SilverLight AR-1 First US Factory-Built Gyroplane Compliant with FAA MOSAIC

This article is based on an official press release from SilverLight Aviation.

On April 22, 2026, Florida-based SilverLight Aviation announced a historic milestone for the United States general aviation and rotorcraft market. According to a company press release, its flagship AR-1 gyroplane will officially become the first American-made production gyroplane offered as a fully factory-built aircraft compliant with the Federal Aviation Administration’s (FAA) new MOSAIC and ASTM standards.

For over a decade, U.S. aviation regulations prohibited the sale of fully factory-built gyroplanes in the light-sport category, forcing buyers to purchase kits and assemble the aircraft themselves under experimental amateur-built rules. With the FAA’s recent regulatory overhaul, this barrier has been removed. SilverLight Aviation states that it is currently taking orders for the factory-built AR-1, marking a new era of accessibility for flight schools and rotorcraft enthusiasts.

Based on the company’s production timeline, the first MOSAIC- and ASTM-compliant factory-built AR-1 gyroplanes are scheduled for delivery in October 2026. This delivery window aligns closely with the official implementation of the new FAA rules governing airworthiness certification.

The Impact of the FAA MOSAIC Rule

Breaking the Kit-Built Barrier

To understand the significance of SilverLight Aviation’s announcement, it is essential to look at the regulatory framework that previously governed U.S. airspace. Historically, the FAA’s Light Sport Aircraft (LSA) category excluded fully assembled gyroplanes. According to historical context provided by Plane & Pilot Magazine, this restriction forced U.S. pilots to rely on builder-assist programs, while European countries operating under different regulations experienced a boom in factory-built gyroplane popularity.

The Modernization of Special Airworthiness Certification (MOSAIC) rule, approved in July 2025, represents one of the most significant overhauls to general aviation regulations in decades. Based on data from the FAA Federal Register, MOSAIC expands the definition of light-sport aircraft by replacing static weight limits with performance-based criteria. Crucially, it officially allows the certification and sale of factory-built gyroplanes. These changes affecting the airworthiness certification of new aircraft officially take effect on July 24, 2026.

Inside the SilverLight AR-1 Gyroplane

Design and Performance Specifications

The AR-1 is manufactured domestically at SilverLight Aviation’s 12,000-square-foot facility located at the Zephyrhills Municipal Airport in the greater Tampa Bay area of central Florida. According to the manufacturer’s specifications, the AR-1 is a modern, pusher-style gyroplane engineered to navigate turbulence and high winds smoothly.

The aircraft boasts a versatile speed range of 25 mph to 110 mph, making it suitable for both cross-country travel and leisurely sightseeing. SilverLight Aviation notes that the AR-1 features a high-inertia Stella aluminum alloy rotor system manufactured by Averso, mounted on a high-strength welded stainless-steel frame with composite fairings. Additionally, the company offers a convertible option known as the AR-1C, which allows pilots to switch between a semi-open cockpit with windshields and a fully enclosed canopy equipped with cabin heat.

Powerplant options for the AR-1 rely on field-proven Rotax engines. According to the company’s release, buyers can choose configurations ranging from the 100 HP Rotax 912ULS to the fuel-injected, turbocharged 141 HP Rotax 915iS, which is specifically recommended for high-altitude performance.

Leadership and ASTM Compliance

Meeting the new FAA requirements required rigorous adherence to newly established ASTM consensus standards. Abid Farooqui, President and Founder of SilverLight Aviation, personally participated alongside other industry experts in drafting the ASTM standards for gyroplanes to ensure alignment with the MOSAIC rule.

“We have been working directly with the industry and FAA to complete the ASTM standards required by MOSAIC and are confident that our aircraft will meet and exceed these standards,” Farooqui stated in the press release.

Broader Industry Implications

AirPro News analysis

We view SilverLight Aviation’s transition to factory-built manufacturing as a critical step in closing the competitive gap between the United States and Europe. For years, European manufacturers have dominated the modern gyroplane market because their regulatory environment permitted ready-to-fly sales. By achieving MOSAIC compliance, SilverLight’s AR-1 levels the playing field, allowing an American company to capture domestic demand without the friction and time investment of kit-building.

Furthermore, we anticipate that this development will significantly lower the barrier to entry for sport pilots. Gyroplanes are generally recognized as being easier to operate, highly tolerant of strong winds, and more affordable to purchase and maintain than traditional helicopters. By offering a factory-built option, rotorcraft flight becomes accessible to a much broader demographic. Economically, the ability to sell ready-to-fly aircraft is expected to stimulate the U.S. light-sport manufacturing sector, potentially creating jobs and boosting local economies, particularly in central Florida where SilverLight is based.
