NOTE 6 Torque may exceed 103 percent Q on one engine to a maximum of 123 percent, provided that the power of the other is reduced so that total torque for both engines does not exceed 206 percent Q for 30 minutes or 172 percent continuously, and that the single engine Ng, T5 and Q limits are not exceeded. The governing parameter is the limit which occurs first. NOTE 7 Provisions for the carriage of external loads are available in the form of structural hard points on the fuselage and single point hook. Information concerning the operating limitations with this equipment is contained in the Flight Manual. NOTE 8 Continued airworthiness of the USAF CH-3E helicopters eligible under this TCDS is contingent upon compliance with all applicable FAA Airworthiness Directives for the Sikorsky Model S61R helicopters, the General Electric CT-58 (Military Model T-58) engine, and any components installed thereon. NOTE 9 Prior to civil airworthiness certification, Siller Helicopters Engineering Report No. SH- 083, dated March 8, 1995 or later FAA approved revisions, must be incorporated. NOTE 10 These helicopters must be serviced and maintained in compliance with Siller Helicopters Continued Airworthiness Maintenance Report CH-3E, No. CH-3E-084 dated March 8, 1995 or later FAA approved revisions. NOTE 11 This aircraft is prohibited from carrying cargo for compensation or hire.
