§27.1143. Engine controls.
14 C.F.R. § 27.1143
There must be a separate power control for each engine.
Power controls must be grouped and arranged to allow—
Separate control of each engine; and
Simultaneous control of all engines.
Each power control must provide a positive and immediately responsive means of controlling its engine.
If a power control incorporates a fuel shutoff feature, the control must have a means to prevent the inadvertent movement of the control into the shutoff position. The means must—
Have a positive lock or stop at the idle position; and
Require a separate and distinct operation to place the control in the shutoff position.
For rotorcraft to be certificated for a 30-second OEI power rating, a means must be provided to automatically activate and control the 30-second OEI power and prevent any engine from exceeding the installed engine limits associated with the 30-second OEI power rating approved for the rotorcraft.
