L/R GBOX TEMP
Left / Right engine gearbox temperature is in the upper
red range (too high / above 120 °C).
Gearbox temperatures above the limit value of 120 °C can lead to a total loss of power
due to engine failure.
- Reduce power on affected engine.
- Increase airspeed.
CAUTION
At high ambient temperature conditions and/or at low
airspeeds with high power settings, it can be assumed that
there is no technical defect in the gearbox and that the above
mentioned procedure will decrease the temperature(s). This
might not be the case if the gearbox temperature does not
return to the green range. In this case perform a
precautionary landing on the nearest suitable airfield. Prepare
