Eparvier
H Eparvier was a manufacturer in Manthes, in southwestern France, who built 2 and perhaps 3 aircraft in 1909 and 1910.
The first was a large monoplane, designed probably in late 1908, with a long clear-doped fuselage uncovered in the middle, and a triangular fin and tailplanes. The undercarriage had castered wheels; the high-set tailwheel also trailed. A long streamlined tank sat on top of the fuselage just behind the pilot. The water-cooled 2-stroke 4-inline 40 hp Cote - sometimes a Prini-Berthaud - weighed 110 kg, the whole aircraft 350 kg.
A second Eparvier may have been a triplane that appeared in September 1909, powered with a Gnome, but this may have been a wholly different aircraft.
The second monoplane - and perhaps the third Eparvier - was similar to the Hanriot, appeared at Amberieu, near Lyon, in April 1910, and was still flying at the school 18 months later. The triangular fuselage was shorter than on the first design, completely covered; the undercarriage was made with 3 pairs of struts, 2 wheels and 2 long horned skids. The 50 hp engine was said to be Eparvier s own design, probably the earlier Cote modified. The tank was hung under the Bleriot-style pylon which braced the large rectangular deeply-curved wings. One 3-piece lifting elevator was mounted on the top of the rear fuselage just ahead of the trapezoidal rudder; there was no fin. The pilot sat well aft of the wings to balance the engine. Marius Lacrouze flew it in 1911.
