Shortly after take-off, the crew amended the flight plan and received clearance to go to the Hibernia platform first and then to the Sea Rose. [...] Figure 1 depicts the outbound portion of CHI91’s flight path prior to the red MGB OIL PRES warning message (solid green line), the point where the oil pressure loss occurred (see Point A), the return portion of the flight (red line), and the approximate position it impacted with the water (see Point B). [...] The inset shown in Figure 1 depicts the distance between Cape Spear and the direct track followed by the helicopter, from the diversion point to CYYT. [...] The impact with the water compromised the helicopter structure and the helicopter’s emergency flotation system did not deploy. [...] The cockpit area, including the flight controls and instrument panel, from the nose rearward to where the cockpit joins the main fuselage, was found lying under much of the forward cabin wreckage.
