Transient operation between 206% and 230% total torque is permitted for periods of not over 5 seconds for each occurrence. Operation between 206% and 230% total torque for more than 5 seconds or over 230% total torque for any period requires removal and overhaul of the main gearbox. With one engine operating transitory over-torque on the order of 150% Q is permissible provided the over-torque period does not exceed 20 seconds per application and the cumulative time above 135% Q does not exceed 30 minutes during the transmission overhaul period. Torque values and duration above 135% must be recorded. . NOTE 16 If takeoff power (CT58-140-1 or CT58-140-2) is used in cumulative excess of 5 minutes during any one emergency, the engine must be inspected in accordance with GE Commercial Maintenance Manual SEI-182, Revision 8 dated December 31, 1996 or later FAA approved revision.
