Aviation Safety Agency (EASA), with Federal Aviation Administration (FAA) certification expected in the near future.

The introduction of the 7-blade propeller promises operators a suite of performance enhancements, including shorter takeoff distances and improved climb rates. Furthermore, the aerodynamic efficiency of the high-blade-count design delivers a noticeable reduction in both cabin and community noise. To mark the occasion at Sun ‘n Fun, Piper displayed the new MT-Propeller on an M700 FURY adorned in a special red, white, and blue livery, celebrating America’s upcoming semiquincentennial (250th) anniversary.

This development highlights a growing industry trend toward advanced composite propellers designed to maximize turboprop efficiency while complying with increasingly stringent international noise regulations. The factory option is available immediately for new aircraft orders, while existing European customers are encouraged to contact regional dealers for the STC upgrade.

Performance Enhancements and Certification Milestones

Engineering the “Silent 7”

The 7-blade propeller, often marketed under MT-Propeller’s “Silent 7” series, is constructed using a highly developed structural resin-infused wood core wrapped in carbon-fiberglass composite skins. According to the manufacturer’s specifications, the blades feature bonded nickel alloy leading edges to provide superior protection against erosion and Foreign Object Damage (FOD).

By distributing the engine’s thrust across seven blades, the propeller achieves a smaller overall diameter. This reduction in diameter lowers blade-tip speeds, which is the primary source of propeller noise. A Piper spokesperson noted during the announcement that the new design reduces internal cabin noise by approximately 3 decibels, significantly enhancing passenger comfort while simultaneously decreasing the aircraft’s external noise footprint.

“This option provides operators with improved takeoff and climb performance while reducing noise levels for both passengers and communities,” stated Marc Ouellet, Vice President of Engineering and Manufacturing at Piper Aircraft.

EASA Approval and FAA Outlook

Securing EASA STC approval prior to FAA certification is a notable milestone for the M700 FURY program. While FAA certification is pending and expected shortly, the immediate European approval allows Piper to cater to a market where noise compliance is paramount. The composite blades boast no life limitation and are fully repairable. Furthermore, industry data indicates that in July 2025, MT-Propeller increased the Time Between Overhaul (TBO) for its 7-blade turboprop series to 3,600 hours or six years, citing excellent wear resistance during field inspections.

The M700 FURY and MT-Propeller Legacy

Piper’s Flagship Turboprop

To understand the impact of this upgrade, it is essential to look at the aircraft receiving it. Announced in February 2024 as the successor to the M600/SLS, the M700 FURY is the fastest single-engine aircraft in Piper’s 87-year history. Powered by a Pratt & Whitney Canada PT6A-52 engine producing 700 shaft horsepower (shp), the aircraft boasts a maximum cruise speed of 301 knots true airspeed (ktas) and a maximum range of 1,852 nautical miles at normal cruise speeds.

The M700 FURY features a 6,000-pound Maximum Gross Takeoff Weight (MGTOW), which keeps it BasicMed compliant in the United States. Since receiving its initial FAA certification in February 2024 and EASA type certification in October 2024, Piper has handed over more than 100 units to customers, underscoring the platform’s strong market reception.

MT-Propeller’s Proven Track Record

Headquartered in Straubing, Germany, MT-Propeller Entwicklung GmbH has been a leader in natural composite propellers since its founding in 1981. Prior to its integration on the Piper M700 FURY, MT-Propeller successfully certified its 7-blade technology on several other high-performance turboprops. These include the Pilatus PC-12, the Beechcraft King Air 300/350 series, and the Short Skyvan, proving the design’s reliability and performance benefits across diverse airframes.

AirPro News analysis

We view Piper’s decision to prioritize EASA certification for the 7-blade MT-Propeller as a highly strategic maneuver. European countries enforce some of the strictest aviation noise regulations globally, such as Germany’s Landeplatz Lärmschutz Verordnung. Aircraft that exceed specific noise thresholds often face restricted operating hours, higher landing fees, or outright bans at certain airfields. By integrating a propeller system that significantly lowers the noise profile, Piper ensures the M700 FURY can operate unhindered across European airspace.

Furthermore, as turboprop engines like the 700-shp PT6A-52 become more powerful, manufacturers must find ways to absorb that power efficiently. Adding more blades is an elegant engineering solution that avoids increasing the propeller’s diameter. Beyond the tangible performance and compliance benefits, we note that multi-blade propellers offer a distinct, aggressive “ramp appeal” and a smoother, jet-like sound. These aesthetic and sensory enhancements are highly attractive selling points for owner-operators in the competitive luxury turboprop market.

Frequently Asked Questions

What are the main benefits of the 7-blade MT-Propeller on the M700 FURY?

According to Piper Aircraft, the 7-blade propeller decreases takeoff roll, increases the rate of climb, and reduces cabin noise by approximately 3 decibels compared to the stock 5-blade propeller.

Is the 7-blade propeller available for existing M700 FURY owners?

Yes. While it is available as a factory option for new aircraft, existing European customers interested in the STC upgrade can contact their regional Piper dealers to have the new propeller retrofitted.

When will the 7-blade propeller be certified in the United States?

The propeller has already received EASA STC approval in Europe. Piper Aircraft states that FAA certification is pending and is expected “in the near future.”
