About the Petrel Aircraft Petrel

The Petrel is a light-sport amphibious aircraft designed and manufactured by Petrel Aircraft in the United States, certified under the LSA category in the mid-2010s. Built for pilots who want the freedom to operate from both conventional runways and water, the Petrel combines a high-wing configuration with retractable landing gear and a boat-hull fuselage, making it one of the few factory-built amphibians available in the light-sport category. Its single Rotax 912-series engine delivers modest cruise speeds around 90 knots, but the aircraft's real appeal lies in its versatility and relatively low operating costs compared to legacy amphibians like the Icon A5 or heavier seaplanes.

With a maximum takeoff weight of 1,430 pounds and a stall speed as low as 35 knots in landing configuration, the Petrel is forgiving and accessible to sport pilots, yet capable enough for backcountry lake hopping and coastal exploration. The type's operational envelope is typical of LSA aircraft (never-exceed speed of 120 knots and a max structural cruising speed of 95 knots), but its amphibious capability opens up thousands of waterways that remain off-limits to land-only light aircraft. The Petrel has found a niche among recreational pilots and flight schools focused on seaplane training, particularly in regions with abundant lakes and coastal waterways.
