"The main engine failed to start on at least seven occasions during the period immediately leading up to the grounding, as particularised above. The exact reason for this is unknown pending full and proper disclosure by the claimant. However without prejudice to the foregoing, currently the most likely cause of the start failures was the malfunctioning of the governor system which is the primary speed control device for the main engine and/or the malfunctioning of the starting system or associated components."
