FAA Approved
Conditions:
Anti−torque failure, fixed tail rotor pitch setting.
Procedures:
Adjust power to maintain 50 to 60 knots airspeed.
Perform a shallow approach and running landing to a suitable area,
touching down into wind at a speed between effective translational lift
and 30 knots. Directional control may be accomplished by small adjust-
ments in throttle and or collective control.
ONE WAY LOCK FAILURE
NOTE
:
The one
−
way lock assembly is a self
−
contained hydraulic unit that prevents aft
feedback forces in the longitudinal cyclic control system.
Indications:
Aft feedback in the cyclic at high airspeed and/or during pull ups from
high airspeed or higher than normal forces required to move the cyclic
longitudinally.
NOTE
:
If the one
−
way lock has a push rod shaft or check valve seizure in the closed
valve position, a pull or push of 10 to 20 pounds will be necessary to open the
hydraulic relief valve and bypass the check valve. This additional pull or push will
be required for each subsequent longitudinal movement of the cyclic stick.
Temporary forces as high as 40 pounds may be experienced when flying in
turbulence.
Procedures:
Reduce airspeed to 100 KIAS or less.
Limit cyclic movement to those movements required to safely fly the heli-
copter. Abnormal or extreme control inputs are not necessary.
