NOTE 8. SPECIAL ANTI-ICING OR DE-ICING REQUIREMENTS Not Applicable NOTE 9. ENGINE MOUNT SYSTEM PROVISIONS Refer to Installation Manual. NOTE 10. POWER BOOST, INJECTION OR AUGMENTATION SYSTEMS Not Applicable NOTE 11. SPECIAL INSTALLATION REQUIREMENTS The uninstalled engine meets FAA requirements for operating in icing conditions. These engines also meet the requirements of Canadian Airworthiness Manual 533.68 for operation in icing conditions as defined in Canadian Airworthiness Manual 529, Appendix C. The Airframe Manufacturer must give appropriate consideration to installation effects as stated in the Installation Manual. The software for the Electronic Engine Control (EEC) has been developed and tested in accordance with the provisions of "Flight Critical" category (Level A) of RTCA/DO178B or DO178C for the PT6C-67D, PT6C-67C, PT6C-67C1 and PT6C-67E. Lightning protection requirements and electromagnetic interference emitted by the electronic engine control system, including cables, are specified in the Installation Manual The PT6C-67C, PT6C-67C1, PT6C-67D & PT6C-67E EECs have not been fire tested and therefore, must not be mounted in a designated fire zone TCDS E00068EN Page 4 of 5 NOTE 12. MANUFACTURER’S SERVICE BULLETINS OR OTHER INSTRUCTIONS COVERING MATTERS OF INTEREST Service Bulletins, structural repair manuals, vendor manuals, aircraft flight manuals, and overhaul and maintenance manuals, which contain a statement that the document is Transport Canada approved, are accepted by the FAA and are considered FAA approved. These approvals pertain to the type design only. NOTE 13. SPECIAL OPERATING PROCEDURES Mechanical limits controlled by engine software enable the management of rotorcraft limitations within the certified engine thermal ratings for the PT6C-67D, -67C, 67C1 and 67E engines. The PT6C-67A receives gas generator rotor speed demand via analog electrical signals directly from the aircraft Flight Control Computers (FCCs). The FCC is required to limit the interturbine temperature (ITT) during the application of the 30 second one engine out (OEI) power. NOTE 14.

The aircraft must not be issued a standard airworthiness certificate or approved for return to service until the ICA are complete and determined acceptable. NOTE 16. IMPORT REQUIREMENTS To be considered eligible for installation on U.S. - registered aircraft, each engine to be exported to the United States shall be accompanied by a certificate of airworthiness for export or certifying statement endorsed by the exporting cognizant civil airworthiness authority and containing the following language: (1) This engine conforms to its United States type design (Type Certificate Number E00068EN) 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 14 CFR Section 21.500, which provides for the airworthiness acceptance of aircraft engines or propellers manufactured outside of the U.S. and for which a U.S. type certificate has been issued. Additional guidance is contained in FAA Advisory Circular 21-23, Airworthiness Certification of Civil Aircraft, Engines, Propellers and Related Products, Imported into the United States. NOTE 17. LIFE LIMITED PART INFORMATION Certain engine parts are life limited. For PT6C-67C, PT6C-67C1, PT6C-67D, PT6C-67E & PT6C-67A engines, these life limits are listed in PWC maintenance manual P/N 3056642 for the PT6C-67D, P/N 3045332 for PT6C-67C & PT6C- 67C1, P/N 3072872 for the PT6C-67E and P/N 3045082 for the PT6C-67A.
