Sec. 29.67  Climb: One engine inoperative (OEI).



    (a) For Category A rotorcraft, in the critical takeoff configuration 

existing along the takeoff path, the following apply:

    (1) The steady rate of climb without ground effect, 200 feet above 

the takeoff surface, must be at least 100 feet per minute for each 

weight, altitude, and temperature for which takeoff data are to be 

scheduled with--

    (i) The critical engine inoperative and the remaining engines within 

approved operating limitations, except that for rotorcraft for which the 

use of 30-second/2-minute OEI power is requested, only the 2-minute OEI 

power may be used in showing compliance with this paragraph;

    (ii) The landing gear extended; and

    (iii) The takeoff safety speed selected by the applicant.

    (2) The steady rate of climb without ground effect, 1000 feet above 

the takeoff surface, must be at least 150 feet per minute, for each 

weight, altitude, and temperature for which takeoff data are to be 

scheduled with--

    (i) The critical engine inoperative and the remaining engines at 

maximum continuous power including continuous OEI power, if approved, or 

at 30-minute OEI power for rotorcraft for which certification for use of 

30-minute OEI power is requested;

    (ii) The landing gear retracted; and

    (iii) The speed selected by the applicant.

    (3) The steady rate of climb (or descent) in feet per minute, at 

each altitude and temperature at which the rotorcraft is expected to 

operate and at any weight within the range of weights for which 

certification is requested, must be determined with--

    (i) The critical engine inoperative and the remaining engines at 

maximum continuous power including continuous OEI power, if approved, 

and at 30-minute OEI power for rotorcraft for which certification for 

the use of 30-minute OEI power is requested;

    (ii) The landing gear retracted; and

    (iii) The speed selected by the applicant.

    (b) For multiengine Category B rotorcraft meeting the Category A 

engine isolation requirements, the steady rate of climb (or descent) 

must be determined at the speed for best rate of climb (or minimum rate 

of descent) at each altitude, temperature, and weight at which the 

rotorcraft is expected to operate, with the critical engine inoperative 

and the remaining engines at maximum continuous power including 

continuous OEI power, if approved, and

at 30-minute OEI power for rotorcraft for which certification for the 

use of 30-minute OEI power is requested.
