H. Following engine control cable maintenance, observe these requirements:
(1)
Control cables should not be deflected by fairleads, rub strips, or grommets from the rigged or normal operation position.
(2)
All pulleys should rotate freely with no interference with cable guards.
(3)
Control cables should not contact pulley or drum flanges for entire travel of cable.
(4)
Control cable pressure seals should be adjusted after cable rigging to eliminate any binding or deflection of cables (Ref 20-10-101, Control Cable Air Pressure Seal - Removal Installation).
