(1)
The meantorquefor maximum continuouspower multipliedby 1.25;
(2)
The torque required by Sec. 29.923;

73.3 Control Surface and System Loads
FAR 29.391 : General.
[Eachauxiliary rotor, each .xed or movable stabilizing or control surface, and each system operating any .ight control must meet the requirements of Secs. 29.395 through 29.399, 29.411, and 29.427.] Amdt. 29-41, E.. 11/28/97
FAR 29.395 : Control system.
(a)
The reaction to the loads prescribed in Sec. 29.397 must be provided by–
(1)
The control stops only;
(2)
The control locks only;
(3)
The irreversible mechanism only (with the mechanism locked and with the control surface in the critical positions for the e.ective parts of the system withinitslimit of motion);
(4)
The attachment of the control system to the rotor blade pitch control horn only (with the control in the critical positions for the a.ected parts of the system withinthelimits ofits motion); and
(5)
The attachment ofthe control systemtothe control surfacehorn(withthe controlinthe criticalpositionsforthe a.ectedparts of the system withinthe limits of its motion).
(b)
[Eachprimarycontrol system,including its supporting structure, mustbedesigned as follows :
(1) The system must withstandloads resulting fromthelimitpilotforcesprescri-bed in Sec. 29.397;
(2)
Notwithstandingparagraph(b)(3) of this section, whenpower-operated actua-tor controlsorpowerboost controlsareused,the system must also withstand the loads resulting from the limit pilot forces prescribed in Sec. 29.397 in conjunction with the forces output of each normally energized power device, including any singlepowerboost or actuator systemfailure;
