After two failed take-off attempts due to light wind and high weight, the pilot began a take-off from outside the waterway. Low sun angle and high nose attitude restricted visibility of a submerged reef, resulting in a collision.

Background

The pilot had experienced two failed take-off attempts earlier in the day. They believed these failures were due to light wind and high aircraft weight. At the time of the accident take-off, the wind remained light and the aircraft was relatively heavy.

Take-off Attempt

To increase the take-off distance available, the pilot decided to start the take-off from a position outside the dimensions of the waterway. The tide was close to the low point, but the reef struck by the aircraft was still submerged.

Collision

The sun angle was low, increasing the amount of sunlight reflected from the water surface. At the speed of the collision, the aircraft nose attitude was at the highest angle for the take-off run. This condition, combined with the sunlight reflection, severely restricted the pilot's ability to detect the submerged reef before impact.
