The factory overhauled engines come with a 7000 hour TBO for commercial operators (FAR 135/121 or Canadian Equiv.) or a 5000 TBO for FAR 91 or non-commercial operators. There is one hot section at 3500 or 2500 hours respectively.
The Garrett Otter has the same fuel capacity as the standard Otter, because the fuel system operates essentially the same as the original Otter. The total capacity is 213 U.S. gal. Kal-Air Repair, Ltd. (one of our authorized installation centers) offers an STC’d extended range tank system that provides an additional 38 U.S. gal.
