must consist of at least the following 
maneuvers: 

(1) Pickup of the external load. 
(2) Demonstration of adequate direc-

tional control while hovering. 

(3) Acceleration from a hover. 
(4) Horizontal flight at airspeeds up 

to the maximum airspeed for which au-
thorization is requested. 

(5) Demonstrating appropriate lifting 

device operation. 

(6) Maneuvering of the external load 

into release position and its release, 
under probable flight operation condi-
tions, by means of each of the quick-re-
lease controls installed on the rotor-
craft. 

(d) Class C rotorcraft-load combina-

tions: For Class C rotorcraft-load com-
binations used in wire-stringing, cable-
