The Bushliner 1850 is produced under the FAA’s Modernization of Special Airworthiness Certification (MOSAIC) framework, transitioning away from the traditional amateur-built model toward a standardized, factory-produced aircraft.

Under MOSAIC, the aircraft is fully manufactured by Bushliner using consistent production methods, documented quality control, and repeatable configuration standards. This eliminates the variability associated with amateur-built aircraft and creates a professionally produced platform designed for long-term serviceability and fleet operation.

This structure provides several operational advantages:

• Improved insurance eligibility due to standardized factory construction and documented conformity.

• Easier financing through lenders that typically require professionally manufactured aircraft rather than owner-built examples.

• Commercial utility capability, allowing use for operations such as training, aerial work, patrol, survey, utility transport, and other revenue-generating missions permitted under MOSAIC regulations (excluding passenger charter or air carrier operations).

Owners participate through aircraft configuration, delivery orientation, and operational familiarization, while Bushliner retains responsibility for production, quality assurance, and lifecycle support—delivering a modern utility aircraft designed to remain supportable and economically viable for decades.

FAR Part 23 Certification Statement

Full FAR Part 23 certification is planned for the Bushliner 1850 program and remains an active development objective. The aircraft is being engineered from the outset to support eventual Part 23 approval, enabling expanded operational capability, broader commercial use, and long-term fleet support under a fully certified aircraft standard.

Part 23 certification will allow operation within the normal category certification framework, supporting institutional ownership, commercial applications, financing acceptance, and global operational flexibility consistent with certified aircraft programs.

The Bushliner 1850 is powered by the DeltaHawk DHK-350, a modern twin-turbocharged, twin-supercharged compression-ignition engine producing 350 horsepower and approximately 707 ft-lbs of torque. Designed specifically for aviation use, the engine delivers strong low-RPM thrust and consistent power across the operating envelope, supporting heavy payload operations, short-field performance, and high-density-altitude environments.

Operating on globally available Jet-A fuel, the DeltaHawk platform aligns the aircraft with the aviation industry’s transition away from legacy 100LL leaded avgas, providing long-term fuel security and operational stability for owners and fleet operators.

Key characteristics include:

• 350 horsepower output

• 707 ft-lbs of torque available across the power range

• Twin turbo + twin supercharger architecture for altitude performance and immediate power response

• Targeted 3,000-hour TBO

• Approximately 15 GPH fuel burn, improving range and operating economics

• Liquid-cooled diesel design optimized for durability and simplified engine management

The DeltaHawk installation positions the Bushliner 1850 as a next-generation utility aircraft built for the post-100LL era—focused on dispatch reliability, global operability, and long-term lifecycle support.
