Figure 1. Map showing the probable route up the lake to the accident site (dashed/double-dotted line), the published VFR route to the west of the lake (dashed line) and the low ground route connecting the two (dotted line)
A line superimposed on a Google satellite image of the region west of Okanagan Lake between Kelowna and Penticton, British Columbia, shows the probable flight path. The line extends northward over the lake, then turns westward near Peachland to the accident site. Two other lines indicate, respectively, the published VFR route extending to the west of the lake, and the low ground route connecting the occurrence flight's probable flight path with the VFR route.
Figure 2. Modified sign at Penticton Airport
A photograph shows the sign installed at a new location at Penticton Airport with modified content, which reads: "NOTICE TO PILOTS / Due to high terrain surrounding this airport, it is recommended that pilots proceeding east or west under VFR attain an altitude of 5 000 feet (asl) minimum before leaving the Okanagan Valley. / Airport elevation is 1 129 feet (asl)".
Photo 1. Aerial view of the accident site, showing the likely flight path before the initial tree strike
A dotted line superimposed on an aerial photograph shows the last portion of the likely flight path over the tailings dam, the location of the initial tree strike, and the aircraft wreckage.
Photo 2. Fuel-flow indicator, 23 March 2012
A photograph of a portion of the instrument panel shows the same throttle setting and manifold pressure indications for both the right and left engines, but a fuel-flow indication that is 45% higher for the right engine than for the left.
