NOTES (cont’d)
NOTE 16. The T53-L-11 engine is rated to an output torque equivalent to 1100 horsepower at 6,600 RPM for
takeoff and 900 horsepower at 6,600 RPM for continuous operation. The T53 -L-13 gas turbine
powerplant in these installations is rated to an output torque value equivalent to 1400 horsepower
at 6,600 RPM take-off and 1250 horsepower continuous; however the transmission is restricted to
a maximum of 1100 horsepower at 6,600 RPM (50 PSI). The T53-L-13 and T53-L-13A engines
are limited to 97 percent gas generator speed or 24,400 RPM. The aircraft equipped with the T53 -
L-13B engines are not limited by this powerplant restriction; therefore, the pilot must ascertain
which engine is installed prior to start. Performance charts have been included in NAVAIR 01-
110HCA-1 to cover this reduction in power.
NOTE 17. Carriage of hazardous materials is prohibited unless compliance is shown with applicable
regulations in Code of Regulations Title 49, Part 175.

Airworthiness (ICA’s). Changes to the Type Design by means of a Supplemental Type Certificate
(STC) requiring ICA’s or changes to existing ICA’s must be submitted and reviewed by the Fort
Worth Aircraft Evaluation Group (FTW-AEG). Type Design Changes by means of a Field
Approval that require ICA’s must have those ICA’s reviewed by the Flight Standards District
Office (FSDO) managing the Field Approval or the FTW-AEG.
