§ 121.293 Special airworthiness re-

quirements for nontransport cat-
egory airplanes type certificated 
after December 31, 1964. 

No certificate holder may operate a 

nontransport category airplane manu-
factured after December 20, 1999 unless 
the airplane contains a takeoff warning 
system that meets the requirements of 
14 CFR 25.703. However, the takeoff 
warning system does not have to cover 
any device for which it has been dem-
onstrated that takeoff with that device 
in the most adverse position would not 
create a hazardous condition.
