chimbu warrior, I have a vague recollection that the person who bought the maintenance side of O'Connor Airlines (De Bruyen ?) was working on a maintenance schedule for the C441.
After all, I believe that the time limit on the C441 was the "nail in the coffin" for O'Connors as it immediately grounded their machine. However, as always, I may be mistaken and I am sure someone here will correct me.
