Narrative:The float-equipped Twin Otter passenger plane departed Victoria Harbour at 17:18 for a 20-minute flight to Vancouver Harbour water aerodrome (CXH). At 175 feet, while on final approach, a loud noise was heard. The aircraft yawed to the left and plunged into the harbour in a left-wing and nose-down attitude, 2500 feet short of the landing area.
PROBABLE CAUSE: In-flight failure of the left-hand inboard flap control rod that led to a sudden retraction of the complete left-hand flap system and sudden loss of control. The inboard span-wise push-pull flap control rod (inboard bell-crank to inboard rod) was severely stress-corroded and had at least three longitudinal cracks; the rod had separated from its inboard fitting.
