NOTE 10. To be eligible for use in certificated aircraft, the engine installation must include an accurate engine output torque
measuring device or an acceptable alternate means of determining engine power.
NOTE 11. This engine meets FAA requirements for operation in icing conditions, for adequate turbine disc integrity and rotor
blade containment and does not require airframe-mounted armoring.

1/140-2)
Power Turbine 23,100 r.p.m. for 15 seconds.
When either of these limits is exceeded, the engine must be disassembled for inspection.
NOTE 13. Because of differences in engine application and installation, each engine installation design must be evaluated
with regard to engine overspeed protection and an airframe-mounted speed switch provided if deemed necessary.
NOTE 14. Below 59°F the sea level static power limits for the CT58-110-1/-2 and CT58-140-1/-2 engines will vary as

For power rating variation between standard day conditions and the temperatures listed above, refer to General
Electric Operating Instructions No. 180 (CT58-110-1, 110-2) and No. 197 (CT58-140-1, 140-2). The ratings
referred to herein and the limitations on the usage of these ratings are defined in the applicable FARs.
Engines with individual performance characteristics and capabilities to develop the low temperature power ratings
noted above at higher ambient temperatures may be operated up to these power limits at any ambient conditions
provided all other engine parameters are not exceeded.
NOTE 15. The only optional additives which may be used in approved fuels are as follows:
(1) Phillips PFA-55MB or anti-icing additives to specification MIL-I-27686E at a concentration not in excess of
0.15% by volume.
(2) SOHIO Biobor JF biocide additive at a concentration not in excess of 20 p.p.m. elemental boron (270 ppm
total additive).
(3) Shell ASA-3 anti-static additive at a concentration that will provide not in excess of 300 conductivity units
which is approximately equivalent to 1 p.p.m.
The above additives may be used in combination.
With the fuel boost pump (Part Number 5183T66P01) installed, fuel system icing inhibitor ( FSII) must be added to
the fuel when flight conditions are known or forecast to be at or below 32 degrees F (0 degrees C).
NOTE 16. A speed decreaser gear defined by General Electric drawing 37R600175 is eligible for use on
CT58-110-1, -110-2 engines. This provides a gear reduction ratio of 3.25 to 1 and includes an integral torque
sensing device. Oil conforming to General Electric Specification No. 050TF1 must be supplied to the gear box
from the airframe oil supply system. Normal oil pressure operating limits for the gear box are 35 to 75 p.s.i.
NOTE 17. The CT58-100-2 and CT58-110-1 engines incorporate improved hot section parts to permit operation at higher
turbine inlet temperatures and increased ratings. The CT58- 100-2 does not utilize the higher rating.
"Military T58-GE-1 engines with serial numbers below 277135 were manufactured identical to the
CT58-110-1, and military T58-GE-5 engines with serial numbers below 285373 and below 291053 were
manufactured identical to the CT58-140-1. These engines are eligible for use in certificated aircraft if they
conform to the FAA approved parts lists, are in an acceptable airworthiness condition, and the engine nameplate
has been revised or replaced to include the corresponding civil model designation and Type Certificate number.
Consult General Electric for specified requirements. The T58-GE-1 and
T58-GE-5 models were removed from active certification status on 16 September 1971."
The CT58-140-1 engine is similar to the CT58-110-1 except for improved parts, increased airflow and compressor
efficiency.
The CT58-110-2 engine is similar to the CT58-110-1 with selected CT58-140-1 hardware incorporated for life and
performance improvements.
The CT58-140-2 engine is identical to the CT58-140-1 except for improved performance at above standard day
temperature conditions and an increased flow fuel control. Refer to NOTES 9 and 14.
NOTE 18. "Life limits established for critical rotating components are published in the CT58 Overhaul Manuals
SEI-102 (CT58-100-2/-110-1/-110-2) and SEI-183 (CT58-140-1, -2)."
