C-FTIY, a privately operated Christavia MK I Amateur Built aircraft, was conducting a local flight from the Indus/Winters Aire Park, AB (CFY4) with only the pilot on board. This was the first flight after the installation of a new propeller and a cylinder in the Teledyne Continental O-200A engine. Shortly after lift-off from Runway 34, the performance wasn’t as expected and the pilot reduced the power to land; however, directional control could not be maintained.
The aircraft nosed over in a wheat field to the west of the runway, and came to rest on its back;
the pilot was uninjured.
