§23.205 Critical engine inoperative stalls.

(a) A multiengine airplane may not display any undue spinning tendency and must be safely recoverable without applying power to the inoperative engine when stalled. The operating engines may be throttled back during the recovery from stall. (b) Compliance with paragraph (a) of this section must be shown with-- [(1) Wing flaps: Retracted and set to the position used to show compliance with Sec. 23.67.] (2) Landing gear: Retracted. (3) Cowl flaps: Appropriate to level flight critical engine inoperative. (4) Power: Critical engine inoperative and the remaining engine(s) at 75 percent maximum continuous power or thrust or the power or the thrust at which the use of maximum control travel just holds the wings laterally level in the approach to stall, whichever is lesser. (5) Propeller: Normal inoperative position for the inoperative engine. [(6) Trim: Level flight, critical engine inoperative, except that for an airplane of 6,000 pounds or less maximum weight that has a stalling speed of 61 knots or less and cannot maintain level flight with the critical engine inoperative, the airplane must be trimmed for straight flight, critical engine inoperative, at a speed as near 1.5 as practicable.]
