ANTI−TORQUE FAILURE − GENERAL
Different types of failure may require slightly different techniques for optimum
success in recovery. Therefore, it is not possible to provide a standardized solution
for an anti−torque emergency.
ANTI−TORQUE FAILURE − COMPLETE LOSS OF THRUST
This involves a break in the fan drive system (ie., a broken drive shaft) that causes
the fan to stop turning resulting in a complete loss of fan thrust. Directional control
becomes dependent on airspeed and power setting.
Indications:
Inability to Ftrim" helicopter with pedals.
Conditions:
In Forward Flight
Procedures:
F
Adjust airspeed and power for level flight between 80 and 100 KIAS.
Do not attempt an autorotation from forward flight unless an actual
dual engine failure occurs.
F
Perform a shallow approach and running landing to a hard surface or other
suitable area. If possible select an approach direction that offers a left quarter
ing headwind to reduce the touchdown ground speed and the amount of right
yaw.
NOTE
:
Touchdowns made into the wind between 20 and 30 KIAS, may provide good
directional control at reduced power (collective) settings.
F
An aggressive reduction in power (collective) as the aircraft is decelerated dur
ing the final approach should yaw the aircraft to the left.
F
As the ground is neared, adjust collective as necessary to align the aircraft
with the touchdown direction and cushion the landing.
F
During ground run out adjust collective to maintain directional control. If neces
sary, during touchdown and ground run out, reduce rotor RPM by rotating
both twist grips simultaneously towards IDLE to assist in maintaining direc
tional control.
NOTE
:
Use of the twist grips to change RPM is generally not recommended due to the
complexity of manipulating both twist grips simultaneously and now having both
engines in the manual mode. If needed, it is recommended that they be used only
to reduce RPM just prior to or at the moment of touchdown.
