Accident: Porpoise Bay, Sechelt, BC. 30-Sep-1979 The DHC-6 was at 200 feet on finals when it suddenly turned right and descended in a right wing-down attitude, crossing the shoreline and striking the ground. The aircraft cartwheeled into trees. The right-hand aileron bellcrank-to-aileron rod had separated from the bellcrank end fitting due to an extensive stress corrosion crack. This allowed the right-hand aileron to move up, causing asymmetric lift and irretrievable loss of control. The specified visual inspection of the rods was inadequate to detect stress corrosion cracking. Previous similar failures of flap rods on the DHC-6 had led to airworthiness action by the manufacturer and the DOT but these measures were not applied to the aileron rods which are of similar construction.
