Sec. 25.231  Longitudinal stability and control.



    (a) Landplanes may have no uncontrollable tendency to nose over in 

any reasonably expected operating condition or when rebound occurs 

during landing or takeoff. In addition--

    (1) Wheel brakes must operate smoothly and may not cause any undue 

tendency to nose over; and

    (2) If a tail-wheel landing gear is used, it must be possible, 

during the takeoff ground run on concrete, to maintain any attitude up 

to thrust line level, at 75 percent of VSR1.

    (b) For seaplanes and amphibians, the most adverse water conditions 

safe for takeoff, taxiing, and landing, must be established.
