This engine conforms to its United States type design (Type Certificate Number E22EA) and is in a condition for safe operation. 2. This engine has been subjected by the manufacturer to a final operational check and is in a proper state of airworthiness. Reference FAR Section 21.500, which provides for the airworthiness acceptance of aircraft engines or propellers manufactured outside of the United States for which a United States type certificate has been issued. Additional guidance is contained in FAA Advisory Circular 21-23, Airworthiness Certification of Civil Aircraft, Engine, Propellers, and Related Products, imported into the United States. NOTES NOTE 1. The engine ratings are based on static sea level conditions. Compressor inlet air (dry) 59˚F, 29.92 in. Hg. Compressor intake screen installed. No external accessory loads and no airbleed. NOTE 2. Emergency use of MIL-G-5572, (all grades) is permitted for a total time period not exceeding 150 hours during any overhaul period. It is not necessary to purge the unused fuel from the system when changing fuel types. For the PT6T-9, refer to the engine maintenance manual. NOTE 3. Pratt & Whitney Canada Service Bulletin 5001 lists approved brand oils. For the PT6T-9, refer to the engine maintenance manual. NOTE 4. This engine meets FAA requirements for opera tion in icing conditions when the intake system conforms with the Pratt & Whitney Canada Installation Manual instructions for inertial separation of snow and icing particles. NOTE 5. For the PT6T-3, PT6T-3B, PT6T-3BE, PT6T -3BF, PT6T-BG, PT6T-3D, PT6T-3DE, PT6T-3DF, and PT6T-6 models, the engine is certificated as a unit comprising two separate power sections with the capability of single engine operation with either power section alone in multi-engined helicopters. The unit is also approved as a single engine. In either event, the installation compatibility of the mixing gearbox components with the rotorcraft drive system will have to be established. NOTE 6. Phillips FPA-55MB anti-icing additive at a concentration not in excess of 0.15% by volume is approved for use in fuels for these engines. For the PT6T-9, refer to the engine maintenance manual. NOTE 7. 100% output shaft speed equals 6600 output shaft r.p.m. or 33,000 power turbine r.p.m. NOTE 8. Certain engine parts are life limited. These limits are listed in Pratt & Whitney Canada Service Bulletin No. 5002 as revised. For the PT6T-9, refer to the engine maintenance manual, airworthiness limitations section. NOTE 9. Power may be restored in hot day conditions by means of water or water/methanol injection when accomplished in accordance with the requirements of the Pratt & Whitney Canada. Installation Manual (PT6T). TCDS E22EA PAGE 8 NOTE 10. The above models incorpor ate the following characteristics: Model Characteristics PT6T-3 Basic model PT6T-3A Similar to PT6T-3 except fo r aluminum instead of magnesium gearbox castings. PT6T-3B Similar to PT6T-3 except fo r single power section contingency ratings and PT6T-6 compressor turbine components. PT6T-6 Similar to PT6T-3 except for 2 1/2 min rating; higher ratings and improved engine parts. PT6T-3BE Same as PT6T-3B except for deletion of the torque sharing function, and a higher limiter setting. PT6T-3D Same as PT6T-3B except for improved hot section hardware to allow for increased ratings. PT6T-3DE Same as PT6T-3D except continuous OEI replaced by 30 minute rating. PT6T-3DF Similar to PT6T-3DE except fo r improved hot section hardware to allow for increased ratings. PT6T-3BF Similar to PT6T-3B except 30 minut e OEI rating is equivalent to the 2 1/2 minute OEI rating. PT6T-3BG Similar to PT6T-3BE except 30 mi nute OEI rating is equivalent to the 2 1/2 minute OEI rating. PT6T-9 Similar to PT6T-3DF except for improved hot section to allow for increased ratings and new 30 second/2 minute OEI ra tings structure. The engine is also equipped with an engine electronic cont rol system (EEC). The software for the EEC has been developed and tested in accordance with the provisions of RTCA/DO178B, level A. The EEC has not been fire tested and, therefore, must not be mounted in a designate d fire zone. Lightning protection limits, including power quality, electromagnetic compatibility and interference for the EEC system are specified in section 6 of the installation manual. NOTE 11. Service bulletins, structural repair manuals, vendor manuals, aircraft flight manuals, and overhaul and maintenance manuals, which contain a statement that the document is approved by Transport Canada, are accepted by the FAA and are considered FAA approved unless otherwise noted. These approvals pertain to the type design only. NOTE 12. The PT6T-9 turboshaft engine configuration is similar to the PT6T-3 series turboshaft engine models. These engines have two identical free-turbine power-sections coupled to a common mixing gearbox module with a single output shaft. One engine inoperative (OEI) power is the rated engine power for operation with one power-section inoperative. ----END---- ``` ## ADs (3, in force first) - [AD 79-11-03](https://openairdocs.org/ad/79-11-03): Automatic Fuel Control · Pratt & Whitney Canada PT6T-3 and PT6T-6.
