Austro Engine Surpasses 5 Million Flight Hours Across Global Diamond Aircraft Fleet

Wiener Neustadt, Austria, December 15, 2025 - Austro Engine proudly announces a major milestone: the global fleet of Diamond Aircraft powered by Austro Engine technology has now accumulated over 5 million “Life in Network” (LIN) flight hours. This achievement underscores the reliability, efficiency, and performance of Austro Engine’s powerplants, which have become the backbone of Diamond Aircraft’s modern piston-engine platforms.

Tracking of fleet hours began in 2009, and today there are well over 5,500 Austro Engine units in service, operating in 82 countries worldwide. These engines power Diamond’s most popular aircraft such as the DA40 NG single-engine and DA42-VI and DA62 twin-engine aircraft, which are widely used by flight schools, private owners, and special mission operators around the globe. The milestone reflects the trust placed in Austro Engine by thousands of operators and highlights the engines’ proven reliability in diverse environments.

What are LIN flight hours? LIN (Life in Network) flight hours represent the cumulative operational time of engines across the entire global fleet, tracked through Austro Engine’s integrated monitoring systems. This metric provides a precise measure of real-world reliability and performance, as it aggregates data from thousands of aircraft operating in varied conditions worldwide.

“Reaching 5 million flight hours is a testament to the reliability and innovation behind our engines,” said Jürgen Schwarz, General Manager of Austro Engine. “We are proud to support Diamond Aircraft and operators worldwide with powerplants that deliver exceptional performance and efficiency, day after day.”

Jürgen Schwarz, Managing Director of Austro Engine, speaks about the E4-Series reaching 5 million flight hours in a factory setting.
