Identify the affected axis and helipilot by observing HELIPILOT indicators
(API), helicopter attitudes/rates and ADIs (normal and STBY).
Switch off the affected SAS.
If SAS disengagement eliminates the oscillation, leave it off.
If oscillation persists, re-engage both SAS and switch off the other SAS.
If oscillation occurs on yaw, switch off SAS 1 leaving SAS 2 on.
NOTE
SAS 2 pitch and roll actuators position may be observed by
pressing the monitor switch SAS 2 PUSH on HELIPILOT panel.
Proceed as follows:
Maximum airspeed : Less than 120 KIAS.
Maximum ROC : 500 ft/min.
Cyclic and collective : Hands on.
Proceed with flight.
WARNING
Landing shall not be attempted while oscillatory malfunction
exists.
AUTOTRIM MALFUNCTION
Autotrim malfunction is evidenced by observing an undesirable cyclic stick
motion.
If malfunction occurs put AUTOTRIM switch to OFF.
INTERCOMMUNICATION SYSTEM FAILURE
In case of failure of either intercommunication system proceed as follows on
the affected panel:
FAIL/NORM switch : Set to FAIL.
Resume to operate normally.
