Do228 NXT Completes First Flight Ahead of ILA 2026 Debut

General Atomics AeroTec Systems (GA-ATS) will publicly unveil the Do228 NXT demonstrator aircraft at the ILA 2026 airshow in Berlin, marking the official restart of series production for the modernized twin-turboprop platform in Germany.

The upcoming debut, scheduled for June 10 to 14, 2026, follows the aircraft’s successful first flight from the company’s Oberpfaffenhofen facility on May 2, 2026. According to a press release issued by GA-ATS, the Do228 NXT integrates next-generation avionics and composite manufacturing refinements while retaining the short take-off and landing (STOL) capabilities of the legacy Dornier 228.

Flight testing and public debut schedule

The Do228 NXT demonstrator is currently undergoing a production test flight campaign. Engineering teams are evaluating the aircraft’s flight characteristics across various altitudes, speeds, and operational scenarios to validate the updated systems before its public presentation.

Martina Hierle, Test Pilot and Program Manager at GA-ATS, commanded the May 2 flight. She stated that the aircraft performed flawlessly and demonstrated its readiness for demanding global missions.

“This successful first flight is the result of incredible dedication and hard work from the entire team. With the Do228 NXT, we now have a modern aircraft that carries the legacy of the Do228 into the future,” Hierle said.

At ILA 2026, the aircraft will feature a special livery and appear in the static display area. Following the Berlin event, GA-ATS will present the Do228 NXT to the international market at the Farnborough Air-Shows in Hampshire, United Kingdom, from July 20 to 24, 2026.

Production restart at Oberpfaffenhofen

The original Dornier 228 completed its first flight nearly 45 years ago. The General Atomics Group acquired the Oberpfaffenhofen production facility approximately five years ago with the explicit goal of re-establishing a Manufacturing line for the updated airframe. The modernized Do228 NXT is positioned for versatile roles, including maritime patrol, disaster response, and passenger or Cargo-Aircraft transport.

GA-ATS Managing Director Craig Simpson described the aircraft as an answer to the demands of modern aviation rather than a simple upgrade. The company plans to conduct extensive customer demonstrations, trade show appearances, and demo tours throughout the remainder of 2026 to showcase the platform’s special mission equipment and modernized cabin.

AirPro News analysis

The successful flight of the Do228 NXT demonstrator represents a significant industrial milestone for the German aerospace sector, effectively reviving a proven utility airframe with modern systems. We view the integration of contemporary avionics and composite components as a necessary step to keep the platform competitive against other twin-turboprop utility aircraft in the special mission and regional cargo markets. The decision by General Atomics Group to invest in the Oberpfaffenhofen line indicates strong anticipated demand for rugged, STOL-capable aircraft in maritime and disaster response applications, where the legacy Dornier 228 previously excelled.
